Fat is it friend or foe? Well if you ask most, including health care professionals, they’ll say foe. It’s time for people to wake up! The current ways of eating aren’t working. Just a few years ago, for the first time in history the top six books on the New York Times Best Seller list, were about the same subject: diets low in carbs, moderate to high protein, high in fibrous carbs (vegetable), and moderate fat. Why is this topic so popular? They work!

One of the biggest reasons protein diets work is the consumption of fat. That is, fat minus the abundance of carbs. Fat has many functions outside of being used as an energy source, and certain fatty acids are essential. Without eating them you’d literally get sick and die.

But how does fat help our diet? Well, fat satiates the appetite, and helps to stop the cravings for sugar. And probably most importantly, fat when combined with a low sugar intake actually aids in burning fat as fuel. That’s right, fat helps burn fat. When fat is restricted, our bodies have a defense mechanism built in through evolution for survival. Our bodies will actually stop using fat as fuel in an effort to preserve our stores for future use.

Bodybuilders have known this for years through trial and error, while dieting for shows, they would reach a certain body fat percentage and suddenly plateau for no apparent reason. We found that by adding fat to the diet like olive oil, or coconut oil, would jump-start the body to burn body fat. It’s not the amount of food you consume that is the problem. It’s the types of food you’re consuming.

Sounds bizarre doesn’t it.

For decades we have been taught that fat is bad for us, carbohydrates are good, and that the key to a healthy weight is eating less and exercising more. Yet with more and more people acting on this advice, we have seen unprecedented epidemics of obesity and diabetes. With seven years of research, Taubes argues persuasively that the problem lies in refined carbohydrates (white flour, sugar, easily digested starches) ?via their dramatic effect on insulin, the hormone that regulates fat accumulation?and that the key to good health is the kind of calories we take in, not the numbers. There are good calories, and bad ones. Taubes traces how the common assumption that carbohydrates are fattening was abandoned in the 1960’s when fat and cholesterol were blamed for heart disease and then?wrongly?were seen as the causes of a host of other maladies, including cancer. He shows us how these unproven hypotheses were emphatically embraced by authorities in nutrition, public health, and clinical medicine, in spite of how well-conceived clinical trials have consistently refuted them. He also documents the dietary trials of carbohydrate-restriction, which consistently show that the fewer carbohydrates we consume, the leaner we will be.

Good Calories Bad Calories is the end of the debate about the foods we consume and their effects on us.
