I used to be very fat. The thing is, there are reasons to be wary. Fat isn't healthy. You can be as body-positive as can be, but you are limited in physical activities, sex, and have myriad health problems. Besides, it's a fact that many people out there aren't so open minded. I personally look to other things than beauty in people. But being fat has drawbacks that all of the positivity and self-appreciation cannot overcome.

For the record, I HATED being fat and always believed I could do better.
