Taufiq, thanks for the response.
I checked the book again; the fish oil recommendation is 6 to 10 grams. (Note: See the simplicity of this diet; I don't even have to refer to the book constantly).
Actually, I just work out twice per week on the diet by choice; he actually recommends 2 to 3 sessions per week or 1 every 3 to 4 days.
I don't see why one couldn't do ANY full-body routine of one's choice. Lyle doesn't give any specific recommendations. My program is designed by me. What he does is advise is that training volume be scaled way back from the norm and that split routines be avoided.
The concern with training on the diet is maintaining muscle mass, not gaining. If you can recover from more training, do it. But this diet is aimed at the common, drug-free man with average genetics.
I haven't lost any muscle mass either time. I believe this is because I've been training for over a decade, hardcore. I think if you've trained with heavy (<10 reps most of the time), compound movements and maybe some power-speed work (plyos, speed bench and squat, OLs) for years, you can maintain mass with very-low-calorie diets, sometimes surprisingly low.
Alwyn Cosgrove once referenced a study in which weight-training subjects maintained muscle mass on 800 kcal.
Dan Duchaine once wrote in Muscle Media that it takes a lot of calories to build muscle, but once it's built, it's very easy to maintain, even on low calories.
One advantage I believe I have is that I take Androgel - FOR MEDICINAL PURPOSES. I've been hypogonadal for 7 years. Although I take the medicinal dose of 7.5 grams and have a consistently normal T value (usually 700 to 900 ng/dL), my friends and I DO believe this has helped me maintain my size.
I'm ASSUMING Lyle's recommendations are different because Lyle didn't consult with Chris Shugart or Chad Waterbury or refer to the V-Diet when designing his own strategy.
That's the thing about Lyle; he is VERY bright, highly educated, and FIERCELY independent because of these attributes. He's confident in what he does because of his education, success, and - dare I say - cynicism. The man's been banned from T-forum and the Supertraining listserv.
He take's no shit!
That's why I didn't go over the guidelines of the diet in detail. You ever see someone whose crossed paths with Lyle in print, on the net? He'll wreck you, verbally abuse you!
