Sometimes it's the little things that help you lose weight, especially if their first name is "Tony". You can do it! Now using the biggest thing of all -- money -- to help you shape up: LoseItorLoseIt.
Just launched by two admittedly overweight programmers in Philly, Lose It helps the insufficiently motivated drop lbs by holding their cash hostage until their weight-loss goals are met, financially-incentivizing people who were otherwise inclined to put their money where their mouth was. The 10-week plan starts after entering your weight loss goal (10, 20, or 30lbs) and throwing some cash in escrow (the minimum's $100, the max is 5K), which is then subtracted as proportional penalties should you miss weigh-in or target loss (1, 2, or 3lbs) on any given week, with no forgiveness for "partial credit", meaning doodling a parabola won't help if you still look like one. For additional motivation in the form of peer pressure, they'll also make your profile public, allowing others to see your weigh-in results/photos, and assure the validity of your weigh-ins by pushing your weekly info to two "accountability friends" -- though if you can't find any takers, you're probably already The Biggest Loser.
And to make sure you don't get de-motivated by altruism, Lose It assures you that absolutely none of any money you lose will go to anything remotely like a charity, and will instead be pocketed by their team, who just like Tony, always believe in themselves.
