Quick Answer: The clearest way to learn TDEE is through examples. Using BMR (Mifflin-St Jeor) × activity factor: a sedentary 30-year-old man (75 kg, 175 cm) has a TDEE of about 2,038 kcal; a moderately active 28-year-old woman (58 kg, 160 cm) about 1,759 kcal; and a very active 22-year-old man (68 kg, 178 cm) about 2,960 kcal. These worked examples show how age, size, sex and activity shape your daily calorie needs.
Key takeaways:
- Examples make TDEE easy to understand.
- Activity level is the biggest swing factor.
- Men generally have higher TDEE than women of similar size.
- All figures are estimates to refine with real results.
- Use metric units (kg, cm) as Indians do.
Formulas can feel abstract, so the fastest way to understand TDEE is to see it worked out for real people. In this beginner-friendly guide we calculate TDEE for several Indians of different ages, sizes and activity levels, showing every step. By the end you will be able to picture where your own number might land and understand what pushes it up or down.
Each example uses the same two-step method: first BMR from the Mifflin-St Jeor equation, then TDEE = BMR × activity factor. Remember that these are estimates; your real calorie burn is fine-tuned by tracking your weight over time.
Key takeaway: Watch how much the activity factor changes the final number. The same person can have a TDEE hundreds of calories apart depending only on how active they are.
Example 1 — A Sedentary Office Worker (Man)
Rahul, 30, weighs 75 kg at 175 cm and has a desk job with little exercise. BMR = 10 × 75 + 6.25 × 175 − 5 × 30 + 5 = 750 + 1093.75 − 150 + 5 = 1,698.75 kcal. TDEE = 1,698.75 × 1.2 = about 2,038 kcal per day. To lose fat he might target around 1,600–1,700 kcal.
Example 2 — A Moderately Active Woman
Sneha, 28, weighs 58 kg at 160 cm and exercises three to five days a week. BMR = 10 × 58 + 6.25 × 160 − 5 × 28 − 161 = 580 + 1000 − 140 − 161 = 1,279 kcal. TDEE = 1,279 × 1.55 = about 1,982 kcal per day. Notice her TDEE is close to Rahul’s despite her smaller size, because she is much more active.
Example 3 — A Very Active Young Man
Arjun, 22, weighs 68 kg at 178 cm and trains hard six to seven days a week. BMR = 10 × 68 + 6.25 × 178 − 5 × 22 + 5 = 680 + 1112.5 − 110 + 5 = 1,687.5 kcal. TDEE = 1,687.5 × 1.725 = about 2,911 kcal per day. His high activity gives him a much larger calorie budget.
| Person | Age/Sex | Weight/Height | Activity | TDEE |
|---|---|---|---|---|
| Rahul | 30 M | 75 kg / 175 cm | Sedentary | ~2,038 |
| Sneha | 28 F | 58 kg / 160 cm | Moderate | ~1,982 |
| Arjun | 22 M | 68 kg / 178 cm | Very active | ~2,911 |
| Lakshmi | 45 F | 65 kg / 155 cm | Light | ~1,780 |
Example 4 — A Middle-Aged Woman
Lakshmi, 45, weighs 65 kg at 155 cm and is lightly active. BMR = 10 × 65 + 6.25 × 155 − 5 × 45 − 161 = 650 + 968.75 − 225 − 161 = 1,232.75 kcal. TDEE = 1,232.75 × 1.375 = about 1,695 kcal per day. Age lowers her BMR compared with a younger woman of the same size, a normal effect of metabolism slowing with age.
Example 5 — Using TDEE to Set a Goal
Suppose Sneha (TDEE about 1,982) wants to lose roughly half a kilogram a week. Since about 7,700 kcal roughly equals one kilogram of fat, a daily deficit of around 500 kcal targets that pace. She would aim for about 1,480 kcal a day, keeping protein high with dal, curd, paneer and eggs so she loses fat rather than muscle.
What the Examples Teach Us
Three lessons stand out. First, activity level can matter as much as body size, as Sneha and Rahul show. Second, men typically have a higher TDEE than women of similar weight because of the formula’s constants and body composition differences. Third, TDEE declines with age, which is why calorie needs fall over the decades. These patterns hold across almost everyone.
Benefits of Learning Through Examples
Worked examples build intuition far faster than a bare formula. Seeing numbers for people like you makes it obvious how each input matters and helps you estimate your own TDEE before you even open a calculator. It also makes goal-setting concrete: once you see how a 500 kcal deficit maps to a target, planning your own diet feels achievable rather than mysterious.
