I have an uncle who married a total cow when I was a kid. He's about 120lbs heavier now and is the exact opposite of my dad (his brother). My dad is 130lbs at 5'6 and used to model for levis and his dad is also a normal human size and swears by fish oil and jogging still in his 80's. It's kind of funny. Any family event we go to, we always try to guess where my aunt's weight has yoyoed (I've seen her from 150lbs to just under 300) and if he got bigger. It's bad, but everyone talked to him about it when he started dating her, and before they got married. I don't even want to mention their kid...
