TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day. It consists of: BMR (60-75%), the thermic effect of food TEF (10%), NEAT - non-exercise activity thermogenesis (15-30%), and EAT - exercise activity thermogenesis (0-15%).

How do I use TDEE for weight loss?

Create a caloric deficit by eating less than your TDEE. A deficit of 300-500 calories per day leads to about 0.5-1 kg (1-2 lbs) of weight loss per week. Never eat below your BMR as this slows metabolism and causes muscle loss. Combine diet with exercise for best results.

How do I use TDEE for muscle gain?

Create a caloric surplus by eating 300-500 calories above your TDEE. Consume adequate protein (1.6-2.2g per kg of body weight) and follow a structured resistance training program. A moderate surplus minimizes fat gain while maximizing muscle growth.

How to choose the right activity factor?

Activity factor guidelines: 1.2 (sedentary, desk job, little exercise); 1.375 (light exercise 1-3 days/week); 1.55 (moderate exercise 3-5 days/week); 1.725 (heavy exercise 6-7 days/week); 1.9 (very active, physical labor or daily intense training). When in doubt, choose conservatively.

Does TDEE change as I lose weight?

Yes, TDEE decreases as you lose weight because a smaller body requires fewer calories. Recalculate your TDEE every 5 kg (10 lbs) of weight loss. This is why weight loss plateaus occur—your maintenance calories are lower than when you started.

Do I need to count calories every day?

Not forever, but tracking for 1-2 weeks helps you understand portion sizes and food composition. After that, you can estimate intuitively. Weigh yourself weekly and adjust based on trends. Using a TDEE calculator initially sets a scientific foundation for your diet.

❓ About TDEE

Total Daily Energy Expenditure (TDEE) is the total calories your body burns in a day. It's the key metric for science-based weight management.

Four Components of TDEE

BMR (60-75%): Basal metabolic rate, calories for basic life functions
TEF (10%): Thermic effect of food, calories burned digesting food
NEAT (15-30%): Non-exercise activity, daily movements like walking, chores
EAT (0-15%): Exercise activity, intentional physical training

Common Mistakes

❌ Exercise alone is enough for weight loss — diet matters more (80/20 rule)
❌ Eating as little as possible is best — below BMR slows metabolism
❌ Exercise burns unlimited calories — your body adapts over time
✅ Recalculate TDEE periodically as your weight changes
