Frequently Asked Questions
What is TDEE?▾
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn per day, including BMR (basal metabolic rate), physical activity, and the thermic effect of food.
How accurate is a TDEE calculator?▾
TDEE calculators provide estimates within 10-15% accuracy. They work best as starting points — adjust based on actual results over 2-4 weeks.
How many calories should I eat to lose weight?▾
A safe deficit is 500 calories below your TDEE, which leads to about 1 pound of weight loss per week. Never go below 1,200 (women) or 1,500 (men) calories per day.
