Your total daily calorie burn.
TDEE is every calorie you burn in a day. Enter your details and activity to get the maintenance number that anchors any calorie goal.
TDEE is your BMR multiplied by an activity factor. To lose weight, eat below this number; to gain, eat above it. See the weight-loss calculator to turn it into a target.
BMR times how much you move.
Your total daily energy expenditure is your resting burn scaled up for activity. We estimate the resting part, your BMR, from your age, sex, height, and weight with the Mifflin-St Jeor equation, then multiply by an activity factor.
The activity multiplier is the part people get wrong most often. Desk-bound with occasional workouts is closer to light than moderate. When in doubt, pick the lower band, because overestimating activity is the classic reason a calorie plan stalls.
Once you know your TDEE, a goal is simple: eat below it to lose, above it to gain. Turn it into a specific target with the calorie or weight-loss calculators, then log your meals in the free calorietrack.ai web app.

- 03Burning 1,000 calories a day for weight lossBurning 1,000 calories a day through exercise can help create a deficit, but it takes a large amount of activity and you cannot reliably out-train your diet. Combining a modest calorie reduction with regular movement is usually more effective and sustainable than relying on exercise alone.
- 04Cutting 1,000 calories a day for weight lossCutting 1,000 calories a day from your maintenance level is a large deficit that points toward roughly 2 pounds of loss a week using the rough 3,500-calorie-per-pound rule. It can work for some people, but it is aggressive, hard to sustain, and worth discussing with a healthcare provider first.
