Lyle McDonald presents a very scientific approach to dieting. The UD 2.0 answers the natural bodybuilders dilemma: how to get lean while keeping most of your muscle. In addition, the weekend carb loads allow for a somewhat normal social life. I have used the UD on several clients in my business with great success. It takes a certain amount of dedication to follow but if you want quick , measurable results without drugs or gimmicks, this is your book!I highly recommend it to any serious trainee.
