Are you a real T-MAN?

2010 April 16
by Alan Aragon

WARNING: This article contains links to a website whose images might be a little too hardcore for your workplace.

In my daily stroll through the internetz, I stumbled upon this article by fitness journalist/dating expert Nate Green who interviews fellow staff writer Dr. Lonnie Lowery. Before I get into this, let me first thank the good fellas at Tmuscle for providing a relentless source of entertainment. Not to mention, they always come through with great pics & vids of super-enhanced fleshiness. Nate’s article embodies so much of the Tmuscle ideals in a single swoop, that it deserves a little shine here on my Super Secret Blog™. Here are some key quotes from the article, followed by my two cents.

“If guys would simply load up on carbs and protein before their training sessions, take in high-quality amino acids during their workouts, and have another solid meal post-workout, they’d take advantage of the most anabolic time of the day and build serious muscle.”

The above isn’t a counterproductive recommendation. In fact, for most trainees, it’s a good idea to sandwich the training bout with protein & carbs. However, if a protein-rich meal or shake was consumed near the start of the training bout, intraworkout amino acid intake is redundant, especially for typical-length sessions lasting about an hour. The preworkout meal is already being digested, and amino acids are already being absorbed into circulation. One little wrinkle:  if what you’re drinking during the bout can improve your mood, this can potentially drive better performance. But most of all, nothing screams “I’m hardcore!” like walking around the gym with your chest puffed and lats flared, clutching a jug of bright pink fluid.

“Well, when it comes to protein synthesis — the necessary reaction that must happen to build muscle — the hormone insulin plays a huge role. Simply, the higher you spike insulin, the more protein synthesis will occur, and the more muscle you can build.”

The above statement is a combo of oversimplification and exaggeration. Even when amino acid levels are kept elevated, insulin’s ability to max-out net muscle protein balance has a ceiling that’s easily reached by a normal-size protein/carb meal or shake. A large mixed meal or shake can cause insulin levels to far surpass this limit. This is why researchers have alluded to insulin’s role in furthering net protein balance as more permissive than it is stimulatory [1]. On a sidenote of trivia, insulin has been seen to cause protein synthesis on its own when intravenously raised to 1000 times normal basal levels [2]. But alas, we’re talking about orally ingested/nutrient-mediated insulin elevations, not intravenous super-dosing for pharmacological effects. 

Think of it this way: if you buckle down for two hours, feed your body high-quality protein and carbs, spike insulin, train hard, and re-feed your body afterward, you’re almost guaranteeing that every amino acid is getting pumped straight into your muscles. You’ve created the ultimate anabolic environment, and, if you’re following the super-effective Anaconda Protocol, you’re taking in a whopping 1,157 calories of muscle-building nutrients and 167 grams of protein.

This is where Tmuscle takes the more-is-better principle and exploits it to an explosive end, literally. Linked in the quote above, the Anaconda Protocol is a true test of maximal human stomach capacity, which isn’t the best test to run during a hard training session. If the user feedback in this thread means anything, we should all hope that stain-free versions of the supplements are in development. There’s really no technical criticism needed here; just picture consuming a half-day’s worth of calories plus an entire day’s worth of fluid within a couple of hours. And somewhere within that timeframe, you must complete an intense workout before having to run to the sink or the toilet.

“I have no idea where that notion came from,” says Lowery. “My guess is that they took a 180-pound guy, gave him one gram of protein per pound of bodyweight, and divided that by six meals to get 30 grams per meal. And for some reason, people seem to think that it’s the ‘magic’ number. It’s just not correct.”

Well, its refreshing to see them get something right. The problem is, Lowery appears to be contradicting the more-is-better mantra in a fairly recent article where he says, “I’ve actually cut back on the amount of protein I eat at any given time. I just make sure I spike it with leucine. I usually put a scoop and a half, about 7 or 8 grams, of leucine in just 20 grams of protein. But I’ve stopped sucking down 50 or 60 grams of protein at a time. I just don’t do that anymore; I don’t think it has that much benefit. Plus this prevents me from becoming a protein oxidizer or burner.”  This makes you wonder just how genuinely supportive Lowery is of the 167-gram  protein dose in the Anaconda Protocol.

The Perfect Carbs: According to Lowery, the perfect blend of carbs to consume before a workout should be insulinogenic (spikes insulin), but not anything containing straight sugar or high-fructose corn syrup. “I’m all for special dextrins [like the rice oligodextrin found in FINiBAR™ that will support high-level performance," he says. "You can't just sit down and have a giant bowl of Applejacks."

The above passage contradicts itself. Finibars have been marketed as a product that provides a steady release of carbs. "Fuel for the finish" is the product's tag line.  The bar's primary ingredient is isomaltulose (also called palatinose), which has been demonstrated to elicit a low-glycemic, low-insulinemic response [3]. With all their hype surrounding the prodigious spiking of insulin, it seems they chose the wrong carb to drive their point. Personally, I’d rather have a bowl of Applejacks in milk over a Finibar.

The Perfect Protein: For protein, Lowery’s a fan of hydrolysates [like the casein hydrolysate found in ANACONDA™, which are proteins that enter the blood stream quickly and significantly increase the rate of protein synthesis.  "Remember, the faster the amino acids hit the bloodstream and more protein synthesis you create, the better off you'll be," says Lowery.

Like the erroneous use of Finibars as an example of the "perfect carb" for spiking insulin, touting casein hydrolysate as the "perfect protein" has its own caveats.  While one study showed that casein hydrolysate is more quickly digested and absorbed than intact casein [4], another study found that the faster absorption of casein hydrolysate isn’t necessarily superior for muscle anabolism [5]. Compared to intact casein, its hydrolyzed form was preferentially incorporated into the intestinal tissue instead of skeletal muscle (more discussion here). Given this sparse and equivocal data set, calling casein hydrolysate “perfect” is a perfect example of unsubstantiated hype.

And, you can’t drink chocolate milk and eat sugary cereal to get the same effect. That’s not the 3rd Law of Muscle. That’s eating crappy food. You need quality nutrients from specialized carbs like rice oligodextrin, and specialized proteins like casein hydrolysate.

