Mr. Ivy and Mr. Portman argue with research to back it up that when the meals are eaten and when the muscles are fueled is important. Insulin being the key regulator. Simplifying a lot: Cells can be either insulin sensitive or insulin resistant; Cells can either be muscle cells or fat cells. When the cells are insulin resistant they are not allowed to grow any larger. The key being that we want to 'fuel' the muscle AT THE TIMES that the MUSCLE cell is insulin sensitive. The authors argue that this requires very specific nutrients at very specific times, including Vitamins such as C and E.Apparently this research is ahead of the curve, and dietitians (especially sports dietitians) have failed to recognize the benefits of nutrient timing. As far as the science goes, perhaps there is no argument. A few things the authors fail to address, which I would like to at least see mentioned, is why specifically we need 33% fat in the diet, and more specifically 42%-45% carbs, 30%-33% fat, 25% (thereabouts) protein. All the literature I have read (and admittedly it's not much, although I am a personal trainer, and have read a lot of literature with the certs I have) points to the inability to 'set' the diet because of bioindividuality (45%-75% Carbs, 15%-30% Protein, 10%-30% Fat, I believe are the guidelines). So if that were addressed it would be a 5-Star review. But since it is lacking I can only give it 3 stars.Sample Menu Plans are also included, and commend the authors on not trying to sell the latest and greatest supplement.

This book offers an incredible array of data that cannot be ignored. The premise of the book is that those who consume a carb/supplement drink before, during, and after a workout increase their metabolic rate, sustain energy, blunt cortisol, and increase muscle mass. This book is for both men and women alike. I definitely recommend it to any fitness professional, as well as any lay person. I thoroughly enjoyed the research, which would have taken me months to compile on my own. A definite must for any library of fitness books.
