Stop just stop, any adventurer with any amount of runtime, will not be fat. Its quite simple. And to the op, just because a game or setting has fantasy elements, doesnt mean everything is fantastical. All settings have their own internal logic, and D&D forgotten realms is no exception. Im not trying to fat shame, I would be regarded by some as fat at 120kg. But after a few months of adventuring, I wouldnt be anymore. Now would I be absolutely ripped? Probably not, but fat adventurers stop being fat quite fast. Either that or they give up or die, just as any other adventurer.
