By now, the low-carb diet’s refrain is a familiar one: Bread is bad for you. Fat doesn’t matter. Carbs are the real reason you can’t lose weight. The low-carb universe Dr. Atkins brought into being continues to expand. Low-carb diets, from South Beach to the Zone and beyond, are still the go-to method for weight-loss for millions. These diets’ marketing may differ, but they all share two crucial components: the condemnation of carbs and an emphasis on meat and fat for calories. Even the latest diet trend, the Paleo diet, is–despite its increased focus on (some) whole foods–just another variation on the same carbohydrate fears. In The Low-Carb Fraud, longtime leader in the nutritional science field T. Colin Campbell (author of The China Study and Whole) outlines where (and how) the low-carb proponents get it wrong: where the belief that carbohydrates are bad came from, and why it persists despite all the evidence to the contrary. The foods we misleadingly refer to as carbs aren’t all created equal–and treating them that way has major consequences for our nutritional well-being.
