I mean, when fatties cry juhn-etiks, it's not that you're fat because your moms fat. You're fat because your mom is fat and made some shitty decisions that obese people tend to make.  Ex: she didn't initiate breastfeeding, when literature shows that not breastfeeding has detrimental consequences including an increased risk of obesity.   She almost certainly did other things that fat moms tend to do, like putting rice cereal in a bottle, and over feeding you as a baby.   She likely fed you insane portions of high calorie high sugar high fat foods.  So no, you aren't fat because it runs in your family. You're fat because fatties gonna fat, and they're going to put you at a disadvantage because of some bad fucking choices.
