Question 1

What is the difference between BMR and TDEE?

Accepted Answer

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest, while TDEE (Total Daily Energy Expenditure) includes BMR plus all calories burned through daily activities and exercise. Your TDEE is always higher than your BMR and represents your actual daily calorie needs.

Question 2

How accurate is this calculator?

Accepted Answer

This calculator uses established formulas based on extensive research and provides reliable estimates for most people. However, individual metabolism varies due to genetics, muscle mass, and hormones, so results should be used as a starting point and adjusted based on real-world results over time.

Question 3

How can I use my TDEE to lose or gain weight?

Accepted Answer

To lose weight, consume 300-500 calories below your TDEE; to gain weight, consume 300-500 calories above it. A moderate deficit or surplus promotes steady, sustainable changes while preserving muscle mass and overall health.

Question 4

What activity level should I select?

Accepted Answer

Choose based on your typical weekly routine: Sedentary for little to no exercise, Lightly Active for 1-3 days of activity, Moderately Active for 3-5 days, Very Active for 6-7 days, or Extremely Active for daily intense training. Be honest about your habits for the most accurate calculation.

Question 5

Does the calculator work for all body types?

Accepted Answer

Yes, the calculator works for all body types and sizes. However, it estimates based on averages, and factors like muscle mass, metabolism disorders, or medications may affect actual calorie needs. Always consult a healthcare provider for personalized advice.
