TDEE, or Total Daily Energy Expenditure, is the total number of calories your body uses in one day. It’s a combination of all the energy your body requires to keep you alive, move around, digest food, and more.
Here’s what makes up your how to calculate TDEE: Ultimate Guide to Your Daily Calorie Needs:
- Basal Metabolic Rate (BMR): Calories burned just to keep your body functioning at rest (like breathing and circulation).
- Thermic Effect of Food (TEF): Calories burned digesting and absorbing food.
- Non-Exercise Activity Thermogenesis (NEAT): Calories burned during everyday activities like walking, cleaning, or typing.
- Exercise: Calories burned during workouts, sports, or structured activity.
TDEE Formula:
TDEE = BMR + TEF + NEAT + Exercise

🎯 Why Is TDEE Important?
Knowing your TDEE is key for achieving any health or fitness goal. Whether your goal is to lose fat, gain muscle, or maintain your weight, understanding how much energy your body uses every day allows you to make smart dietary choices.
Benefits of Knowing Your TDEE:
- Prevents overeating or undereating
- Helps you set realistic goals
- Improves workout and diet efficiency
- Supports sustainable fat loss or muscle growth
Here’s how TDEE ties into your goals:
- 🔻 Fat Loss: Eat fewer calories than your TDEE (usually 500–750 less)
- 🔺 Muscle Gain: Eat more calories than your TDEE (usually 250–500 more)
- ⚖️ Maintenance: Eat close to your TDEE
🧠 How to Calculate Your TDEE
➤ Step 1: Calculate Your BMR
BMR is the number of calories your body needs at rest. The Mifflin-St. Jeor Equation is one of the most accurate formulas for calculating BMR.
Men:BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + 5
Women:BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) – 161
📝 Example:
A 30-year-old woman, 65 kg, 165 cm tall:BMR = 10×65 + 6.25×165 – 5×30 – 161 = 1396.25 calories/day
➤ Step 2: Choose Your Activity Level
Next, you multiply your BMR by a number that reflects your physical activity level.
| Activity Level | Multiplier |
|---|---|
| Sedentary (no exercise) | 1.2 |
| Light exercise (1–3 days/week) | 1.375 |
| Moderate exercise (3–5 days/week) | 1.55 |
| Very active (6–7 days/week) | 1.725 |
| Super active (twice daily workouts) | 1.9 |
➤ Step 3: Calculate Your TDEE
Determine Your TDEE: Take your BMR and multiply it by the activity multiplier.
📊 Continuing our example:
If our 30-year-old woman is moderately active (multiplier = 1.55):TDEE = 1396.25 × 1.55 = 2164 calories/day
That means she needs 2164 calories per day to maintain her current weight.

⚖️ TDEE vs. BMR – What’s the Difference?
Many people confuse TDEE and BMR, but they’re not the same.
| Metric | What It Measures | Use Case |
|---|---|---|
| BMR | Calories at rest | Basic survival needs |
| TDEE | Total calories burned daily | Full energy requirement |
Key Difference:
- BMR is just one component of TDEE
- The whole picture is TDEE
💪 How to Lose Weight with TDEE
You must establish a calorie deficit, or consume fewer calories than you burn off, in order to lose weight.
Weight Loss Formula:
Calories = TDEE – 500 to 750
This typically results in losing about 0.5–1 kg per week, which is a sustainable pace.
Advice for Successful Fat Loss:
- To keep muscles, use resistance exercise.
- Eat enough protein (2g/kg of body weight)
- Every 4-6 weeks, evaluate progress and make adjustments.

🏋️♂️ Using TDEE to Build Muscle
To build muscle, you need to eat in a calorie surplus, ideally:
Calories = TDEE + 250 to 500
This surplus gives your body the energy to build new muscle tissue.
Muscle Gain Strategy:
- Eat high-protein meals regularly
- Focus on progressive overload in training
- Increase calories if weight gain stalls
Avoid going too high with your surplus—it leads to fat gain, not just muscle.
🥗 Macronutrients and TDEE
TDEE tells you how many calories you need, but to make real progress, you must also balance your macronutrients:
- Protein: Repairs and builds muscles
- Carbs: Primary energy source
- Fats: Hormone regulation and brain health
Sample Macro Split (2000 calories):
- Carbs (40%) = 800 calories = 200g
- Protein (30%) = 600 calories = 150g
- Fats (30%) = 600 calories = 67g
🔁 Adjust these ratios based on goals:
- Low-carb for fat loss
- High-carb for endurance training

🔁 When Should You Recalculate TDEE?
TDEE isn’t a fixed number. You should recalculate it when:
- You lose or gain 5+ kg
- Your exercise routine changes
- You shift goals (from fat loss to bulking, etc.)
- Every 4 to 8 weeks during any diet or fitness phase
🔬 Factors That Influence TDEE
Your TDEE isn’t just about your workout frequency. Several factors influence it:
- Age – Metabolism slows down as you age
- Gender – Men generally have higher TDEE
- Muscle Mass – More muscle = more calories burned
- Activity Level – More movement = higher TDEE
- Genetics – Some people naturally burn more
- Hormones – Thyroid, insulin, and cortisol all play a role
🚺 TDEE Differences Between Men and Women
While the formula for TDEE is the same, there are gender-specific differences:
Women often have:
- Lower BMR (less lean mass)
- Fluctuating metabolism (menstrual cycle, menopause)
- Unique needs during pregnancy or breastfeeding
That’s why women may need to recalculate their TDEE more often.
📲 Fitness Apps That Track TDEE

🧨 TDEE Myths Busted
Let’s clear up some common misconceptions.
❌ False: “You should always eat less than your TDEE.”
Wrong! Only if you want to lose fat. For muscle gain or maintenance, you need more.
❌ “TDEE doesn’t change.”
Not true. It shifts with weight, age, and activity.
❌ “Just exercise to boost TDEE.”
Not quite. Building muscle and increasing NEAT (daily movement) are often more effective.
❓ How to calculate TDEE | FAQs
Q: Can I use TDEE with intermittent fasting or keto?
✅ Yes! TDEE works for any diet. Just adjust your eating window or macros accordingly.
Q: Is TDEE 100% accurate?
🔍 It’s an estimate. Monitor your weight every week and adjust intake as needed.
Q: Should I eat back calories burned during workouts?
🤔 If your TDEE already factors in exercise, no need—unless your workouts suddenly become more intense or longer.
