You're just stating laws of physics though which isn't helpful. The idea behind diets is that your body processes different sources of energy differently. For example, it doesn't process antimatter at all despite its numerous calories. Maybe sugar kicks it into hibernation mode, desiring to engorge everything in site. Maybe ingesting mostly fat causes the body to efficiently start to be able to access excess fat reserves. Maybe it's different for everyone depending on genetics. Stating the laws of thermodynamics to people who are struggling to lose weight or trying to understand how our biology works isnt helpful and just comes across as smug. It's like being a mathematician and looking down on all other fields as just being derived from math.
