One-size-fits-all calorie recommendations do not work.
They must be customized to each individual.
To accurately determine your daily calorie amount: Enter your current weight, age, height, and gender into the calculator. Do your best estimate of how much exercise you will be doing.
The results will show how many calories you may eat in order to maintain or lose weight. You don't need to adjust this depending on your exercise rate - that is factored into the equation. The maintenance value is the same as what some people call Total Daily Energy Expenditure (TDEE).
