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

So just in case they don't - then I'll be doing intermittent fasting during the day so I don't gain much, if anything...

Went on a bike ride to office today again, 20km headwind all the way, then hopefully tail wind on the way home this afternoon.
Lot's of exercise this weekend, running two times, been hitting about 600 golfballs on the driving range. Have some soar muscles right now :-)

My weigh-in today is somewhat misleading. As I wrote last week I bounced up and down but I refused to accept it so I let my weight 'stand' - the truth is that I by Tuesday last week was at 95 kilos. Which makes my last 6 days as 2.6 kilos lost. But I'm below what I need to be so I'm happy. But I'll be keeping to the plan until we hit official weigh-in. Having put a Laurent-Perrier champagne on cooling - a side bet with my wife :)
