Rest means Rest!
Just chiming in to remind everyone what they already know. Rest is more important than eating when building muscle. Yes you can still build muscle on a calorie deficient diet, but, if you are overtrained, you will not only not gain muscle but you could possibly lose muscle. If you need the time, take the time to rest. You will know when you are becoming overtrained.
You loose your fire to go to the gym
You may experience an injury
Your metabolism may even slow down some and
You may loose your appetite
Increase your gains with more recovery and less training.
