Muscle tissue is energy-expensive, so your body will readily demolish some in order to save energy.
This process starts about four hours after you last ate something. So if you feel hungry, your body is already getting rid of muscle tissue !

It highly depend your diet... If you starve yourself you will start to lose within 2 days but if you eat insanely it might be very long... I guess 2-4 weeks while eating at maintenance. It also depend of stuff like genetics and testosterone.
