The contest

So I agreed to compete with my friend for one month to lose weight. The idea is we will weigh in at ww every week. Each week the person with the highest percentage of weight loss wins for the week. The loser has to pay $15 into the pot. The person with the highest over all at the end of the 4 weeks wins the pot.
It's a good idea in theory but man I'm going to be broke. I tried really hard this week. Foregoing a lot of things I would have eaten but to no avail I weighed myself at home and there has been no change. I am so frustrated.
While working out last night i was thinking about how fat people even when they lose the weight will always have to work out harder than the average person just to keep it off. I really don't like working out now why do I think I will be any more willing to work out when I've lost the weight.
