The brain and nervous system only get fuel from glycogen. Glycogen comes from carbohydrates. If you are on a workout routine, muscle recovery requires glycogen as well! Fat cannot be turned into glycogen, but protein can. That means that protein will be stripped from the muscle and used for energy if you don’t provide it through carbohydrates. Yes, your boby will actually break down its own muscle tissue! Never cut carbs out completely, and be very carful scaling them back. The average person needs 50-60% from there daily calories, which on a 1500cal diet comes out to 187.5-225g a day.
