Q: Mike on non training days is it ok to eat 300 calories less? I want to obtain only muscle if possible and little too no fat. Is it ok?

A: In my experience changing calories between training and non-training days did not produce better results than simply keeping them even throughout. It's much more important to make sure your average calorie level is just right to keep gaining weight but as slowly as possible. So I recommend focusing on that as the main goal and not worrying too much about changing calorie level on non-training days.
