This is where you need to decide if your goal is to gain or lose weight. As we all know to gain weight you need to be in a caloric surplus and to lose weight you need to be in a deficit. I’m not going to tell you exactly how many calories to add/subtract to gain or lose because it will be different for everyone. What I will say is that in both cases start small and go from there. Take your estimated maintenance calorie intake and adjust that number a little bit and see how you look, feel, and perform, and go from there.