So, what does it mean when the crappy food  is more micronutrient-dense, and has equal or more supporting research than the perfect stuff?

What the fulk?

2010 April 2
by Alan Aragon

That was then (left), this is now (right)

The above pics are of a client and friend of mine named Phillip. For the sake of illustrating a point, I’ll let you guess his weight in both pics (hint: they are not the same). One thing that is almost universally agreeable is that he looks better in the right pic. Some of you might disagree, but most of you won’t. Another thing that’s hard to dispute is that he’s probably healthier in the right pic, as far as a blood chemistry might show.

Bring on the pounds

To achieve the look of the left pic, Phillip fulked. That’s a word I made up that means he fat-bulked. Prior to my supervision, he perused the bodybuilding message boards and adapted a plan whose objective was to gain lots of size & strength quickly. His daily consumption was a pretty standard maintenance diet, but with an entire gallon of whole milk on top of that. Lots of strength was gained, and yes, a lot of weight was gained as well.

After the gain…

After the fulking stint, Phillip lost a bunch of weight due to an extended hiatus from the gym. This is when he sought my help. I put him through a progression that kept him within 10-15 lbs of his post-fulk deflation, but looking worlds better. I’d like to emphasize that Phillip is not genetically blessed in the muscle gain or fat loss department. He’s only had his monstrous work ethic to rely upon for results. I know I said I’d have you guess the weight difference between pics, but surprise, I’ll give it away right here: Phillip was 216 lbs in the left photo, and 176 lbs in the right one. That’s 40 fricking pounds!  Does he really look 40 lbs lighter? I’ll let you be the judge. What’s more easily apparent is five inches less waist girth, and a magic chest lift.

Men: afraid to lose?

Everyone’s familiar with the common scenario where female trainees can gain a few pounds and start panicking, regardless of positive changes in body composition. Well, a lot of men have the opposite but equally irrational fear that weight loss automatically equates to unsightly results. This makes them seek out the fulking route, finding comfort in seeing pounds rapidly pile up on the scale. This can be a good or bad thing – depending on how you look at it, and of course, depending on the individual situation.

Keep in mind that I am not blanketly condemning rapid weight gain.  What I’m trying to convey is that more isn’t always better when it comes to racking up pounds.

Starting to look back a lot more.

2010 March 22
by Alan Aragon

 /></p> <p><strong>Let's talk about haystacks for a second</strong></p> <p>The beauty of this forum is that I can talk about whatever the hell I want, without reproach. Or something like that. Anyway, I'm in a sentimental mood for the moment. It might just be a side-effect of being dangerously close to turning 40. I remember almost exclusively looking ahead when I turned 30. But now, as I approach what statistically is likely to be the halfway point of my life, I find myself constantly looking back - thinking about what I can do <em>better</em> moving forward.</p> <p>That pic above, taken last week, is me & my two sons at a neighboring farm. Standing atop that pyramid of hay held a special type of significance. Just last year, my youngest one was too fearful to climb past the first step, and this year he made it to the second to the top row. Next year it's virtually certain he'll ascend to the top with no trace of apprehension in sight. This is the hope and anticipation of all parents - and of anyone in a position of nurturing young minds.</p> <p><strong>Career coach for a day</strong></p> <p>Just yesterday I presented at the annual career symposium at California State University, Northridge. First off, I think it's amazing that I get continually get asked back to present to a college where, during my undergrad, one of my professors incredulously asked, <em>

The fact of the matter is, I wasn’t always a model student. My original objective for getting a degree in nutrition was pretty frivolous – to have a unique credential among personal trainers. Amazingly enough, I intended to make a life of personal training – which didn’t end up panning out. Based on the evidence, I was destined to be glued to the computer rather than hands-on client work at the gym. Anyway, the point is, my underlying goal for the nutrition degree was to just get it over-with, so I could be more marketable than most personal trainers. In contrast to my lackadaisical waltz (& mediocre performance) through the undergrad, I got straight-A’s through my master’s degree in nutrition because I was actually interested in the topics. Timing is important; interest can’t be forced.

The class that shaped my future

The most profound change in my educational enthusiasm occurred during my graduate work in nutrition, in a research methods class. I had a professor in the late 1990′s named Brian Koziol, who had a brief stint as a part-time professor at CSUN. At the time, he was employed at Amgen, and as far as I know, he still is.

Brian Koziol’s passion was research — more specifically, dissecting it. What makes a good study? What makes a not-so-good one? What constitutes a true butcher-job of a study in terms of external and/or internal validity? Koziol actually tried to get the class interested in picking apart the strengths and weaknesses of studies. I’d say he succeeded with a handful of the class, but the majority were sort of lost on the point. In my opinion, he forgot to get across to the class why this exercise was important in the first place.

If I were to teach his class, I’d begin with the philosophy of science, and then move into the continuum of evidence. Heck, I’d even burden the class with the philosophy of evidence. I’d sincerely ask the class if they believed that science as an underlying philosophy is important, and why. I’d also belabor the elements of scientific thought, and why this is important in the battle against the bullshit products and protocols that pervade the health & fitness industry.

Perhaps not too surprisingly for those who’ve followed my work, Koziol’s research methods class was my single greatest career influence. There were other catalysts (such as the work of Lyle McDonald) that led to the materialization of my research review, but Koziol’s class – which I took more than a decade ago – was the foundation for that.

