Potentially a loss of energy, muscle and general fatigue. But if you feel like 1500 is enough to fuel your lifestyle without feeling like crap them I don't think you have much to worry about. Your caloric needs are based on your goals. Is your goal to lose weight, maintain or gain weight and muscle?
@@KillaVision123 I'd say focus only mainly just lifting. Focus on the deadlift, back squatting and some basic bodybuilding upper strength work. Create your deficit through your diet not through cardio. No matter what hit your protein goal. Hitting protein is non negotiable. Be accurate with your food measurements. Accurately hit your calorie goal and nail your protein. I have some vlogs on food measuring and portion control that I think might help. I'll link them in this comment thread for you.
