I’m planning on doing a 21 day fast, cos I’ve done short ones before.
Do you just eat like normal leading up to the fast, or should you start lessening the food and types of foods, and how many days ahead?
It’s easier if you are off sugars for a few days as well as caffeine. And avoid heavy meals during the last couple of days. All that is just to help you avoid headaches and digestive issues as you transition into no food and ketosis.
