Personalized Metabolic Diagnostic
Metabolic Adaptation Risk
With your target of 1,915 kcal, your caloric deficit is optimal (~20.7%). Your metabolic slowdown risk is minimal if you preserve resistance training.
Daily Step & Cardio Target
Aim for 8,500 - 10,000 steps daily to maintain non-exercise activity thermogenesis (NEAT) without burning out recovery pathways.
Optimal Protein Timing
Consume 35-40g of protein every 3-4 hours across 4 meals to maximize muscle protein synthesis and maintain lean muscle tone.
What is Total Daily Energy Expenditure (TDEE)?
Total Daily Energy Expenditure (TDEE) is the comprehensive estimation of the number of calories your body burns in a single 24-hour period. It factors in everything from involuntary cellular maintenance (like breathing, brain operation, and blood circulation) to your rigorous athletic workouts and non-exercise daily movements. Understanding your precise TDEE is the scientific foundation for intentional weight loss, fat reduction, or lean muscular hypertrophy.
1. Basal Metabolic Rate (BMR)
Accounts for approximately 60% to 75% of your total calories. This is the baseline metabolic energy your organs consume if you stayed resting in bed all day.
2. Non-Exercise Activity (NEAT)
Accounts for 15% to 20% of your energy. Encompasses all spontaneous physical activity that is not deliberate exercise—such as walking, typing, standing, and cleaning.
3. Thermic Effect of Food (TEF)
Accounts for roughly 8% to 10% of calories burned. The metabolic cost required to digest, metabolize, and store food nutrients. Protein has the highest TEF (20-30%).
4. Exercise Activity (EAT)
Typically 5% to 15% of your daily burn. Includes structured physical workouts, resistance training, cardio sessions, and competitive athletic sports.

TDEE Calculator: Find Your Total Daily Energy Expenditure Wondering how many calories your body really needs every day? Whether you want to lose fat, build muscle, or simply maintain your weight, the answer starts with one number: your TDEE, or Total Daily Energy Expenditure. In this guide you will learn what TDEE is, how it is calculated, and how to use it to set smart calorie goals.
What Is TDEE (Total Daily Energy Expenditure)?
TDEE is the total number of calories your body burns in a 24-hour period. It includes everything: the energy used to keep you alive at rest, the energy used to digest food, and the energy you spend moving, from walking to the shop to a hard gym session.
If you eat roughly your TDEE each day, your weight will stay about the same. Eat less and you create a calorie deficit, which leads to weight loss. Eat more and you create a surplus, which leads to weight gain.
The 4 Parts of Your Daily Energy Expenditure
Your TDEE is the sum of four components:
- Basal Metabolic Rate (BMR): the energy your body needs at complete rest for breathing, circulation, and cell repair. It is the largest part, usually around 60 to 75 percent of your TDEE.
- Thermic Effect of Food (TEF): the calories burned digesting and absorbing what you eat, roughly 10 percent of your intake. Protein has a higher thermic effect than fats or carbs.
- Exercise Activity: planned workouts such as running, cycling, or weight training.
- NEAT (Non-Exercise Activity Thermogenesis): everyday movement such as walking, cooking, cleaning, fidgeting, and standing.
How to Calculate TDEE: The Formula
The standard method has two steps.
Step 1: Calculate your BMR using the Mifflin-St Jeor equation. It is widely considered one of the most reliable formulas for healthy adults.
- Men: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) + 5
- Women: BMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age) - 161
Step 2: Multiply your BMR by an activity factor.
TDEE = BMR x Activity Factor
Activity Level | Description | Multiplier |
|---|---|---|
Sedentary | Little or no exercise, desk job | 1.2 |
Lightly active | Light exercise 1 to 3 days a week | 1.375 |
Moderately active | Moderate exercise 3 to 5 days a week | 1.55 |
Very active | Hard exercise 6 to 7 days a week | 1.725 |
Extremely active | Very intense training or a physical job | 1.9 |
TDEE Calculation Example
Let's calculate TDEE for a woman who is 45 years old, 165 cm tall, and weighs 60 kg, with a moderately active lifestyle.
- BMR = (10 x 60) + (6.25 x 165) - (5 x 45) - 161 = 1,245 calories per day
- TDEE = 1,245 x 1.55 = about 1,930 calories per day
This means she can eat around 1,930 calories daily to maintain her current weight.
How to Use Your TDEE for Your Goals
To lose weight
Eat below your TDEE. A common approach is a deficit of about 10 to 20 percent, or up to roughly 500 calories a day, which supports steady fat loss while helping you keep muscle. Extreme crash diets are hard to sustain and can slow your progress.
To maintain weight
Eat close to your TDEE and keep your activity level consistent.
To gain muscle
Eat a small surplus, such as 250 to 500 calories above your TDEE, combine it with strength training, and eat enough protein.
How Accurate Is a TDEE Calculator?
A TDEE calculator gives an estimate, not an exact figure. Genetics, body composition, hormones, sleep, stress, and daily movement all vary from person to person, and your TDEE also changes as your weight and activity change.
Treat the result as a starting point. Follow it for two to four weeks, track your body weight trend rather than a single weigh-in, and adjust your calories up or down based on the real results.
Tips to Increase Your TDEE
- Walk more: raising your daily step count is one of the easiest ways to boost NEAT.
- Lift weights: building lean muscle can raise the calories you burn over time.
- Eat enough protein: it has a higher thermic effect and helps preserve muscle.
- Stay consistent with exercise: regular training raises your overall activity level.
- Sleep well: poor sleep can reduce energy and make you move less during the day.
Frequently Asked Questions
What is the difference between BMR and TDEE?
BMR is the energy your body burns at complete rest. TDEE is BMR plus the calories burned through digestion and all physical activity, so it is always higher than BMR.
How many calories should I eat to lose weight?
Subtract a moderate deficit, around 10 to 20 percent, from your TDEE. Avoid going too low, because very low calorie intake is hard to maintain and may cost you muscle.
Which activity level should I choose?
Be honest and choose the lower option if you are unsure. People tend to overestimate how active they are, which can make the result too high.
How often should I recalculate my TDEE?
Recalculate whenever your weight changes by about 3 to 5 kg, or when your workout routine or daily activity changes noticeably.
Is the TDEE calculator suitable for everyone?
It is designed for healthy adults. If you are pregnant, under 18, or have a medical condition, speak with a doctor or registered dietitian before changing your diet.
