Your Total Daily Energy Expenditure or TDEE is how many calories you expend every day. If you want to lose fat, try to eat about 15-20 percent less than you burn.
Although this calculator is a great tool, it’s not perfect. Keep in mind this is just an estimate. Furthermore, many of us overestimate, underestimate, or flat-out lie about how much we weigh or exercise. Even if you were honest with the calculator, it doesn’t mean the number will be 100 percent accurate. Whatever number the TDEE calculator gave to you is a good starting point.
