Weight Loss Competition Formula

[RhysGM]

Does anyone have or can think of a good formula to run a fair weight loss competition? My ideas so far and their issues;

Starting fat - current fat = total fat lost

Unfair to those who only want to loose a small amount of fat.


( Starting fat - current fat ) / starting weight = % of fat lost of initial body weight

Problem is the heaviest will always be at the top and the lightest always at the bottom. Those with the most to loose will generally loose more per week.


( Starting fat - current fat ) / starting fat = % of initial fat lost

Gives a fairer calculation however, severely overweight people will always be at the bottom, due to only be able to loose a maximum amount of weight.

The problem with that is what method do you intend to use to accurately measure body fat % at the start and end calipers have a lot of variance and the best methods will have cost associated with them that people may not be up for paying? For weight loss I've always just done percentage of weight loss as that way a pound is all relative to how heavy you were at the start since it's easier to lose at 300 lbs versus 200 lbs etc. So a pounds of weight lost should be worth more when you are 200 lbs versus 300 lbs.
