Being a fat person myself, I've made it a point not to give people shit for the what they do with their bodies. I know how much it sucks when people feel entitled to give me unsolicited advice or talk about their "concerns" with my body, so I try not to do it to them. Sometimes, I slip up, and when I do I apologize.

The way I see it, it's none of my business if someone wants to lose weight or not. There will still be people that try to tell you you're wrong. Keep doing your thing anyway.

Do what's best for you. No one knows your body better than yourself.
