Calories needed per day

According to the FDA, the average adult male in the USA burns about 2,200 to 2,400 calories per day and females about 2,000 to 2,200 calories per day. Your food reserve should reflect this daily average if you want to maintain your current health. The number of calories that you should eat depends of your weight, age, height, and your activity levels.