Notes for the students

Back to my presentation at the career symposium… Each year it forces me to introspect upon what makes me tick, and what makes my career something I happen to be very happy with. Here’s a relay of some of the important bits of advice I threw at the students:

  • Come to grips with what it is you’re absolutely nuts about (not just vaguely interested in). This is what you should be doing as a career.  Try to recall the last time you did an exceptional job at something you couldn’t give half a crap about, and my point becomes clear.
  • It’s ideal to match your interests with your talents, but skill can always be developed; whereas the desire for a particular job cannot always be developed. Do not pursue a career merely because you think it’s a prudent or safe choice. This naive capitulation has been the kiss of death for many.
  • There’s a market for EVERYTHING, but just be aware of how large or small that market is, in order to estimate your earning potential.
  • Experience builds confidence. Don’t expect to be polished right off the bat. Get in the trenches, get dirty, but try to learn as much as you can from the mistakes of your predecessors. The career series I wrote to kick off this blog should give anyone contemplating a fitness career ample food for thought.
  • Your perception of success will change over time.  Your interests & goals will evolve over time. It’s crucially important to be aware of this metamorphosis and act upon it regularly. We get so caught up in the mind-numbing routine of our work week, that it’s easy to lose touch with where we are, versus the direction we need to be moving. The solution? Do a “blank sheet day” at least once a year. This is an idea I got from a highly successful friend of mine, Daryl Wizelman. What you do is block out an entire day once a year to be by yourself. The whole day – with no one around you. I know that this is a horrifying concept, but bear with me.  Get a paper notebook (not something with internet access), and get yourself out into a secluded area  (a park, abandoned wherehouse, etc – whatever it takes to be alone), and VERY SPECIFICALLY write out your dream lifestyle. I’m not talking about compromising here, I’m talking about having the balls to actually fantasize for a moment about what type of life would make you truly happy. This obviously is gonna vary, but in all cases, be honest with yourself about what it is. Answer questions like: Where do you want to live? What do you want to spend your day doing? How many days a week do you want to work? What kind of life & career have you always dreamed about having, and what SPECIFIC steps can you take to get there if you’re not there yet? What sacrifices do you need to make? How do you want to give back charitably once you get the means to do so? How do you want to be remembered? Then, review your plan regularly through the year. I’ve been doing this “blank sheet day” exercise annually for the last 3 years now, and suffice it to say that I can’t even begin to tell you how much it has helped me personally. I’m also consistently entertained by how much my goals & general perspective changes.
  • If you are enjoying the process of pursuing your goals and crafting your career, you can consider yourself successful. This principle is hammered so very eloquently by Robert Hastings in his essay called The Station. As cliche as it sounds, the destination is far less important – and certainly far less real - than the journey. Life is merely a succession of days. What you do with each day determines the kind of life you’ll create, and ultimately the kind of life you’ll look back on.

It’s okay to disagree.

2010 March 13
by Alan Aragon

Disagreement leads to investigation, investigation leads to learning.

The photo above was taken by a friend of mine with a great sense of humor (note this post here). He knows full-well that I’m not a proponent of supplemental BCAA on top of a preexistent high-protein diet typical of the fitness population, so this pic is an inside joke for those who are new to my writings.

One of the things that people miss is that most professionals in a given field tend to agree on the majority of fundamental principles. For example, I may disagree with some folks on the amount of fructose that can safely be incorporated into a diet, but that probably represents 10% of the whole picture, 90% of which I’d probably be preaching to the choir.

Another example is supplemental BCAA. There are some highly intelligent, well-educated folks that disagree with me on the lack of justification of its use under the aforementioned conditions. Guess what? That’s okay. Disagreement occurs throughout the lowest to the highest levels of research & practice. If there was no dissent, there would be little motivation to push forward with investigations that can yield more definitive answers to the grey areas of knowledge.

While I might disagree with some folks about the use of supplemental BCAAs amidst abundant high-quality dietary protein, I probably agree with them on the majority of all other topics. In any case, I took an in-depth look at the applications & limitations of BCAA supplementation in the latest issue of AARR.

One more plug — I wrote an article for wannabebig.com on the controversial issue of how much protein the body can use per meal (click here). Let me just add that Daniel Clough of AtLarge Nutrition was exceptionally great to work with – one of the coolest guys in the biz.

If you disagree with anything I write, that’s fine with me. What’s the worst that can come from debating a topic? One or both sides acquire new knowledge…that’s a good thing.

A retrospective of the fructose alarmism debate.

2010 February 19
by Alan Aragon

Three hundred…

After 300 comments and counting, it’s safe to agree with Nigel Kinbrum that my recent critique of Dr. Robert Lustig’s fructose lecture “has caused a bit of a stir in the nutritional blogosphere.” The intense debate (& discussion) that ensued inspired me to re-cap some things I feel were most interesting. There was plenty of learning to be had on both sides of the fence. Here are the highlights as I see them:

