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

I am pretty far off from my weigh out but have decided that I want to keep trying to get as close as possible.
I just started a new job and it has been pretty stressful so far. Unfortunately I gave into the stress today and binge ate some snacks. I’m just looking for advice on how to better improve my relationship with food and the guilt that I now am feeling after my slip up.

Maybe skip the relationship with food and just break up with it :grimacing:


It is important not to deny yourself anything. Then there's no room for guilt... find healthy alternatives that taste good. And take care you eat enough. Binge eating often happens with me if my deficit was too high for too long or I am lacking Carbs or Proteins. If I feel like having that pizza, I have some and share the rest. And then come back to healthy habits... just never give up! I found noom helpful to learn healthy patterns...

Almost there. I need to be very disciplined for some more days... even though my body is asking for a break...

Only 500g to go :grin:

Thanks. Seeing it zoomed out like that makes it seem a lot more linear than it really was. Hides a lot of bumps and plateaus.

Back to counting my calories again. I hate doing it, but it's my Reset Button whenever I feel like I need some discipline. My mind always fights it as a long-term weight loss strategy though because I know I can't count calories forever! But it gets me back on track every time.

I struggle with this a lot as well!


I feel you.
I always found it difficut to loose, not to maintain. Maybe because I am creating good habits on the way down... but I have way to go... thinking about giving me a break after my next Flex Kickstarter...

All the praise to you right now! I was a teacher for 11 years before being laid off at the end of the year last year. I have since left education. I know I would not be mentally strong enough to teach right now!

  • Holy Sweatballs y’all ????
    I did the CrossFit open 21.3 & 21.4 and it kicked my ass!!!!!! I am happy that I’m losing weight but the strength and muscles I am building are the best part!
    I posted my workout in my stories on IG if you’re interested @radchickrevamp
    I am sooo proud of myself for not giving up!!!!

Yes...food is good but I think it helps to try to remember it’s for fuel not fun. It’s tough but it’s all mental!
