Reddit mentions of Keto Answers: Simplifying Everything You Need to Know about the World's Most Confusing Diet

So let's be clear what ketosis is. (Keeping it simple) Ketosis is when your body has a lack of carbs in the body and it can no longer produce enough glucose from those carbs to be fuel for your body. As a result your body changes and switches to a secondary fuel source but turning fat into keotenes, and essentially burning those. (Simplified explanation). You have plenty of fat on your body to fuel your body for quite sometime. You will not starve. IN FACT, Fasting does the exact same thing! When you fast, your body burns through it's glucose and switches to burning fat to produce keotenes to fuel your body. You literally can food fast for weeks if you want and there are MANY medical benefits to it. NOTE: I said food fast, not water fast. Drink tons of water. Get electrolytes.

Any Doctor who says fasting slows fat burn is a doctor you should stay away from. It's literally moronic advice. You will have ups and downs as your metabolism changes and adjusts, but over all, fasting burns fat. Ketosis burns fat. Caloric deficient burns fat. Fasting is the ultimate caloric deficit. 2 days of fasting a week is nothing.