  • Dr. Lustig showed up, to the excitement and anticipation of all, including me. He went 3 rounds with me, which was actually more than I expected.
  • In round one, he defended his position using  survey data that was contrary to the ERS/USDA data, which is well and good. I don’t disagree that survey data in general is pretty messy and equivocal, not to mention, incapable of establishing causal relationships. He then repeated his claim that the Japanese diet contains no fructose outside of fruit. Perhaps due to hasty error, he says, “That is what we are talking about here; added dietary sugars; not endogenous ones.” I’m going to assume he meant to say intrinsic sugars, not endogenous sugars.  In any case, this idea that the Japanese do not add sugar to their diets is completely false – regardless of which regional or traditional aspect of Japan you’re talking about (this actually was never specified). He also mentioned the revised recommendations of the American Heart Association (AHA), which David Gillespie follows up on towards the end of the discussion, where the full picture is omitted until I post it up (I’ll get to that).
  • In my rebuttal to Lustig’s initial comment, I first point out the limitations of epidemiological data, as well as Lustig’s neglect of the numerous factors that have contributed to a reduction in energy expenditure, such as, “an increase in sedentary occupations; an increase in two-income households and single-parent households; transportation and infrastructure changes that discourage physical activity; a decrease in PE classes and extracurricular sports programs in schools; an increase in sedentary forms of entertainment (i.e. TV/movie viewing, video games, internet, etc.); demographic changes (i.e. aging population, immigration, etc.); a decrease in food costs with increase in food availability and changes in food consumption patterns” (study here).  I  finish off by pointing out the error of the claim regarding the Japanese diet, and mention Lustig’s omission of giving concrete numbers in his lecture regarding the dose-dependent safety of fructose in the diet.
  • Lustig’s 2nd round defense was merely a cut/paste of the abstract of a 31 year-old epidemiological study showing that, “a high fat, high simple carbohydrate, low complex carbohydrate diet and/or reduced levels of physical activity increase risk of diabetes.” My rebuttal to this was simple. I pointed out how Lustig was not only using uncontrolled data to support his stance, but he was being selective about what the observational data showed. I used the study he posted plus two more recent studies to show the common thread among each of them: an increase in fat, an increase in sugar, and a decrease in physical activity was associated with adverse health effects. Clearly, it’s incorrect to selectively scapegoat the single factor of your personal choice.
  • In Lustig’s final defense, he first cites as study wherein roughly 150 grams of fructose (the equivalent of 6-7 cans of non-diet soda), increased visceral adiposity and reduced insulin sensitivity in overweight & obese subjects. Does this surprise anyone? The study he cited used a fructose dose that’s 3 times the average American intake. He then goes on to cite rodent research despite his acknowledgement of my demand for human interventions using non-stratospheric doses of fructose. All this, after my multiple citations of human research showing the contrary.  To top everything off, Lustig cited his Youtube popularity as a basis of accuracy and credibility. That was not a good move. My rebuttal to Lustig’s final comment is right here.
  • I emailed Lustig, thanking him for the discussion, and he responded by preaching to me more of his gospel. I politely asked that he take his argument back to the blog since the purpose of the whole discussion in the first place is to educate the public. He would have none of that, quipping that “real scientists” don’t go tit-for-tat on blogs, they go to journal clubs to discuss research with other “real scientists.”  If his case was as strong as he thinks it was, he wouldn’t have gotten embarrassed by the opposition.
  • As I mentioned in response to a straight-shooting article by Martin Berkhan, Lustig probably has more education and native intelligence than he knows what to do with. However, as he demonstrated, you can be the most brilliant guy in the world & still find yourself fumbling over groundless claims.
  • Comments by Ryan Zielonka (here), RG (here), DSD  (here), and Rob (here) illustrate the regional heterogeneity of the Japanese diet, and how it can’t be simply pegged as fructose-free aside from the fruit intake.
  • Fred Hahn brought his classic carbophobic flair (here), which was well-rebutted by Mike Howard (here) and Leigh Peele (here).
  • Ganine asked the question of whether or not HFCS has different metabolic effects than regular sugar (sucrose). James Krieger came in with a follow-up response stating that, “The only practical difference between sucrose and HFCS is in the bonding. The glucose & fructose in HFCS is mainly free and unbonded, while it is bonded in sucrose. However, this makes no *meaningful* difference in regards to metabolism in the body. The bonds in sucrose are quickly broken when sucrose hits the acid environment of the stomach. This means that once sucrose hits the stomach, it’s no different from HFCS. Once you get to the small intestine, metabolism is *exactly* the same. This *little bit of difference* does not lead to the problems Dr. Lustig talks about. The fact is, HFCS and sucrose are identical as far as your body is concerned. The difference in bonding wouldn’t make a shred of difference in regards to your health.”
  • Speaking of James Krieger, I’d like to direct anyone interested in fructose metabolism to this fine tutorial here.
  • In response to Mike K’s advocacy of food avoidance, I posted research indicating an association between inflexible, all-or-nothing eating habits and adverse conditions. To quote Stewart et al, “The study found that individuals who engage in rigid dieting strategies reported symptoms of an eating disorder, mood disturbances, and excessive concern with body size/shape. In contrast, flexible dieting strategies were not highly associated with BMI, eating disorder symptoms, mood disturbances, or concerns with body size.”
  • Here’s a quote from a similar study by Smith et al: “Subjects were administered questionnaires measuring dietary restraint, overeating, depression and anxiety. Measurements of height and weight were also obtained in order to calculate BMI. Canonical correlation was performed to evaluate the relationship of dietary restraint variables with overeating variables, body mass, depression and anxiety. The strongest canonical correlation (r=0.65) was the relationship between flexible dieting and the absence of overeating, lower body mass and lower levels of depression and anxiety.”
  • Indeed, correlation doesn’t automatically equal causation, but the two studies I cited above build a far better case than the baseless assumptions of folks who assert their dietary perfectionism onto the world around them.
  • Ardent sugarphobe David Gillespie presented some very engaging arguments. However, he ignored all other posters, as well as the evidence I presented. He correctly pointed out that John White’s HFCS article contained a citation of research that did not support the point he was making (good catch, David!). However, he went on to dismiss reams of data on the grounds of funding source. He also incorrectly accused a study of being funded by the Coca Cola company, when in fact, Coke funded the travel expenses after the study was already complete. As James pointed out, the study was funded by a scholarship, two fellowships, and a grant from the Canadian government. Beyond that, studies should not be judged solely on funding source; the weight of their scrutiny should rest on their quality of design.
  • David responded by citing the AHA’s recommendations, which I’ll quote him as saying, “Of particular note is their final recommendation that an adult male should consume no more than 144 calories (38 g) per day in added sugars (which would be 19g of fructose).” The problem with this is that it omits the range of doses the AHA listed for various populations, which went as high as 19 teaspoons of sugar per day for active males, which is double the figure that David emphasized. Of course, it’s convenient to leave out the higher end when you’re building a case that’s biased toward sugar avoidance. Go here to see my response to this, which includes a screen shot of the chart in the AHA paper.
  • In my final rebuttal to David, I explain what discretionary calories are, and how their intended use further supports the point I made in my original article. To quote my response, “The discretionary allotment for an active male is 512 kcal, and a sedentary one is 290 kcal. The average of this is 401 kcal. Technically, it wouldn’t violate the AHA’s recommendations if someone’s entire discretionary kcals came from sugar, which in the case of 401 kcals is about 100g, which equates to 50g fructose, which brings us right back to the exact number I listed as the upper safe limit in my original article.”
  • An honorable mention is deserved for the most epic comment, by Jamie Hale.

I want to give sincere thanks everyone who contributed to this discussion. To end off, I encourage anyone interested to check out the following scientific reviews for further information on the topic of fructose:

The JP Fitness Summit: It doesn’t get any bro-er than this.

