Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

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

Made my round 3 goal early! I’m going to challenge myself to lose 9% of my initial weight instead of the official 8% so that I have a bit of a cushion when we get into the holiday season.

I didn't make my last weigh in but I've had some awesome milestones just the same. My jeans are getting bigger, I've gone down two notches on my belt. I've been exercising regularly and watching my diet so it's a matter of time before I reach my monthly goals! #determined #notquitting

So I'm currently in recovery from my disordered relationship with food and binge eating. I'm losing weight slowly now, which is good. And I'm happy to be binge free for a few days now. This will probably be my last diet bet. It's great for the weight loss, but slightly hard on my brain to be constantly thinking about weight loss. It doesn't help me recover like I want to. I want to be free of the diet mindset, and I want a natural relationship to food.

I've entered what people say is the most dangerous stage of my Achilles recovery -- the stage wheee the intense pain has decreased and my range of motion has increased, so I might be tempted to do more than I should. The key is going to be to keep the brace on so I remember I'm not ready to do anything fun yet. I have to remind myself I'm in real danger of a complete rupture if I don't take it easy for the next few months.
In good news, Pilates doesn't aggravate things at all. The classes are too short, and I still need a cardio outlet, but it's something.

I’m in the same place with my hamstring partial rupture (tore it sinking into the splits a few weeks ago :grimacing:). It’s so hard to take it easy now that it feels a bit better! Good luck in your recovery!

Tonight marks the first of 8 nights of the Jewish holiday of sukkot. There will be much food and family. Wish me luck keeping the holiday damage to a minimum- so I can recover before the next weigh-in.

Enjoy the holiday - try to focus on family just a little more than food. (Ha - easy for me to say but not to practice! :wink:)
