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

Do you include fruits in your diet? No - why? Yes - which ones, how much, how frequently?

Betty K.

Yes. Berries, apples, oranges, grapefruit. 2 servings a day. A serving of berries is 1/2 cup. A serving of grapefruit is 1/2 grapefruit. I get lots of fiber from my fruits.

Always! This time of year it’s mostly berries, nectarines, watermelon and apples. Occasionally I’ll buy some green grapes. :watermelon: :strawberry: :grapes: :peach: :green_apple:

  • Look at that swim yesterday! 2 miles! For some reason my watch lost a 25.... probably during cooldown because I do backstroke and breaststroke and it isn't as reliable at counting those.

    Felt good to get back in the pool after several weeks of not making it a priority....

* Weigh yourself once a week, after waking up and after using the restroom. The body naturally fluctuates in weight from one day to the next so a once weekly weight is the most accurate average.
* Track your calories. No matter your dietary lifestyle calories still matter.
* Drink water! The body will hold onto water if you're dehydrated, giving the false impression of weight gain.
* Keep measurements! Where the numbers on the scale may not reflect could be instead happening in your measurements.
