Popular nutritionist Nora Gedgaudas returns with advice that may sound counterintuitive: eat fat to burn fat. In her new book, Primal Fat Burner, she explains the benefits and science behind a ketogenic diet: It switches your metabolism from running on sugars to running on healthy fats. As Gedgaudas reveals, numerous studies in recent years have refuted the previously promoted anti-saturated fat and anti-cholesterol agenda. Now, Gedgaudas explains, science shows that fat isn't a no-no but rather a yes-yes - as long as you know the right kinds of fats to eat. In addition to explaining the science beyond that logic, Gedgaudas also lays out a practical meal plan with recipes - all of which reveals that following a ketogenic diet will lead to consuming fewer calories overall!
