” Every meal you ever eat you should be machmir for the largest kezayis and shortest kidei achila, otherwise you risk s bracha livatala by benching.”
That might well make you a glutton. See Ramban to the parshat Kedoshim, which we will be reading the Shabat after Pesach.
As many have pointed out, there is no “meikel” or “machmir” regarding shiurim. A machmir shiur in one area creates kulot in other areas. And anyone who takes all the chumrot is a fool — at least according to Chazal.