2010 February 12
by Alan Aragon

It’s goin’ down like this.

Right after the completion of my MonaVie vs Two-Buck Chuck article, a wise friend of mine told me that I need to shorten my blog posts, post more often, and save the technical stuff for my research review. She feels that people visit my blog for human-interest purposes more than to get a physiology lecture. Obviously, she underestimates the nerdiness of my readership. :)

In any case, I’ll run with her advice for a quick second and alert y’all to the JP Fitness Summit in Kansas City, MO on May 14-16. I’m being 100% sincere when telling you that this is easily one of the most fun & gratifying events on my calendar. I get to wear the hat of a teacher during my presentation, a student during the lectures of the other presenters, and a regular guy when it comes to relaxing & stuffing my face with greasy food and beverages of varying fructose content.

Aside from the awesomeness of meeting online clients and the wonderful  ol’ core group of JP Fitness forum regulars, I’m particularly excited about the speaker line-up.

  • Ryan Zielonka has been a close friend of mine for years now, and it’s great to see his talents recognized with a spot on the Summit podium. Ryan attended last year’s summit, so he knows what he’s in for this time, and I’m sure he’ll deliver.
  • Bret Contreras is someone I don’t know personally, but instantly admire for a couple of reasons. For one, he created the video below. Perhaps most importantly, this guy is dead-serious about perfecting the structure & function of the glutes. I’d go as far as saying that he is arguably the world’s foremost butt-spert. Check out this product he developed. I can’t wait to see the kind of hurtin’ he’s gonna put on the brave Summit attendees during his workshop.
  • Nick Tumminello is another guy who I haven’t met yet. I’ve only heard good things about Nick from industry folks & enthusiasts alike. Given that the online community never pulls punches with its honesty, that’s saying a lot. Nick and I are both contributing editors to Men’s Health magazine, so you know this guy keeps it classy.
  • Lou (Fricking) Schuler! Lou is my inspiration to tell it like it is, and get the point across clearly by any means necessary. Even if it means dropping an occasional F-bomb now and then. There is never a dull moment with Lou, on or off the speaking stage. He has been a Summit favorite since its inception, and the rep is well-deserved. I learn something new from Lou with every conversation.
  • Alan Aragon gives continuing education lectures to dietitians and physicians, on the seldom occasions he lectures at all. He seems to be a smug prick, and I don’t really like the cut of his jib, but I’ll give him a fighting chance at pulling off a decent showing.

The bitter truth about fructose alarmism.

2010 January 29
by Alan Aragon

 

Dr. Robert Lustig, professor of pediatrics at the University of California at San Francisco, is the star of the video above. While he presents some material that’s scientifically sound, he also makes enough errors to warrant a healthy dose of criticism. There’s a ton of material he goes over, so instead of writing a multi-chapter opus, I’ll discuss the aspects that I feel are the most relevant and interesting.

Bravo, Doc

Lustig’s delivery is clear, confident, charismatic, and engaging overall. I’m sure many would think that his style is annoyingly smug and preachy, but I find it entertaining. This is a good thing, since the video is about 90 minutes long. Amidst the  folly that prompted this post, he offers a few good observations.

First off, he makes a valid point that the public health movement against dietary fat that started in the early 1980′s was a grandiose failure. The climb in obesity to epidemic proportions over the last 30 years is plenty of evidence for this. It was also accurate of him to cite the significant increase in overall caloric consumption over this same time period. Furthermore, he shows an interesting progression of Coca-Cola’s 6.5 oz bottle in 1915 to the  20 oz bottle of the modern day.

Lustig acknowledges the First Law of Thermodynamics as it applies to changes in bodyweight. He attacks the vague expression that “a calorie is a calorie” by pointing out that different nutrients impart different physiological effects and have different roles within the body. His concluding recommendations included kicking out liquid calories except milk, which is generally a good strategy for children. Okay, so far so good. But what does he say that’s so misleading? Let’s take a look.

Boooo, Doc

While Lustig correctly points out that the nation’s overall caloric consumption has increased, he proceeds to blame carbohydrates as being the primary constituent. The thing is, he uses data spanning from 1989-1995 on children aged 2-17. Survey data is far from the gold standard of evidence, but if you’re gonna cite it, you might as well go with something more recent that includes adults.

Here’s the latest from the USDA Economic Research Service (ERS), which tracked the percent of total daily calories of the range of food groups from 1970-2007. The actual spreadsheet of the following figures can be downloaded here, click on the “Percents” tab at the bottom (note that these figures are updated regularly by the ERS, so the version you download may be different from what’s reported here) [1]:

  • Meats, eggs, and nut kcals decreased 4%.
  • Dairy kcals decreased 3%.
  • Percentage of fruit kcals stayed the same.
  • Percentage of vegetable kcals stayed the same.
  • Flour and cereal product kcals increased 3%.
  • Added fat kcals are up 7%,
  • Added sugars kcals decreased 1%
  • Total energy intake in 1970 averaged 2172 kcal. By 2007 this hiked up to 2775 kcal, a 603 kcal increase.

Taking a hard look at the data above, it appears that the rise in obesity is due in large part to an increase in caloric intake in general, rather than an increase in added sugars in particular.

Lustig insufficiently addresses the ‘energy out’ side of the equation. According to the research, it’s possible that over the last couple of decades, we’ve become more sedentary. King and colleagues recently compared the physical activity data in the National Health & Nutrition Examination Survey (NHANES) from 1988-1994 with the NHANES data from 2001-2006, and found a 10% decrease [2]. From a personal observation standpoint, that figure seems conservative (internet surfing for hours after your desk job shift, anyone?). It’s safe to say that all 603 extra daily calories have been landing in the nation’s collective adipose depot.

It’s also safe to say that all this finger-pointing at carbohydrate is just as silly as the finger-pointing toward fat in the ’80′s. Lustig takes the scapegoating of carbohydrate up a notch by singling out fructose. Perhaps the most passionate point he makes throughout the lecture is that fructose is a poison. Well, that’s just what we need in this day and age – obsessive alarmism over a single macronutrient subtype rather than an aerial view of the bigger picture.

