The Ultimate Diet 2.0. Advanced Cyclical Dieting for Achieving Super Leanness.

Rate this book
The Ultimate Diet 2.0 represents both a very old and very new approach to the problems of dieting to low bodyfat percentages. It is old in that it builds upon an approach originally developed in the early 80's by bodybuilding guru Dan Duchaine and researcher Michael Zumpano. It is new in that it applies the most cutting edge research to that plan, optimizing it to the greatest degree possible. The Ultimate Diet 2.0 is aimed at advanced dieters and athletes who want to move from ordinary to extraordinary. It will allow dieters to lose 1-1.5 lbs of fat per week with no muscle loss (some dieters gain muscle). It allows athletes to maintain or improve performance while losing bodyfat. It can also be used to gain muscle with minimal bodyfat gains.

Without doubt the best and most comprehensive dieting / training book I've ever read for those seeking to maintain performance whilst getting down to very lean levels. The plan isn't revolutionary for those already familiar with carb cycling diets, but where it really scores highly is with its effectiveness and overlap into real life. For those of a scientific persuasion it goes into very satisfying depth about why carb cycling diets are so effective.

Even if you don't end up following this plan verbatim you'll still learn something about why your current approaches work and if your current "normal' approaches are not working then this provides the next level.

The forum which accompanies this book is a great source of information but pretty hardcore, so take care if you visit. At least make sure you have read the book and followed it to the letter.

Lyle McDonald is probably the wisest (and by "wise" I mean "he knows a shitton of science about nutrition and training) in the fitness community, so his words are basically the truth™. This diet is for sub 12% bodyfat, avarage genetics trainees. It's not for everyone (including myself). But it's grounded in science, well-detailed, and the explanation and underlying principles make a lot of sense.

Good for: people with a lot of muscle that want to diet down under 12%bodyfat.
Not good for: everyone else.

A great read.

Lyle is quite pessimist for most of the book. He uses false claims such as the fact that "hormones such as tesotsterone, thyroid and cortisol are set genetically and cannot be changed". Scientifically, this is completely wrong.

Lyle just might be the nerdiest of the bodybuilding gurus, and I say that as a compliment. This book can be dense at times, but at least it’s only 76 pages. A great resource for getting super cut. Highly recommended.

This author really knows what he's talking about with health & fitness.

Keep in mind this diet is generally for those who are under 20-15% body fat (some say even less). You, of course, can do this diet if you're about it but you don't necessarily need to. He even says in the book (paraphrasing) "Until you get to about 15% any diet will suffice".

Once you hit a lower body fat percentage, check this book out. You won't believe the places it'll take you.

As always Lyle gives great physiology education and breaks down the "why" of methods. One of the smartest men in nutrition. But this is a rather extreme protocol and in my opinion, rather unnecessarily extreme. Will probably "work", but doubt many of these protocols will give superior results to something more realistic with most peoples lifestyles.

Great book, I enjoy Lyle's work, but it's not for everybody. I'd say it's for somebody who deadlifts 500+ lbs, or for someone who competes in bodybuilding profesionally. It be a shame that most recriational lifters would dwell in to the complexity and details of the cycles of training and diet as Lyle proposes instead of focusing on the basics.

Not a diet for the fainthearted or if you're fat. This is the diet for you if you've gotten as lean as possible naturally and want to get even leaner naturally--without losing lean mass.

Another great book from Lyle. Anyone going on a cut, or needs to lose some quick weight, will greatly benefit from this well info contained book.
