BMR tells you how many calories your body burns at rest. But you don't spend all day lying still. TDEE — Total Daily Energy Expenditure — is the real number: the total calories your body burns in a typical day, including all movement, exercise, and daily activity. It is the single most important number for managing your weight.
TDEE is the total number of calories your body burns in 24 hours, accounting for your activity level. It is made up of four components:
| Component | What it includes | % of TDEE |
|---|---|---|
| BMR (Basal Metabolic Rate) | Calories burned at rest to keep organs functioning | 60–70% |
| TEF (Thermic Effect of Food) | Calories burned digesting food | 8–10% |
| EAT (Exercise Activity) | Planned workouts, gym sessions | 5–15% |
| NEAT (Non-Exercise Activity) | Walking, fidgeting, household chores, standing | 15–30% |
NEAT is the most underestimated component. A person with an active job (teacher, construction worker) can have a TDEE 500–800 calories higher than a desk worker of the same size — just from daily movement, not formal exercise.
Step 1: Calculate your BMR using the Mifflin-St Jeor formula.
Step 2: Multiply by the correct activity multiplier.
Men: BMR = (10 × kg) + (6.25 × cm) − (5 × age) + 5
Women: BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161
| Activity Level | Description | Multiplier |
|---|---|---|
| Sedentary | Desk job, no exercise. Most urban Indian IT professionals. | BMR × 1.2 |
| Lightly Active | Light walking, 1–2 gym sessions per week | BMR × 1.375 |
| Moderately Active | Exercise 3–5 days/week, active commute | BMR × 1.55 |
| Very Active | Hard exercise 6–7 days/week or physical job | BMR × 1.725 |
| Extra Active | Athlete training 2× per day, manual labour | BMR × 1.9 |
28-year-old Indian man: 75 kg, 175 cm, works in IT (sedentary), goes to the gym 3× per week.
BMR = (10 × 75) + (6.25 × 175) − (5 × 28) + 5 = 750 + 1093.75 − 140 + 5 = 1,708 kcal
Activity level: Lightly to Moderately Active → use 1.375 to 1.55
TDEE range: 1,708 × 1.375 to 1,708 × 1.55 = 2,348 – 2,647 kcal/day
| Goal | Daily Calories | Expected Result |
|---|---|---|
| Aggressive fat loss | TDEE − 750 | ~0.75 kg/week fat loss |
| Standard fat loss | TDEE − 500 | ~0.5 kg/week fat loss |
| Gentle fat loss | TDEE − 250 | ~0.25 kg/week fat loss |
| Maintain weight | = TDEE | No change in weight |
| Lean muscle gain | TDEE + 200 | Slow, quality muscle gain |
| Aggressive bulk | TDEE + 500 | Faster gain with some fat |
Never eat below your BMR (typically 1,400–1,800 for most Indian adults). Going below causes muscle loss, hormonal disruption, and metabolic adaptation that makes long-term weight management harder.
The most common reasons:
You can, but many people prefer to eat slightly less on non-training days. A practical approach: eat at TDEE on workout days, and TDEE minus 200–300 on rest days. The weekly average drives results, not any single day.
Every 4–6 weeks, or whenever you lose or gain more than 3–4 kg. TDEE is not static.
No — women generally have lower BMRs due to lower average muscle mass, and therefore lower TDEEs. The activity multipliers are the same, but the starting BMR differs.
