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

Hey guys, I’m Chance! I’ve been doing brightlineeating off and on for 8 years. My goal with this 6 months is to make it my lifestyle permanently. I’m kicking things off with a brightlineeating 14 day challenge. The challenge is just writing down exactly what I’m going to eat the night before and eating exactly and only that the next day. I want to continue to do brightlineeating 90% of the year for the rest of my life because I know how good I feel when I’m taking care of my body in this way.

So I will continue to work on planning my daily meals and plan to make them brightlineeating compliant 90% of the time. The other 10 % will be planned holidays or vacation if I want to.

I’m also going to get back into my daily habits that support my health. Such as consistent moderate exercise meditation and journaling. I’m posting on here for social support and to support all of you in your goals as well.

Hi Chance! I love how you're focusing on consistency and making this a lifestyle change instead of expecting perfection. Wishing you the best!! You got this.
