You might also look into Precision Nutrition if you're looking for something with a lot of scientific research put into it. Berardi's website (
Dr. John Berardi, Ph.D.) has an Articles section containing articles with quite a bit of scientific research and information.
In any case, I think that you might be misinterpreting what Alwyn's said about NR4W. He states it's not a fat loss program, meaning that it's not designed as a "let's get this fat off you as quickly as possible." But it IS a program geared to help you learn to use weights, improve your metabolism, and, in the end, change body composition. And fat loss is a part of that. So you
should lose fat on NR4W, just not as quickly as being on a specific Fat Loss program like WSFL.
