hard to hear people go on about how awful being fat is and not take it personally 
am really very bad for doing this, especially considering one of my children is in the long term process of recovery from anorexia and possibly worse even than that is wearing clothes #3 outgrew some time ago and complaining out loud about being Too Fat To Lead A Normal Life while I'm wearing them
it just seeps out of me without thinking - but of course I got it from my mum, who also has or had sisters who were similar (my cousin died three years ago of pneumonia arising directly from her fucked up eating habits) and of my six siblings two are really weird about food, my long distance running brother is underweight and quite sort of orthorexic, his sport lets him hide his mental abnormality out there in plain sight I think, very anxious about eating correctly and 'healthily', while one of my sisters does a version of that chew and spit thing, which I didn't know was a thing until recently but she's always done it - has a teaspoon of houmous, for example, lets it sit on her tongue for a few seconds then spits it out. She bangs on and on about Being Fat despite having an enviably athletic physique, and runs most days (but not long distance, is more of a gym enthusiast)
it's not an excuse but is hard to override all this when you have always been immersed in it, and everywhere I look generally I see support for restricting calorie intake and exercising more - probably sounds like excuses but these are quite powerful external forces when coupled with this constant constant sense of urgency within