Challenges and Limitations
Clean examples can look more precise than reality. Real metabolism varies with muscle mass, genetics, sleep and hormones, so two people with identical stats can differ. The activity factor is a broad estimate, and everyday movement fluctuates. Treat each example as an illustration of the method, and always confirm your own number against how your weight actually changes over a few weeks.
Common Mistakes to Avoid
- Copying someone else’s TDEE. Your number is personal; use your own age, size and activity.
- Overstating activity. Picking a high factor, as the examples show, can add hundreds of calories you may not burn.
- Forgetting age. Older adults have lower BMR, so do not use a young person’s figure.
- Assuming smooth results. Weight loss is rarely perfectly linear week to week.
- Neglecting protein. Hitting calories without enough protein risks losing muscle in a deficit.
- Never recalculating. As weight changes, so does TDEE; update your figure.
Best Practices and Expert Recommendations
- Rework an example with your numbers. Swap in your age, weight, height and activity to personalise it.
- Choose activity honestly. When unsure, use the lower factor and adjust up.
- Set a moderate deficit or surplus. Around 300–500 kcal is sustainable for most goals.
- Track and adjust. Use two to three weeks of weight data to confirm your target.
- Keep protein high. Indian staples like dal, curd, paneer and eggs make this easy.
- Recalculate regularly. Update your TDEE whenever your weight or routine shifts.
Expert insight: If the examples teach one thing, it is that there is no single right calorie number for everyone. Your TDEE is yours alone, shaped by your age, size and how much you truly move.
Example 6 — A Full Day of Eating at TDEE
To make the numbers tangible, let us turn Sneha’s maintenance TDEE of about 1,982 kcal into a realistic Indian day of food. Breakfast might be two idlis with sambar and a small bowl of curd, around 350 kcal. Lunch could be two chapatis, a katori of dal, a katori of vegetable sabzi and a small portion of rice, roughly 550 kcal. An evening snack of a fruit and a handful of roasted chana adds about 200 kcal. Dinner of two chapatis, paneer or egg curry and salad comes to around 550 kcal, and a glass of milk before bed adds another 150 kcal. That totals close to 1,800–1,950 kcal, comfortably within her maintenance range while delivering good protein and fibre.
Seeing a full day laid out this way shows why the TDEE number is so practical. Rather than counting every grain, Sneha can build familiar meals around her target and stay on track. If she wanted to lose weight, she could trim the rice at lunch and the bedtime milk to create her deficit, and if she wanted to gain muscle she could add an extra chapati and a second serving of protein. The TDEE figure is the anchor; the Indian plate does the rest.
Applying the Examples to Your Own Life
The best next step is to pick the example closest to you, then swap in your exact age, weight, height and activity level. Write down the resulting maintenance, deficit and surplus figures, choose the one that matches your current goal, and commit to it for three weeks. Weigh yourself a few mornings each week and take the average, because daily weight bounces around with water and food in the gut. If the average is moving the way you intended, your number is right. If not, adjust your intake by 100 to 200 kcal and continue. This simple loop of calculate, apply, observe and adjust is how the examples in this guide translate into real, lasting results.

Conclusion
These worked examples show how TDEE varies from person to person and what drives it: age, sex, body size and, above all, activity level. Rework one with your own figures, choose your activity honestly, set a moderate deficit or surplus for your goal, and let real weight data over a few weeks confirm the number. With a handful of examples under your belt, calculating and using your own TDEE becomes second nature.
FAQs
What is a good TDEE example to start with?
A sedentary 30-year-old man of 75 kg and 175 cm has a TDEE of about 2,038 kcal. Reworking this with your own age, weight, height and activity is the best way to learn.
Why is a woman’s TDEE often lower than a man’s?
The Mifflin-St Jeor formula uses a lower constant for women (−161 versus +5), reflecting differences in average body composition. At the same weight, men usually have a somewhat higher TDEE.
How does activity level change the example results?
Dramatically. The activity factor ranges from 1.2 to 1.9, so a very active person can have a TDEE nearly 60% higher than a sedentary person with identical body stats.
How do I turn a TDEE example into a weight-loss plan?
Subtract about 300–500 kcal from the TDEE for a sustainable deficit. Roughly 7,700 kcal equals one kilogram of fat, so a 500 kcal daily deficit targets about half a kilogram a week.
Are these example figures exact?
No. They are estimates from standard formulas. Individual metabolism varies, so use the examples as a guide and confirm your own number by tracking your weight.
