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

The game has begun! Lose 6% by your final weigh-in, and you'll be a winner.

Remember that you can weigh in unofficially as often as you like before then - it'll help you stay accountable. (And don't be distracted if anyone appears to have super fast weight loss. There's no bonus points for losing weight the fastest, and only official, Referee-approved weigh-ins determine who wins.)

Good luck and have fun!

Well I’ve tried submitting again, hopefully third time lucky. Apart from it being totm, I cannot explain why the tech has played up today. Fingers crossed. And finally it’s been approved. Yay, now comes the easy bit!!

Oh for goodness sake, I don’t know what is wrong with me today, can’t get anything right. Resubmitted my scale pic and now the full length has disappeared! Do not know what is going wrong.

Totally mucked up, because of the glare on my scales I was going in closer and closer to get number to show and didn’t realise I chopped off word! What an idiot. Waiting now for it to be rejected so I can resubmit.

As it’s the first weighin I’m going to use different scales, don’t know why it was glaring, never done it before, the day has started well!!