Fructose is evil, context be damned

So, is fructose really the poison it’s painted to be? The answer is not an absolute yes or no; the evilness of fructose depends completely on dosage and context. A recurrent error in Lustig’s lecture is his omission of specifying the dosage and context of his claims. A point he hammers throughout his talk is that unlike glucose, fructose does not elicit an insulin (& leptin) response, and thus does not blunt appetite. This is why fructose supposedly leads to overeating and obesity.

Hold on a second…Lustig is forgetting that most fructose in both the commercial and natural domain has an equal amount of glucose attached to it. You’d have to go out of your way to obtain fructose without the accompanying glucose. Sucrose is half fructose and half glucose. High-fructose corn syrup (HFCS) is nearly identical to sucrose in structure and function. Here’s the point I’m getting at: contrary to Lustig’s contentions, both of these compounds have substantial research showing not just their ability to elicit an insulin response, but also their suppressive effect on appetite [3-6].

But wait, there’s more. In studies directly comparing the effect of fructose and glucose preloads on subsequent food intake, one showed no difference [7], while the majority have shown the fructose preload resulting in lesser food intake than the glucose preload [8-10]. A recent review of the literature on fructose’s effect on satiety found no compelling case for the idea that fructose is less satiating than glucose, or that HFCS is less satiating than sucrose [11]. So much for Lustig’s repeated assertion that fructose and fructose-containing sugars increase subsequent food intake. I suppose it’s easier to sensationalize claims based on rodent data.

In the single human study I’m aware of that linked fructose to a greater next-day appetite in a subset of the subjects, 30% of total daily energy intake was in the form of free fructose [12]. This amounts to 135 grams, which is the equivalent of 6-7 nondiet soft drinks. Is it really that groundbreaking to think that polishing off a half-dozen soft drinks per day is not a good idea? Demonizing fructose without mentioning the dose-dependent nature of its effects is intellectually dishonest. Like anything else, fructose consumed in gross chronic excess can lead to problems, while moderate amounts are neutral, and in some cases beneficial [13-15].

I’m obviously not in favor of replacing anyone’s daily fluid intake with soft drinks, but I can already see a number of straw man arguments headed my way. This is because people have a tendency to think in either-or terms that strictly involve extremes. I’ll quote an elegant review by independent researcher John White that echoes my thoughts [16]:

Although examples of pure fructose causing metabolicupset at high concentrations abound, especially when fed asthe sole carbohydrate source, there is no evidence that thecommon fructose-glucose sweeteners do the same. Thus, studies using extreme carbohydrate diets may be useful for probing biochemical pathways, but they have no relevance to the human diet or to current consumption.

Atkins, Japan, & alcohol – oh my!

One of Lustig’s opening assertions is that The Atkins diet and the Japanese diet share one thing in common: the absence of fructose. This is flat-out false because it implies that the Japanese don’t eat fruit. On the contrary, bananas, grapefruits, Mandarin oranges, apples, grapes, watermelons, pears, persimmons, peaches, and strawberries are significant staples of the Japanese diet [17]. Lustig’s claim also implies that the Japanese do not consume desserts or sauces that contain added sucrose. This is false as well.

Another oversimplification Lustig makes is that fructose is “ethanol without the buzz,” and that fructose is toxic to the liver. This once again helps me illustrate my point that even in the case of alcoholic beverages, their risk or benefit to health is dose-dependent. Just like his extremist  treatment of fructose, Lustig bases his case on the effect of chronic isolated ethanol consumption in large doses. It’s easy to examine ethanol out of its normal context within beverages such as wine, because then you can conveniently ignore the evidence indicating its potential health benefits when consumed in moderation [18].

Partial redemption

Towards the end of Lustig’s lecture, he mentions that fructose within fruit is okay because its effect is neutralized by the fiber content. To a degree, this is a valid claim. However, in building this stance, he uses sugarcane to illustrate just how fiber-dominant natural sources of fructose are, and this is the exception rather than the rule. He claimed that, “Wherever there’s fructose in nature, there’s way more fiber.” That statement is far from universally true. Drawing a few common examples from the major fruits consumed in Japan, a midsize banana contains roughly 27 total grams of carbohydrate, 7 grams of fructose and 3 grams of fiber. A midsize apple contains 25 total grams of carbohydrate, 12 grams of fructose and 4 grams of fiber. Two cups of strawberries contains 24 total grams of carbohydrate, 4 grams of fructose, and 6 grams of fiber.

I would add that fiber is only one of the numerous phytochemicals in fruit that impart health benefits. Thus, it’s not quite as simple as saying that fructose is evil, but once you take it with fiber, you’ve conquered the Dark Side.

Summing up

I have a great deal of respect for Lustig’s professional accomplishments, and I share his concern for the nation’s penchant for sitting around and overconsuming food and beverages of all sorts. However, I disagree (as does the bulk of the research) with his myopic, militant focus on fructose avoidance. He’s missing the forest while barking up a single tree.

So, what’s the upper safe limit of fructose per day (all sources considered)? Again, this depends on a number of variables, not the least of which are an individual’s physical activity level and lean body mass. Currently in the literature is a liberal camp reporting that fructose intakes up to 90 grams per day have a beneficial effect on HbA(1c), and  no significant effects are seen for fasting triacylglycerol or body weight with intakes up to 100 grams per day in adults [15]. The conservative camp suggests that the safe range is much less than this; roughly 25-40 grams per day [19].  Figuring that both sides are biased, the middle figure between the two camps is roughly 50 grams for active adults.

Although the tendency is to get hung up on the trivial minutia of an exact gram amount, it’s not possible to issue a universal number because individual circumstances vary widely (this is a concept that baffles anti-fructose absolutists). The big picture solution is in managing total caloric balance with a predominance of minimally refined foods and sufficient physical activity. Pointing the finger at fructose while dismissing dosage and context is like saying that exercise should be avoided because it makes you fat and injured by spiking your appetite and hurting your joints.

