Cutting-edge experts say the “calories in, calories out” philosophy is oversimplified and inadequate.
Quality of calories determines the quantity your body burns or stores, says Robert Lustig, MD, author of the recently published book Fat Chance: Beating the Odds Against Sugar, Processed Foods, Obesity, and Disease. He shares these fascinating examples of how calorie quality affects your weight and health.

you eat a 160-calorie portion of almonds, you absorb only 130 because
some calories are delivered to your intestine, where your gut bacteria
burn them for their own energy source.
