Thin Privilege is not having your metabolism screwed over by your mother putting you on repeated diets from age three because of her own self-loathing and fat-hatred (despite being underweight), and screwing you over for the rest of your life because of diet foods and drinks being almost the only food you knew until leaving home at 17 ( I didn’t taste my first bit of junk food until after I left home, yet I was classified as overweight at age three, and obese from the age of five. Who does that to a kid?). Thin privilege is not being systematically poisoned by your own mother, and having a chance at a healthy life. Thin privilege is not having the realisation that you never really stood a chance.
