If you are looking for a free online diet challenge website (just like Biggest Loser), look no further than the new TrackDiet.com. The site lets you run your own biggest loser challenges, including setting the start and end date, while also allowing users to join and keep track of their progress.
It also gives you enough privacy that only the percentages are revealed to other users, not your actual weight. You can check up on your status daily, and it will send reminders to challengers that haven’t updated their weights within the time-limit you set.
Unlike some of the other sites that appear “free”, then charge users to join your “free” challenge, TrackDiet.com is completely free – free to start, and free for members to join and participate. The only thing you have to lose is the weight!
