📚 Reference Tables
Activity Level Multiplier Exercise Frequency Typical Profile
Sedentary×1.2Little/noneDesk job, mostly seated
Lightly Active×1.3751–3 days/weekLight walks, casual activity
Moderately Active×1.553–5 days/weekRegular gym sessions
Very Active×1.7256–7 days/weekDaily training or sports
Extra Active×1.92x/day or physical jobAthlete + physical labor
⚠ Common Mistake: Most people overestimate their activity level. Choose based on planned exercise only, not daily movement. NEAT (non-exercise activity) is accounted for within the multiplier range.

🧪 About the Formula: This calculator uses the Mifflin–St Jeor equation (1990), validated as the most accurate BMR predictor for most adults. If you know your body fat %, the Katch–McArdle formula is used instead for greater precision.
Category Men (% Body Fat) Women (% Body Fat) Notes
Essential Fat2–5%10–13%Minimum for organ function

📌 Katch–McArdle Note: When body fat % is provided, we calculate Lean Body Mass (LBM) and use the Katch–McArdle formula: BMR = 370 + (21.6 × LBM in kg). This is more accurate for muscular or very lean individuals.

💧 Calorie Density: Protein = 4 kcal/g • Carbohydrates = 4 kcal/g • Fat = 9 kcal/g. Use these to convert your gram targets to calories and verify your total intake aligns with your TDEE goal.
⏰ When to Recalculate: Recalculate your TDEE every 4–6 weeks, especially if your weight changes by more than 5 lbs, you change your training frequency, or you plateau for 2+ weeks. TDEE is dynamic, not a fixed number.
⚖ For Accuracy: Weigh yourself first thing in the morning, after using the bathroom, and before eating or drinking. Take the average of 3–5 morning weigh-ins to reduce daily fluctuation noise.

TDEE is Total Daily Energy Spending. It shows the whole amount of calories that the body spends during one day. Here includes everything, from physical activity and walking to basic processes like breathing and sleep.

Precise count of TDEE is hard to reach and it adjusts from one day to the next.

TDEE: How Many Calories You Burn Each Day

Three main parts affect TDEE. First comes the basic metabolic rate, or BMR, that points the energy that the body needs to simply exist at rest. Second is the level of activity.

Third the heat impact of food processing. Basic metabolism usually covers 60 to 75 percent of TDEE. Because fat does not use lot of energy to maintain itself, the mass wihtout fat better predicts how many calories the body burns at rest.

For estimating TDEE, start by calculating BMR. Then adjust that value according to the level of activity. Common multipliers apply to various levels of motion.

For sitting it is BMR times 1.2. For a bit active, BMR times 1.375. For medium active.

BMR times 1.55. For a lot active… BMR times 1.725.

For extremely active. BMR times 1.9.

TDEE points the amount of calories that you must receive daily too preserve the current weight. If you eat more than that amount, you gain weight. If less, you lose weight.

To add muscle, start with around 500 calories above TDEE, then expand as needed. To lose around one pound each week, create a deficit of 500 calories under TDEE daily.

Online calculators for TDEE use age, weight, height, gender and activity level to estimate the needed calories to preserve weight. Even so they depend on the user well estimating his activity, and the results are not always precise. They base on statistical averages, so the number can differ.

The wisest way is to consider the result of any calculator only as a rough starting point.

A more reliable way is to carefully follow the eating of foods, weigh yourself daily in the morning as first thing and use the averages of several weeks to estimate the real maintenance calories. Actual data beats every formula. TDEE adjusts according to lifestyle.

Regular daily updates give more steady values, while changes in routine updateeverything.

Bigger muscular mass can raise TDEE, so each person that lifts weights should commonly check his daily intake. Calories from exercise belong to TDEE and need thought during planning of meals. Adding muscle through both cardio and strength training can raise TDEE, because more muscular mass burns more calories through the day.
