I'm 6ft 220 and I'm 19. I've had a slow metabolism my whole life but I lift 5 data a Week and do some cardio. Is eating 1500 cals a day way to low and could it be slowing down my weight loss since it might mess with my metabolism? Or is 1500 good? My bmr is 2200. But I'm doing a little more than 500 less to speed up fat loss but could it be faster if I eat 1700?Like would eating 1700 increase my metabolism?
