Just found this thread, but I had joined a site called
Diet Better. Basically you bet against yourself, and if you lose the weight you win. Unlike biggest loser where the top person takes all, you just have to beat yourself and you are guaranteed at least your money back. A 6 month challenge for 10% of your weight typically is $25/mo, with monthly rounds that accumulate with half going towards the final round. It's been a good motivator for me instead of saying that I can get some more "stuff" as a reward, I get to not lose my money instead, that $2 slice of Costco pizza now has a $125 price tag on top of it.
Now for what I do, to help with motivation aside from the monetary aspect, I use a trend weight system to smooth over those ups and downs that are inevitable. A lot of people quit their diets when they suddenly gain 2lbs in one day after not eating anything for the entire day and hiking Mt. Everest. Check out my current graph in my signature and you'll see the bouncing that my weight does, but you'll also see the smooth blue line that has been going down. Here is my
90 Day graph which shows my climb up. If you join for free then you also have an overview page which shows you your current rate of loss and calorie excess/deficit. The site can be used for both gaining and losing weight.
The disclosure, my friend and I are the two developers of the site. There may be glitches, if you find any let us know. We both work full time jobs and work on this on the side. More updates are coming soon.
Right now I have turned my 7 Day trend and 30 Day trend to going down, but my 90 Day trend is still a slight rise. If I keep up with my exercise and diet plan then I should be able to start pulling that 90 Day trend down! So excited for it.
My Diet Better goals set me at losing 4kg by August 12th, and another 1kg after that by August 19th. Then my 6 month Diet Better goal is a total of 10kg by December 12th, and to maintain that until January 12th.
Unfortunately this 10% diet bet has closed, but there is another one starting on August 12th if anyone cares to try it out. There are also DB4's (4% in one month) that are starting all the time. Wagers may be $25 - $100. 4% is hard, I'm on track, but it's been tough.
