That's not what I want a citation for (but, yes - even that is not a trivial assertion, given that there is a nontrivial part of the population, perhaps even 10% who do not get fat regardless of the amount they eat)
I want a citation that "exercise and diet" are enough to convert a fat person to a thin person. Trivially, that's true - just stop feeding person until they starve and almost die, and then feed a little.
But the non-trivial question is: Given person X who is now fat (possibly a result of binge eating, but possibly a result of disease, some kind of pharmaceutical treatment, etc.) - can exercising and reducing intake alone make them thin, without damaging their psyche, without limiting their intellectual potential and mental well being?
There is NO reason to believe that the answer is a simple "yes". People who claim that the answer is definitely yes should be able to back their claims easily, if this is so trivial.
