If you are a very active instructor, you would likely need considerably more than 1400 calories. Your net calories-or energy availability-is the amount of energy in calories you actually provide your body after exercise expenditure is deducted from caloric intake. So, if you ate 2100 calories and burned 700 in total exercise, then you leave your body with 1400 calories to fuel your Resting Metabolic Rate, Thermic Effect of Food, and Non-exercise activity. These four make up your Total Daily Energy Expenditure-what you need in a day to maintain weight and body composition according to activity.
