Easy bet.

I wrestled in high school. Wasn't overweight at all at the time. I am 6'3" and at the time my natural weight was 183. I wrestled 155 and was constantly yoyoing my weight which isn't ideal but I liked my sweets and beverages too much and also wasn't getting any counsel on proper nutrition and maintaining weight.

I once lost 13 lbs in a 24 hour span. Basically through dehydration. I worked out is a "sweatbox" for at least 8 of those hours. Spent another couple in a sauna. Had no food or beverage whatsoever. Chewed gum and spit out whatever saliva I managed.

I would hate to think of having to do this now 20 years later but for 10K I'm sure I could. Especially since I now naturally weigh 235. Heck I'd even drop 20 for the 10K.
