I came across this guy's work flipping around on the internet researching LBM during weight loss. He seems to have a solid formal education in physiology, is the writer of a number of diet and bodybuilding e-books, and seems up to speed on serious, current research.
One thing I picked up on in one of those articles might explain some of the arguing going on here recently. It gets down to how does insulin broadly effect us as individuals? And once known, the type of diet practically falls into place. Some people are not insulin sensitive, so higher carb diets are just fine. People like that dietitian woman close to me. Others are insulin sensitive, like me, and do better on low carb diets. (This promises to be an interesting relationship!)
He doesn't tackle this merely simplistically, but that's the general riff.
What do you think of his theories? One includes how to lose virtually a pound a day w/o killing yourself. (600-800 calories a day almost all protein, don't exercise.)
What say you?
