No, I am a fat person, but I’m not currently. For 7 years I’ve been at or at less than the weight I was when I was 14.
Why? Because I’ve been fat since I was a kid, and it just kept getting worse with age. I put at least an hour of rigorous gym time into my schedule everyday for the last seven, almost 8 years, and oddly enough, I haven’t been fat since then.
