How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

Does this actually work?

Out of 911,304 DietBetters, 99.12% have lost weight during their challenges. Combined, they've lost 17,141,258 lbs and won $62,263,235. In other words...yes.

All results shown on DietBet are from actual users. Individual results may vary.

Don't take our word for it

I've had both a you've not won after I put in to put in my weigh in which is 1kg less than what my goal was because I didn't meet my goal and then a you've won notification 30 min ish ago .
Now I'm assuming I lost too much weight to win the game as its below my goal but I'm totally confused by the 2 different notifications within a very short period of each other.

Boo!! Not close at all on this one. I lost 5 lbs but needed to lose closet to 8. I think these flex kickstarters are starting to be too fast a pace for me. Congrats to everyone that won, and everyone that lost weight!!

  • I was so excited to get this announcement!! I feel like I've been working hard tracking my food and staying on point with my workouts. I know I definitely got stronger during these last few weeks. Now I'm hoping that with the pounds coming off I'll start to see more definition. Great job everyone!!

I have seen my definition come from starting kettlebell swings and planks.

Huge congratulations to all the winners! I didn’t win this one, but I’m strangely feeling so positive this morning because I know my weight is in the right place! I’m going to join the upcoming Member Maintainer challenge — and keep joining maintenance challenges! — because that’s where I’m meant to be! Celebrating many NSVs, but a big one is I notice how much stronger I am and my arms have leaned out. Way to go EVERYONE! Stay healthy!

Ahhh still about 1.5 pounds away! I haven’t seen the scale move at all in weeks because I’ve been so stressed out (defending my dissertation in 4 days!!). Hoping I’ll see it come off later in the week.

Try not to stress to much. You got this: both the game and the dissertation! Congrats Doctor :)


I hope defending your dissertation was successful. You have another 2 days to go to meet your goal weight. I was at 82.3kg only 5 days ago and now surpassed goal weight with 78.2kg this morning through venturing into a water fasting week. Maybe a 24 to 36h fasting will do the trick? That's doable without medical assistance. I am very experienced with fasting but would not recommend doing longer fasts alone for the first time...

Definitely needing the extra time... still in it though! Not giving up.

I am within striking distance. Never give up. Walking in 100 degree heat as the sun is going down may be helpful.

Last week for weigh ins!!! Check-in time!! I still have a stubborn 2ish lbs to go, and I am currently on vacation. Hoping to ride this week out at a steady weight and eat clean on Monday-Tuesday next week to get this goal done!
How is everyone else doing??

Congrats! You both can do it! I'm not going to make it. I gained out of the gate and didn't turn it around until a few days ago. I'm feeling better now. But it's too late for this game.

Deanna F.

Under 2 left for me and my body has sure been stubborn. We can do this!

I am below my goal for that but still want to lose a little more for my personal goals. This last 4 % will be a real challenge for me, and if I don’t meet it I’m okay with that, but I want to push myself to try!!! I’ve gotten SO much out of DietBet and it feels new again starting this new challenge! Best of luck to all!
