I read _The Obesity Code_ recently. Makes a good case that obesity is a hormone problem, not really an eating-too-much problem, and can be solved by sharply reducing insulin spikes. tl;dr: Eat fewer meals, don't eat or drink sugar, reduce your carb intake while you're at it, don't fear dietary fat, and don't snack. Eating 1500 calories compressed into one meal will be much better for weight-loss goals than 1500 calories spread out over 3–6 mealtimes.
