which is your natural body type, ecto or endo?

I weighed 138 on my wedding day, twenty five years ago. My waist was 27 and inseam 30. My jacket size was 32R. Fast foward to today. I weigh 220, waist 39, inseam might be a little shorter since I wear my pants lower nowadays. My jacket has ballooned to 46R. Have I always been an endomorph in disguise?
