I'm not a mom but I can sure tell you my parents would call me out on being a fat bitch(and I was). I didn't grow up to have an eating disorder nor did I think anything out of this world. My parents would simply call me fat until I went down to a healthy weight and to this day I'm thankful for my parents mocking me and calling me names. It taught me it wasn't okay to be fat(and that if I was fat the world and my parents would mock me) and it also taught me the only way to get in shape is if I controlled my eating and if I worked out. My sister also had this happen and she didn't turn to eating disorders or anything. We all turned out to be regular people who regularly work out and eat health. I think its been instilled into peoples minds that if you say something about someones weight it will trigger them to turn to eating disorders which I completely disagree.
