Lyle McDonald

The Keto-man

Lyle McDonald is an athlete, trainer and researcher. He has been involved in athletics since a teenager. His physical endeavors started with triathlon training and then migrated into inline skating – something he continues today with a coach in Salt Lake City, Utah.

McDonald attended UCLA for a degree in Physiological Sciences and continues to devote his life to studying human physiology and the science, art and practice of human performance, muscle gain and fat loss. He generally coaches endurance athletes but also works with powerlifters and bodybuilders. Thousands have been able to use his advice to become great athletes or simply to enjoy a better quality of life through proper physical conditioning.

McDonald is most famous for his publications surrounding ketogenic and cyclic-ketogenic diets. He has written for magazines, numerous Web sites and has published several books. He is currently well-known for his work explaining macronutrient affects on body composition, as well as pioneering research into Bromocriptine as a fat loss agent.

Titled The Ultimate Diet 2.0, to signify a continuation of previous work, McDonald expands on the late Daniel Duchaine’s well-accepted research into carbohydrate cycling and fat loss. Commonly called UD2, it outlines exactly how the body fights back to avoid fat loss and muscle retention while training in a caloric deficit – how the average athlete can achieve superior results in body re-composition. The book explains calorie partitioning, muscular development, hidden metabolic advantages of athletes, optimizing fat metabolism and why stubborn fat is so difficult to lose.

McDonald offers his texts online at BodyRecomposition.com for a reasonable price, considering the obvious effort he puts into his research. The domain also hosts an online discussion forum. Be forewarned, Lyle’s quick and candid wit can easily be taken offensively. This is displayed by viewing his forum posting habits – as well as the forum posts of annoyed members trying to retaliate. McDonald’s online discussions are helpful and constructive with his frequent involvement; though, occasionally tactless in nature. According to his Web site, his philosophy can be summed up by “absorb what is useful.” This is something to put into practice when engaged in his online discussion groups.
