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

Been feeling pretty discouraged the last week recognizing I likely wouldn't make my goal. I still tried, but weighed in today having lost 2.3% instead of the required 3%.

I originally comforted myself with the knowledge that if I continue on this course, I will at least win rounds 4 and beyond. But I wanted to win them all, so I'm still disappointed.

The hardest part for me in this is how dedicated I have been to my weight loss this month. I have measured all my food and meticulously tracked my calories to ensure I would win. In some ways it's comforting to feel like I've done a good job -- "I guess this is just the fastest I can lose weight" as an excuse to dismiss accountability... it comes with a feeling of helplessness because I dont know what I could have done differently that isn't moving into unhealthy deprivation territory.

So today I got out a spreadsheet to really try to problem solve what went wrong. After some careful analysis and consideration (and some research), I realised I was overestimating the calories I burn doing hot yoga. I just used the default on my fitness pal but scientific research doesn't support those estimates. With that in mind, I actually did lose close to the amount that would be expected given what I've consumed and done... There were also a lot more days i went "just a bit over" that mattered more than I would have thought when combined with this (my calorie goal was actually set to try to lose 4% as a safety net).

I feel SO MUCH better now knowing what happened and how I can improve moving forward - dont be afraid to sit down with a critical eye at your behaviour/method to make a plan to do better if you haven't made your goal, even if you think you're doing everything right. Knowledge is power!

If you did make your goal -- congratulations!

I heartily endorse bothe “Time Restricted Eating” and not calculating exercise calories into my daily calorie total. Gary Taubes has said that “Calories in-Calories out” as the sole key to weight loss is tragically misleading because it assumes a physics-based system (energy in/energy out) versus reality which is we are complex biological systems. There are so many elements to our bodies’ metabolic systems that also change over time that I think you’ve hit on the one key that works, which is tracking your own personal data and then looking back at the data for the unvarnished truth about the story that data is telling. You’re doing great!!!!

What I love the most is that you didn't stop at "I don't know what I could have done differently". This is where most people stop and then end up quitting.