MonaVie versus Two-Buck Chuck

2009 December 12
by Alan Aragon

 

This post is inspired by an article called Berried in hope: a scientific look at the implications of exotic fruit juice marketing, the main article in the May 2008 issue of AARR. I find this topic interesting because it’s so highly misunderstood by so many. Not to mention, big bucks are flowing through an industry that makes a lot of promises – but does it fulfill them?

Meet the competitors

Charles Shaw wine is also known colloquially as Two-Buck Chuck. As its moniker implies, Charles Shaw runs 2 to 4 bucks a bottle. It’s sold exclusively through Trader Joe’s grocery stores, which are numerous throughout the US. Despite their dirt-cheap price, the 2002 shiraz and  2005 chardonnay have topped the field in prestigious wine competitions. Although Charles Shaw is available in a variety of types of reds, I’ll refer to red wine as a general category.

MonaVie is a direct sales-based company whose namesake beverage is a blend of juices featuring the acai berry. Arguably, no other fruit has garnered acai’s level of media hype. Acai has become a household name, due in part to best-selling author Dr. Nicholas Perricone proclaiming it to be the #1 superfood. As of this posting, MonaVie is ranked #18 on Inc. Magazine’s top 5000  private companies in the US, with 2009 revenues totalling $854.9 million. This is about double the annual revenue of the entire catalog of Charles Shaw’s parent company, Bronco Wine CO. Monavie’s product line has expanded with variations of the original juice blend, but each product’s key ingredient is the acai fruit.

Antioxidant capacity

The primary selling point of MonaVie is the antioxidant capacity of its acai berry content. The overhyped importance of antioxidant products is a separate topic altogether. Here, we’ll focus on how strong the antioxidant claim is. On MonaVie’s website, they cite a 2006 study showing that a freeze-dried acai powder has the highest oxygen radical absorbance capacity (ORAC) of any food tested to date [1]. Since ORAC is a measure of antioxidant effect, MonaVie proponents use this research to support the claim that the acai berry is the king of the antioxidants. 

Here’s what a lot of people miss: ORAC is not the only way to assess antioxidant capacity.

A subsequent study using a more comprehensive assessment panel on 10 commonly consumed polyphenol-rich drinks yielded some interesting results [2]. In addition to ORAC, 3 other antioxidant tests were administered: trolox equivalent antioxidant capacity (TEAC), free radical scavenging capacity by 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP). In addition to the 4 antioxidant capacity tests, they measured inhibition of low-density lipoprotein (LDL) oxidation, and total polyphenol content by gallic acid equivalents (GAEs). Each of the 6 tests was equally factored into determining overall antioxidant potency. Here’s how the beverages ranked:*

  1. Pomegranate juice
  2. Red wine
  3. Concord grape juice
  4. Blueberry juice
  5. Blackberry juice
  6. Acai juice
  7. Cranberry juice
  8. Orange juice
  9. Iced tea (green, black, & white tea collectively)
  10. Apple juice

*Caution is advised against the tendency to judge foods based on a single parameter such as antioxidation. Many people will automatically perceive the above list as a good-to-bad continuum. Don’t fall into that trap; all foods have unique nutritional benefits aside from their antioxidant effects. 

When acai juice was put through a more thorough battery of testing, it ended up with a humble ranking at #6, while red wine came dangerously close to the top spot held by pomegranate juice. As this study indicates, the claim that acai berry is unquestionably the most potent antioxidant is false.  For those itching to cry “foul” because MonaVie wasn’t used in this study, I’ll quote the researchers who were already a step ahead of that concern:

“…the acai juices in Figure 1 and Tables 1 and 2 did not include Mona Vie, the premier acai blend, because it is a blend of acai and 18 other fruit juices. The Mona Vie data show the polyphenol and antioxidant index to be in the same range as for the acai juices reported or in the midrange for all beverages analyzed in this study.”

Chalk one up for Two-Buck Chuck.

Bang for the buck

Charles Shaw wine is famous for its low price (2-4 bucks a bottle). In contrast, MonaVie is famous for being about $40 per bottle. Imagine that, you can get 10-20 bottles of Charles Shaw for the price of 1 bottle of MonaVie. Sounds like a party. You can drink a ton of MonaVie, and the only buzz you’ll get is your phone vibrating with your accountant calling to say, “You’re KILLING me Larry!”  Chalk up another point for Charles.

The obnoxiousness factor

Charles Shaw just sits quietly on the shelves before getting snatched up by customers who voluntarily seek it out. MonaVie has independent sales reps that nag you to attend a “tasting” where you’re politely obligated to become either a MonaVie distributor or simply a customer. This is multilevel marketing, where you’ll inevitably mix family and friends with business (not a good idea). Give good ol’ Chuck another point, and a final nod for the win.

Conversations with a bro: animated edition

2009 November 29
by Alan Aragon

 AARR subscriber David Miklas created this endearing video series over the Thanksgiving weekend. Apparently the turkey, stuffing, mashed potatoes, gravy, and pumpkin pie put him in good spirits. Note the gestures, note the comic timing. The fact that I’m talking to a jock just kills me, as does my radical tan. Many of the quotes take me down memory lane, since they were plucked from the glory days of schooling the bros on the message boards. Warning: this series is best watched under the influence of holiday cheer…enjoy.

 




RECENT UPDATE: David once again shows his video editing and scriptwriting mastery in the lastest 2 intallments above. Speaking of Anaconda, check out JC Deen’s no-BS article on the overhyped product.

