Frequently Asked Questions

What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to maintain basic functions like breathing and circulation. It accounts for about 60–75% of total calorie expenditure.

What is TDEE?

TDEE (Total Daily Energy Expenditure) is total calories burned per day including physical activity. It is calculated by multiplying BMR by an activity multiplier. To lose weight, eat below TDEE; to gain, eat above it.

How many calories should I eat to lose 1 kg per week?

1 kg of body fat ≈ 7,700 calories. To lose 0.5 kg/week, create a 500-calorie daily deficit (eat 500 less than TDEE). For 1 kg/week, deficit of 1,000 calories/day — but consult a doctor before aggressive deficits.
