What players are saying
Big thanks for the motivation to help me to my first weight milestone, i've been struggling to get below 180lbs for a few months now and this game gave me a good push to get here. I look forward to joining another game and hitting another weight milestone with you.
From Jenn’s game community
I cherish the games and what you have created. It's like family. Thank you so much.
From Jenn’s game community
Thank you for hosting. I really love the weekly challenges. They help stay focused when we get distracted by silly things like jobs.
From Jenn’s game community
I’m extremely grateful for your kindness, words of encouragement, and support . The world needs more people like you!
From Jenn’s game community
Thank you for hosting such well-organized DietBet games and including the challenges! You always do such a fantastic job hosting.
From Jenn’s game community
It's only the second game I've won, and I really like the way you structure your games and keep the players motivated.
From Jenn’s game community
I have done several different dietbets over the years (a lot of yours) and I must say yours keep me the most motivated so thank you!
From Jenn’s game community
I am not for sure if I will end up winning as it is getting harder since I am so close to my goal weight but love the accountability and support.
From Jenn’s game community
Your games help me develop good habits.
From Jenn’s game community
The water, nutrition and exercise goals you encourage us with have really begun to change how I live, and I really appreciate it.
From Jenn’s game community
Thank you for helping me focus on positive habits I can add instead of "beloved" things I have to give up.
From Jenn’s game community
It is hard for me to fit self care into my life, which is one of the reasons it's been hard to lose weight; these challenges help me prioritize my health.
From Jenn’s game community
I think I have happily eaten more veggies in the last two weeks than I ever have and I am feeling great! Also I love these weekly challenges - it makes healthy choices easier!
From Jenn’s game community
I love the games, it is such a warm enthusiastic community.
From Jenn’s game community
Thank you for adding in the weekly challenges; while I didn’t complete each one the way I’d hoped to I think even just working towards them made such a difference!
