You're wrong. Calories are a measure of physiologically usable energy and already take extraction efficiency into account. Even if you had a point, which you don't, the first law of thermodynamics would still apply, and leptin would still provide negative feed back.
- mcphage 7y ago> Even if you had a point, which you don't My point is simple: "calories in" is unmeasurable. It depends on the food you eat, how it's prepared, what else you eat with it, etc. "Calories out" is unmeasurable. It's based on what you do, how you move, how your body processes what you eat, etc. The first law of thermodynamics can apply all the live long day, but the statement "calories in minus calories out" is useless.
