I'm in your boat. My mom was always thin, but picky as fuck with poor eating habits. My dad (and his whole family) were deathfats. Because I was never made to try new foods or eat fruits and vegetables, I never grew out of my own picky eating and ate like a typical fat. My dad croaking of a heart attack my senior year was the wake up call I needed to set me straight for adulthood. I started forcing myself to eat the foods I "hated" and drink more water which "had no flavor". The rest of my family is a smattering of humans and fats. No real shitlords/ladies.
