For a vast majority of people, obesity is a problem of eating too many kcal. There is no chicken/egg problem for them. The remainder might have some sort of metabolic problem which they should go to the doctor for. There is still no chicken/egg problem there.

Am I missing a group of people who eat exactly the kcal they require, get the nutrients they need and don't have a metabolic problem, but still materialise fat for some reason?




The chicken/egg problem is satiety, not weight. Being fat messes up many small feedback loops, some of which are related to satiety, energy expended, exercise, inflammation or mood.

Breaking those circles is not easy at all. It's closer to rehabilitation and a long process.

Of course reducing intake is a main goal, but then keeping it low is as important.
