  • When I joined DietBet 3 months ago I had no idea
    sitting here now that I would already be down 30+ lbs.
    Another 35 to go. Can't wait to get there! Can't believe
    that it is so close. Haven't been this weight in 9 years.
  • Officially out of the Obese BMI category
    and into the overweight category.
    I WILL be in the normal range
    by the time this bet is over.
  • DietBet really motivated me. I lost almost 16 lbs
    by drastically changing my habits. For the first time in 10 years,
    I'm under 230 lbs and I'm so close to One-derland!
    Thank you for the motivation. It changed my life.
  • New websites and apps known as weight loss
    wager programs are encouraging dieters to gamble
    their way to a leaner figure, betting on whether
    they can shed unwanted pounds.
  • Four-week games organized by DietBet, have
    been run at more than 500 companies, allotting cash
    prizes to any participant who sheds 4% of body weight.
    90% of players slim down, averaging a 5.4-pound loss.
  • New web services don't just help keep you
    focused on your goals. They pay you to stick to them.
    Result: You feel more committed to your ambitions
    and the odds that you'll achieve them rise.
