I have to say that I'm a little suspicious when I see a book about dieting or health and the author has a string of letters after their name. You never see highly-regarded science authors like Stephen Gould, or Carl Sagan, or Richard Dawkins doing that. In this case, it's just PhD which all too often in these situations seems to stand for PinheaD judged by some of the crap I've seen published accompanied by initials, but in this case, Traci Mann is not only completely legit, she's smart, perspicacious, interesting, and full of useful information and ideas.
She's the leader of the Mann lab at the University of Minnesota, which despite some slightly less than PhD English ("We are a psychology laboratory, under the direction of Dr. Traci Mann, that focues [sic] on how people control their health behaviors" is a going concern, testing out why people behave the way they do vis-à-vis food and dieting and fads.
This book is subtitled "The Science of Weight Loss, the Myth of Willpower, and Why You Should Never Diet Again" and though I've been fortunate enough never to have felt like I had to go on a diet, it's convinced me that I now never will because diets are useless and pointless, serving only to enrich the fat wallets of those fatheads who devise these idiotic and ultimately fruitless schemes.
Why don't diets work? They do in the short term, but with very rare exceptions, people always put the weight back on, and sometimes more than they shed, because your body is predisposed to keep you within a certain weight range, usually of thirty pounds wide, and no matter what you do, you will have a hell of a time in trying to nudge it out of that zone. Biology, advertising, evolution, and other factors are all against you.
That sounds depressing, but the author also offers a better reason not to diet: you are not necessarily unhealthy even if you are deemed 'overweight'. If you're eating healthily and exercising, it doesn't matter what your weight is, because your overall health and life expectancy is going to be the same as those skinny people you seek to emulate so much.
One thing I (and evidently other reviewers) had an issue with is that on the one hand, the author says we have this weight range we tend to stay within which is why dieting is pointless, but on the other hand, there has been a steady increase in average weight among Americans over the last few decades. How is this possible if we have this natural weight baseline that makes it just as hard for us to seriously overeat as it does to shed weight?
The author doesn't seem interested in trying to reconcile this discrepancy in her reporting. Is her 'weight range' shifting upwards, and if so how did this happen and doesn't it overturn her claim that we have an immutable range for our weight, within which we're stuck? Is this weight range very large, which means there is hope for people who do want to try to shed many pounds? Genes do not change this fast, so is there an epigenetic factor in play here? Or is there something wrong with her whole philosophy? It would have been nice to have seen this addressed if not resolved.
The book is in four parts with several subsections: 'Why Diets Fail You', 'Why You Are Better Off Without the Battle', 'How to reach Your Leanest Livable Weight', and 'Your Weight is Really Not the Point'! You can't argue with the science or the clear information and suggestions laid out here. I recommend this book not only because it offers sound advice, but as an interesting read about weight, health, and dieting, and also about psychology and societal pressures.
The book isn't perfect by any means, but it takes a rational approach, and offers simple and scientific advice on what works and what doesn't, and tips on how to make what works, work for you. I've seen a lot of negative reviews of this book complaining about how it talks about your leanest livable weight but never tells you how to calculate it. These reviewers completely missed what had been said earlier! You don't have to calculate anything, because you're already in your weight range. It's your baseline! You can lose a few pounds within your range by eating healthily and exercising, and you're there. No calculation required!
