My friend,
Thanks for sharing your results.
According to your self-reported, anecdotal results of your peer group, which use estimations of bodyfat, would I be incorrect in saying your training methods haven't brought anyone under 10% bodyfat? Which is when one's abs will show.
I would also note that Ewalk is presenting an incredibly common set of traits (i.e. a low-fat diet, insufficient caloric intake, insufficient protein, excessive carbohydrates), and one that requires only a bit of nutrition tweaking for him to see results. As the study in the NY Times above mentions, you burn more fat sleeping than with moderate cardio exercise, such as walking.
Just to put this information on the table again, I would contrast your prescription with another path that is available to those looking to lean out. Peer-reviewed clinical trials have shown without doubt that when you compare a low-fat/high-carb diet, such as the one you're prescribing, with a low-carb diet, the low-carb group always loses more weight faster, has better lipid profile, and sustains the weight loss for longer.
This is as reported in the the New England Medical Journal, Lancet, JAMA, Obesity Journal, and BMJ.
Thanks again for sharing you and your friend's results. Ewalk, best of luck.
best,
jason
P.S. Griff, the Starting Strength forum is a great place to look with regards to what's possible with weight gain if you drink your gallon of milk a day. As Justin Lascek, a co-trainer at Wichita Falls Strength Club, has posted: "I still have guys in our gym gain 25 pounds in a little over a month and 40 pounds in about 2.5 months (obviously without steroids). This is not uncommon, as Rip has echoed hundreds of times before."
Granted, he doesn't make the distinction between lean muscle and fat, but still, 25 pounds is 25 pounds.
And as Mr. Rippetoe has posted: "We have a kid that has recently gained 48 pounds in 10 weeks."
My thoughts on Slizzard's reported gains are also echoed on that board, that such weight gain is possible for "adolescents, whose hormonal milieu is such that training them is like training someone on steroids, and underweight novices." I would not be surprised to learn that hormonal profile extends to late teens and very early 20s.
