How many calories should I consume a day if I'm trying to cut? I'm 15 years old, 5'11" and 157 lbs. My BMR is about 1844. I workout about 3 times a week, and run HIIT cardio on the off days. I usually consume around 1600 to 1800 calories a day, with mostly protein followed by carbs and good fats. Should I continue to consume this many calories (1600-1800), or a different amount? Thanks.
