Interesting. While I agree that working out immediately after a huge meal is stupid, I don't see how working out in a fasted state is condusive to making any kind of progress or getting any kind of a quality workout.
Now, as far as meal frequency and eating habbits. Total calories and what those calories are comprised of plays more of a role in fat storage than meal frequency does in my opinion. I agree with him that most bodybuilders don't practice the best offseason eating habbits, the reason many bodybuilders get fat offseason isn't due to eating 8 small meals a day, it is because they go to Taco Bell and McDonalds and stuff themselves until they can't move just for he sake of gaining weight.
I agree that prehistoric people were in better physical condition than the average sedintary American is today. However, science also evolves, and I think today's elite, well-trained athletes, who have a system with respect to training and nutrition would demolish any caveman at just about any physical activity. Tell me a prehistoric man is in better shape than Lance Armstrong......
I do see a lot of where this guy is coming from, and as a Dr, he obviously knows how to use science to back himself up, but I think his ideas would benefit a sedintary person. I think if an elite athlete switched to these methods they would see a SEVERE decline in performance.
Also, I don't know how equated flushing a muscle with lactic acid and getting a burn to GH release. Does curling a 5 lb dumbell 1000 times and getting a burn release a lot of gh?? I know he said he does ets of about 15-8-4....but still, I don't consider going after a burn to be the best way o build functional strength.
