You have to understand Lyle. He is a certifiable genius when it comes to nutrition and diet. His advice is solid and backed by research, but the diet plans are not necessarily easy. They work, the work very well, and can take you to a leanness not many others can. He is also a jerk, not my words, more of his. You can take his advice and work, but don't argue with him unless you know for damned sure you are right and have some solid evidence.
He is good and solid, and quite entertaining to read or talk to, but his hard edge makes some people stray away. It's too bad really, as everyone can learn a thing or fifty from him.
