Rarely read so much BS...sorry but there are even professional athletes that are chubby if not outright fat. Google butterbean for example. and you know how hard boxing is i hope. In addition...if we talk FR. ican only say "mirt the moneylender" as a first and there was a fat cleric of torm in one novel series i cant
remember just now.

A successful adverturer gets gold pretty fast and if you spend that on booze and food...gues what happens...you get fat. Even as an adventurer.
