I guess my "fat logic" would be thinking I don't have a chance. I'm 20, and I weigh 250.
My grandpa has had four heart attacks. My dad died of a heart attack five years ago, at 43. My family history is completely full of diabetes and heart disease.
I remember my dad warning me when I was young of how he would wake up in pain most days from his health.
So when I'm faced with what inevitable, its hard to convince myself it's worth it to try and change things, as much as I want to.
