The favorites you enter are specific to your current Weight Loss Plan. For example, if you add favorites for the BITES Smart plan, they will not be available for the BITES Flex plan. This is because the each plan uses different nutrition information and calculations to produce a food score. You will have to re-enter your favorites items if you switch your weight loss plan. That being said, your prior favorites will show if you ever decide to switch back to your old plan.
