For the most part, you'll be fine just listening to your body. Eat when hungry, stop when full. Especially when you first start, your body is going to take some time to get adjusted to your new plan. My first month, I had some ravenous days and some days where I didn't want to eat a thing. In the end, it balanced for the most part.
During my second month, I started to notice some problems. My energy levels were low, I was moody, and I couldn't get through workouts. So, I tracked my calories out of curiosity and discovered I had been eating 1,000 calories or less for 2 week straight. So, I knew I needed to add some more in.
For your first month, I strongly advise that you don't worry about it. Just listen to your body's signals and everything should work out fine. If you feel good, just go with it!
