Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.
Check out the FAQ to learn more!

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

  • Does anyone struggle with this?

    Our desire to do things "perfectly" can have such an opposite effect. When we don't live up to those expectations, it can really send us into a tailspin can't it?

    This is your reminder that it's not all or nothing. Real progress will only come when you let go of "perfect" and start thinking of a trajectory that is slowly going in the direction of your goals. You got this!!

    Who can relate to this? Has anyone been successful in changing their mindset?

So true! I try to remind myself that 5 out of 7 days are still way better than nothing but it is still discouraging. Still working on the mindset.

This has been one of my biggest roadblocks to eating healthy and losing weight. Getting better at it though :)

  • Research shows that short bursts of activity can improve overall health and weight loss and ditching the “all or nothing” mentality may help individuals be more consistent with their activity.

    Breaking exercise into small chunks on your overscheduled days can also keep your confidence up, since skipping it altogether can make you feel tired, guilty, or depressed.

    To get us all thinking, here are 5 ways to get a burst of energy in your day.

    1. Jog in place, squat, plank, or wall sit during commercials (or between episodes while streaming).

    2. Dance like nobody is watching! Have a 5-10 minute dance party and see if it doesn’t also elevate your mood!

    3. Spend 5-10 minutes walking or climbing stairs for every hour you spend sitting at your desk.

    4. Do standing pushups (against the wall or counter) while waiting for dinner to cook.

    5. Do a quick sweat-sesh before each shower. Try a few kettlebell swings, burpees, jumping jacks, lunges, etc.

    Is there something you do each day that you can turn into 5-10 extra active minutes? Share some ideas you have!

Love this thank you.
I used to do squats in commercial breaks on tv, but I rarely get tv time anymore

Rowing machine or bouncing on a yoga ball while swinging my arms like I'm running. Great with hand weights too.
Great activity for foot injuries too if you can manage with your leg elevated.

  • A few weeks ago I noticed as my weight was dropping I was losing both fat and muscle. Since 2/15, when I started tracking my biometrics with the Renpho, I had lost 10.8 lbs total, 7.6 lbs of fat, 3.0 lbs of muscle, and 0.2 lbs from bone mass. Perhaps I could maintain my muscle if I eat between 0.5 and 0.8 grams of protein per pound of body weight. While holding my calorie goal the same, I upped my beans, tofu, and nooch. A couple of days later I decided to add in some plant based protein powder. I can see improvements in my ratio of muscle to fat, but It's too soon to tell what the true effect might be. Despite holding my calories below my BMR it looks like I have stopped losing both muscle and fat. Oh yeah that's right I have been on a plateau since 4/24, a coincidence... perhaps. The Excel graph below shows my muscle data in blue and fat data in gray. Both have been reduced by constants so they are easier to compare.

Welp, I caught my son's cold. At least I know it's not covid. First time any of us have been sick in over a year. I'll try my best to stay on track! :/

Does the actual scale need to be the same each weigh in? Yesterday I found that my cat peed all over mine!! I tried wiping it off but then when I turned it I saw drips so I then had to keep spraying it. I put it outside in the sun and hoping maybe it will work again when I put the batteries back in.
If I have to use a different scale to weigh in, then am I disqualified?

No it doesn't. Some people have shared that they've had theirs break and not all scales weigh the same

Time for a new cat, just kidding! I love cats, anyways I have used different scales without an issue
