This. I've known a bunch of people who lost a large part of weight (without surgery) and kept it off and they basically turned into different people (more fun though). They restricted their eating, they worked out, often went for hikes etc. But their lifestyle was completely different before and after. They didn't bitch about turning down dessert or things like that. They seemed to actually just be a different person.
