I hate weight. I use to weigh 197 up until Sophmore year of High School.
One day I got on the scale, looked at my weight, and go "Uh.. I'm fat." So I dropped 60 pounds in 5 months.
Obviously I did it an unhealthy way, by not eating and exercising like a mad man, but it worked!
Although, once I got my license, I gained 30 pounds. ~ ~
My biggest fear is getting fat, I NEVER want to look like that again, and I know exactly how it feels to be overweight.
I'm starting to shed it now, though, just in time for Kumoricon!
