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

And just like that, our Wedding Day Shape Up Challenge has come to an end. A huge congratulations to everyone regardless of whether or not you hit your weight loss goal.You're all winners in our book because you took that first step and bet on yourselves. The winner of our "3 things I learned during the Wedding Day Shape-Up Challenge" contest is Ellen K! Thank you all for sharing your healthy tips. They were insightful, unique and inspiring! Remember, the secret to losing weight and keeping it off is adopting healthy habits, believing in yourself and surrounding yourself with a supportive community. You are always one choice away from making your goals a reality. Congratulations again everyone, keep up the inspiring work!

I thought I had until 11:59 tonight to submit my weigh in?! I actually made my goal and DIDN'T get the free donut at Dunkin today when I took my students. I wish I would've if I would have known I couldn't submit my weigh-in.


You have until 11:59 PST

Wouldn't it be 8pm right now then?

So I got on the scale this morning and I was 3 lbs heavier. Granted it's THAT time of the month. I'm glad I lost enough weight to off set this gain either way. I am still a winner in this challenge 😁👍💪

I thought I had until this morning! Ah! That's okay. I was .5 away from my goal anyway. So very close! I still lost 5.5 pounds, and will continue on my journey. Thanks for all the support, everyone! I wish you all well in the wedding planning/festivities, and your futures!

Hey Knot - would you consider hosting another one of these?? I had a hard time getting started and will not be a winner this time around.

Where is the Knot? I feel like they have not been around the past two weeks.


I agree! I love this diet bet!! Very good motivation plus it's great to talk to other brides and get advice from you all!!

I didn't make it, but I lost 4 pounds and that's 4 more pounds than I was able to lose in previous months! I'll take it, and I hope to see some of you in the Transformer challenge!

So I didn't make it... but I lost 4lbs! That's a win in my book. Double or nothing with a weekly kickstarter!! Congrats to all who made it, lost anything at all, or just plain feel better!
