I wrote a free weight tracking web app based on this idea. You track your weight daily. It gives you some simple analytics on your weight over time. It's a small thing, but tracking your weight every day helps it drop over time and keep you accountable to your diet.
I'm 285 days in a row and I've lost right at 40 lbs. It works.
