After how many hours of continuous fasting will it take for your body to start burning muscle tissue for energy instead of using its fat or glycogen reserves?

Its not hours, human body will start burning muscle for energy when severly malnourished, being ill for a long time without proper care - under extreme conditions. Even a few days without food for a healthy body will not cause it, its the last resort for the human body when all the other sources are gone. It also depends on what state your body is currently in. Its always good to consult these things with a doctor or a certified trainer who will give you answers based on your body type, state which it is in, etc. Only then you can get accurate answers.
