<p>For those that don’t know, the concept of trying to lose fat by eating as little fat as possible, for some (or maybe many) puts the body into the mode of trying to preserve fat. So you eat more and more carbs but are still hungry. Eating fat turns off the hunger (try drinking a bottle of olive oil). Two of us on the diet/exercise/health that have lost a lot of weight are using high-fat, low-calorie diets. Going low-fat is fighting brain chemistry.</p>
