For general athletic events this is a good book. It is well written and is a quick and easy read -- you can get the main points out of it in about 30 minutes. The material in it can be useful to anyone that engages in physical activity, not just athletes.
However, it doesn't cover how the glycemic index and carbohydrate consumption can be used to increase lean body mass and decrease body fat. Weight control is dicussed, but there isn't much emphasis on the difference between body fat and muscle. I was looking to understand how I could use the glycemic index to help increase lean body muscle and decrease body fat. The book didn't answer this question for me, but it was enjoyable read regardless.

I found the book to be a good repreive from the Atkins pundits. Atkins seems to link all carbs into two major categories with very little real evidence as to how it effects the insulin levels. Not all carbs are equal and can't be lumped into two simple divisions. Raw carrots do not equal cooked. "....Revolution" has some real answers.
I know people that have lost "10 pounds a week" on Atkins plan without stepping back and examining what that "weight" actually is. Let's do the math. sparing all the physiological details: 3500 calories per pound of body fat times 10lbs, equals about six days of running at ten hours each! (35,000/10 calories per minute/60 = 58 hours of running) Where does the weight come from? Not likely to be fat lose with Atkins plan!
Better to get advice from sources that have the numbers from sound science.
On the flip side, there are some VERY conflicting views presented in the book: "the most important message is that the diet should be low in fat and high in carbohydrates." (quote from page 55). This thought disturbed me, after a year of successfully applying a low-carb lifestyle. With the new edition the above approach was not changed, but rather a new concept was introduced: that of the Glycemic Load. Think of it as a sort of weighted average that combines the quantitative (amount) component of carbs with the measure of the glycemic index (more on the qualitative end), yielding a net measure that should be a better indicator of how healthy a particular food is for you. It's too soon to say whether this Glycemic Load concept has any positive effects at all, but it makes perfect sense. To err on the safe side, I will give the book 4 stars: improved if you compare it with the original edition, but too soon to know whether it will work or not.

A good thing about this book is that it is easy to understand and does not take a lot of effort to implement. It is easy to identify what types of food are better than others (e.g., most vegeatbles rather than bread) and the only effort is to include more of these foods in your diet. If weight loss (and maintenance) is your goal, then lower fat foods should be included in your diet. A good thing aboue this approach is that you don't need to give up "bad" foods, just combine them in moderation with other foods to average things out.
In summary, the book is a very good reference for understanding the concept of GI and making permanant changes in diet. A definite buy!
