I've actually had this idea for years. When I was a teenager, I was constantly told by classmates or family members, "I wish I was like you and could eat anything I want and stay so skinny!"

I didn't understand the information in my original comment at the time, but it occurred to me it might make a fun documentary to have me live with someone morbidly obese for a month and eat everything they eat when they eat it and see if I gained weight.
