I haven’t eaten any crisps since new year and I’m starting to feel like the habit and craving is passing! This is huge news as my evening crisp habit was NOT good - hope everyone is having a great weekend!

Weighed in this morning and am down from the beginning of the week. Just what I needed to help me stay on track through the weekend. I usually gain back anything lost during the week on the weekends I needed this motivation.

Last chance to invite friends to join the game! Growing the pot adds to the fun for everyone. The player who gets the most friends to join each day becomes the game's Most Valuable Player, and we'll award an overall MVP once invitations can no longer be sent.

The weekends are always my downfall with trying to stay with a healthy eating plan. This weekend I will be stronger than the urge to eat treats and unhealthy snacks!!
