No, it's very easy to generalize: an overwhelming majority of people will get fat from overeating, some quicker than others. I'd think your condition is somewhere in the single-digit percentages. I've always been fairly lean – 176/70ish (5'9"/155ish in SU) – a "can eat anything" type, but taking an almost 3-month break from cycling while not reducing food consumption has resulted in a gain of about 8kg/17lbs. (Planning to drop to about 68kg by June).
