First day of Keto

Put what you plan on eating for the day tomorrow into the app and see where the macros land. It'll give you an idea what you need to change--generally removing sugars, grains and starches should help.

Googling for "keto breakfast" or lunch, dinner, snacks, foods, recipes... you can come up with tons of ideas what will help meet your numbers. The app also has a meal plan and recipes feature you can try.
