Lose 10 pounds challenge in Jan

The only problem I have with this challenge is it's inaccuracy and the possibility of someone getting bummed out from what they think are lack of results. The challenge should be Body transformation, not weight loss.
Please let me explain why.
Lets say you want to loose 25 lbs. So you start cutting back on your calories. You then decide to take up some sort of exercise program. Lets say Cardio with some weight training. This way you tighten your muscles while loosing body fat which will net much quicker results.
Heres where the problem comes into play. ( I am also using my own personal experience here ).
Even though you are loosing Body Fat because of Calorie cutting, you are actually weighing more on the scale for the next few weeks. This is because you are weight training. Muscles are heavier than fat. So, You will loose the Challenge by the weight gain or no change in weight you are seeing, yet you will look better in the mirror and your clothes will start to fit better.

So I would recomend the Challenge to be a "Body Transformation" Challenge. This way the winner would be the person who transformed there body in that period of time.
The other problem with this type of Challenge is that the more overweight you are, the quicker the pounds come off in the beginning. So if someone has 80 pounds to drop, and someone else has 20, The person weighing more will loose much more in the same time period. Which may get a little frustrating to the person with less weight to loose because although they may be working just as hard, they are not seeing the same results.

I dont want to come off as nit picking. I just want to see everyone succeed in there goals and clarify and, or suggest along the way. I hope no one minds
Good luck to all!
