Most doctors will tell you that to lose weight you need to burn more calories than you consume. The science writer Gary Taubes would tell you to ignore most doctors. He argues that calories aren’t to blame for America’s obesity problem: hormones are, and so are carbs. To lose weight, Taubes says stay away the low-fat, carb rich foods most diets recommend, and instead eat lots of meat, eggs and fat. It’s a controversial opinion, but Taubes says the proof of science is on his side, and he joins us Thursday to make the case for changing what we think about why we get fat.
