Just wanted to comment on the 'most weight lost' as the end point. That always favors large men because A) they have a lot of weight to lose and B) Can usually drop a ton of weight quickly.

A better measurement is % of total body weight lost, because it evens the playing field a bit more between men and women. It still favors REALLY heavy people over moderately heavy people, but it's still a better indicator than just total weight lost.

Just thought I'd throw my $0.02 into the ring! Couple of people explain it here on Reddit.

I know this, that's why I made it so everyone participating wins, not just the "biggest loser".