Wisdom & wisecracks

2009 November 22
by Alan Aragon

The following is a collection of things I’ve blabbered off in message boards and elsewhere. I got the idea of posting this from the illustrious Emma-Leigh, a fellow moderator at bodybuilding.com who stuck a similar collection of my quotes at the top of the female bodybuilding forum. If you’re easily offended, please stop reading right here. If not, enjoy the tidbits…

  • The majority of health nuts will spend $100′s a month on useless supplements, but won’t spend a dime on actually educating themselves on the facts about the body.
  • I love it when I hear folks say that human adults weren’t meant to consume milk, much less the milk derived from a different animal species. Are you kidding me? So who gets to decide which parts of the cow we should consume? Let me get this straight–we can eat the cow’s muscles, but not the milk that laid the foundation for the growth of those same muscles? Huh? The logic is just too rock-solid for me.
  • Folks who carry the torch against milk consumption typically will have some degree of allergy or digestive intolerance to it, and they take the liberty to project their personal problems onto the world around them.  Go frolick in an organic wheatgrass field and spare us your self-righteous noise.
  • Keep your eyes on YOU. It’s fine to get inspired by others’ physiques, but you have to set your own personal standards. People tend to fixate on their weaknesses, while at the same time obsess over the strengths of others. That’s a surefire way to stay eternally frustrated. It’s a healthier approach to acknowledge your own strengths, and use them as benchmarks by which to bring up your weaknesses. Learn to give yourself a pat on the back for the improvements you make. Keep your eyes on YOU, don’t let the achievements of others dictate your obsessions.
  • March to your own beat. Everyone has advice to give, and it’s important to listen, but ultimately, you have to adapt and mold all advice to your own sensibilities. Although it’s not always easy, I try not to be inflexibly dogmatic about what I teach. In many cases, what’s known pales in comparison to the sprawling expanse of the unknown. Over time, you’ll get to know your body better than anyone else, and what some might sell as natural laws should really only be ideas or options to consider.
  • Training and nutritional programs pulled from the “experts” shouldn’t always be followed to the letter, especially for advanced trainees. Beginners without a clue may need to follow a script with zero deviation, since the alternative might be tripping over their own feet. But with more advanced trainees who have a more highly developed sense of individual response, there should always be a margin for personal intervention and adjustment. The best programs out there are at best good guidelines from which to morph better stuff for the individual situation.
  • Question fitness advice given to you by others. “Why” is one of the most powerful words you can put in your vocabulary. Investigating the reasoning behind the advice will often reveal that the answer is “just because”, rendering the advice anywhere from helpful, to dangerous, to just a plain waste of time and resources. I encourage my clients, students, and colleagues to question everyone’s advice, including mine. I firmly believe that the better you can sharpen your thinking, the better you can continue to sharpen your physique.
  • Scientific research is not bias-free. It’s not free of financial interests. It’s not free of study design flaws, and it’s not perfect. However, it’s the best tool that we have for getting closer to understanding the way the body works, the way that nature works. As imperfect as research is, it beats the hell out of hearsay and gym dogma.
  • Many folks into fitness & bodybuilding have this unproductive tendency to think in black & white extremes. They’ll scapegoat certain foods, while glorifying the magic bullets. They rarely see the integration of the various components that comprise the big picture.
  • Maintenance of a given level of progress is indeed a legitimate goal. In fact, people should consciously build plateau phases into their programs. Everyone hates to hear this, but the plateau phases should get progressively longer. When you step back and think about it, isn’t the ultimate goal a plateau of sorts? It makes good sense to give your body regular practice at maintaining. Everyone is so hell-bent on perpetually pressing forward with their goals, that it actually holds them back.
  • A major training mistake I’ve made in the past – one I think that we’ve all done – was to always go more by the numbers than by the feel, letting the numbers dictate the workout rather than letting the muscles do it. I was overly concerned with the quantitative awareness of load progression, rather than what one of my old training partners called finding the pump. This might be more of a bodybuilding thing than anything else, but people should work up to a point where they are indifferent towards the number stamped on the iron. This is particularly useful during maintenance phases, which are more flexible. Trainees should practice developing a sense of optimal resistance for the given goal of any set, even if you’re completely unaware of the actual weight. Blindfolded sensation-based training, so to speak.
  • Don’t be overly cheap with your time off from training. Athletes’ careers are notorious for being slow-motion train wrecks. There are 3 main ways your body lets you know that you need a break: Fatigue, illness, and injury. Fatigue is a bit more insidious, manifesting itself as persistent stalls or decreases in strength or endurance. Most trainees out there wallow in fatigue most of the time, which is a damn shame. Illness and injury are the classic agents of forced layoffs. The best strategy is to stay not just one, but a few steps ahead by taking a full week off from training – I’m talking don’t even drive near the gym – about every 8th to 12th week.
  • No one’s physique ever fell apart as a result of a periodic week of rest. On the other hand, there are plenty of folks whose great physiques won’t last very long, due to bad shoulders, elbows, and knees.
  • Fad diets and fad diet practices should be avoided (and laughed at). Carbs will send you to hell. Sugar is worse for you than cocaine. Fat is no longer the bad guy, so now it’s time to drink a pint of fish oil after every meal. Protein is your savior, eat as much of it as you can. If it’s isolated from food and put in a pill, it’s GOTTA be better for bodybuilding. C’mon now. A mix of patience and realistic progress expectations is the best cure for the compulsion to adopt fad practices or try fad diets.
  • Stop splitting hairs over the rules. The beauty of food is that, unlike drugs, its physiological effects have neither the acuteness nor the magnitude to warrant extreme micro-management, especially when it comes to nutrient timing relative to training. A half an hour difference here or there really isn’t gonna make or break your physique.
  • The first law of nutrient timing is: hitting your daily macronutrient targets is FAR more important than nutrient timing.
  • The second law of nutrient timing is: hitting your daily macronutrient targets is FAR more important than nutrient timing.
  • The fitness & nutrition world is a breeding ground for obsessive-compulsive behavior. The irony is that many things people worry about simply have no impact on results either way, and therefore aren’t worth an ounce of concern.
  • Worrying about how much fat is burned while doing cardio makes as much sense as worrying about how much muscle is built while lifting weights.
  • I eat three whole eggs almost every day of the week, so as far as American Heart Association limits are concerned, I’m blowing past them like Stevie Wonder through a stop sign.
  • Mother Nature winces every time a yolk hits the waste basket.
  • If you have to chew it, it ain’t anabolic. [/sarcasm about postworkout nutrition]
  • The better someone’s genetics are, the more of a dumbf#ck he is.
  • Avoid food avoidance.
