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

This is the first time I have “Won” a DietBet. I am down 20+ pounds and that is life changing for me!

  • So excited to win this DietBet. Not only lost weight but saw positive body composition changes when I started lifting weights regularly.

Finally went past my goal but my weight is really fluctuating. I need to figure out why and fix that issue 😊

Watch out for salt! That will make you retain water.

It's normal to fluctuate a couple lbs in a day. So many factors influence water retention and loss.

They have Walmart there

A local gym or recreation center might help you out, if they are open.

  • I’ve met goal for a few challenges yesterday - YAY! My next goal is another 3.6 pounds by 2/11. That’s a stiff climb - I wanna meet it or get as close as possible with applied earnest effort. Then I can enjoy a little splurge for Valentine’s Day before I hit it hard again. #babysteps. Best to all as we press into the goal!

  • OK - Crazy wind here in California right now - got my steps and a little jog at the strip mall near my house so I’d be under some cover and not get hit by a tree branch...! Sheesh! I’m sure the cart sanitizer at Trader Joe’s was wondering about me!
