The Biggest Loser... Family Style

I have come up with the idea of my family competing in our own Biggest Loser competition. We are going to have a contest to see who can lose 20 pounds first.

I need y'all's help with determining what the prize should be. Keep in mind that we're not talking about prizes like a trip, or a car, or anything that extravagant. Just a good incentive for us to go ahead and shed those extra pounds.

The contestants so far are me, my mom, my aunt and her husband. I am waiting to hear back from a couple others. Now, I do realize that men and women lose weight at a different pace so maybe we should do like they do on The Biggest Loser and do percentage of weight lost. So say someone's weight is 147 then if that person wanted to lose 20 lbs. then the percentage lost would be 8.6%. Does that sound right? Correct me if I am wrong.

I may even post some before and after pictures. Not in sports bras and bike shorts though. Maybe the after pic will be in a bikini... :-) Yeah right!
