Frequently Asked Questions

How many calories should I eat to lose weight?

A deficit of 500 calories per day typically produces about 1 pound of weight loss per week (since 3,500 calories approximately equals 1 pound of fat). Start with a modest deficit of 15–20% below your TDEE and adjust based on actual results over 2–3 weeks.

What is the difference between calories and TDEE?

A calorie is a unit of energy. TDEE (Total Daily Energy Expenditure) is the total calories your body burns per day from all sources: metabolism at rest, digestion, and physical activity. Your daily calorie goal is set relative to your TDEE — below it to lose weight, at it to maintain, above it to gain.

What is TDEE?

TDEE stands for Total Daily Energy Expenditure — the total number of calories your body burns in a day. It includes your Basal Metabolic Rate (the energy used at rest), the thermic effect of food (digestion), and all physical activity including structured exercise and daily movement.

How is TDEE different from BMR?

BMR (Basal Metabolic Rate) is the calories burned at complete rest — just to keep organs functioning. TDEE multiplies BMR by an activity factor to account for everything you do during the day. BMR is always lower than TDEE; for a lightly active person, TDEE is typically 1.4–1.5x their BMR.
