Oh please. Energy from food gets stored in fat molecules, that's true, but it's not like physics decrees exact equality in people's outcomes. Someone who digests less efficiently will receive less nutrition from the food they eat. People with tapeworms manage to put on less weight than you'd expect from their diet, for example, and it doesn't seem to be worrying any physicists I've met.
