The secret to losing 20 pounds? You have to work with your fat, not against it. You may not love your fat, but your body certainly does. In fact, your body is actually endowed with many self-defense measures to hold on to fat. For instance, fat can use stem cells to regenerate, increase our appetite if it feels threatened, and use bacteria, genetics, and viruses to expand itself.

How can you succeed against odds like that? By using the latest scientific research.

The Secret Life of Fat brings together cutting-edge research with historical perspectives to reveal fat’s true identity: an endocrine organ that, in the right amount, is critical to our health. Sylvia Tara  expertly illustrates the complex role genetics, hormones, diet, exercise, and history play in our weight, and sets you on the path to beat the bulge once and for all.

Don’t get upset about an expanding waistline, get informed!

NEW: Watch Dr. Sylvia Tara in the NOVA episode, The Truth About Fat. This NOVA episode is very much inspired by The Secret Life of Fat. Listen to a number of the researchers reported on in the book, such as Jeffrey Friedman, Stephen O’Rahilly, Rudolph Leibel, and Ruth Loos.
