1. What is the Mayo Clinic TDEE Equation?

The Mayo Clinic TDEE (Total Daily Energy Expenditure) equation estimates your daily calorie needs based on the Harris-Benedict formula. It calculates your basal metabolic rate (BMR) and then applies an activity factor to determine total energy expenditure.

2. How Does the Calculator Work?

The calculator uses the Mayo Clinic TDEE equation:

\[ TDEE = (655 + 9.6 \times weight + 1.8 \times height - 4.7 \times age) \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation first calculates your basal metabolic rate (BMR) - the calories your body needs at rest - then multiplies by an activity factor to account for daily physical activity.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether you want to lose, gain, or maintain weight. It provides a scientific basis for determining appropriate calorie intake for your goals.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. Be honest about your activity level for accurate results. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the calories your body needs at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How accurate is this calculation?
A: The Mayo Clinic formula provides a good estimate for most people, but individual variations in metabolism may affect accuracy. It's best used as a starting point.

Q3: Should I use this for weight loss?
A: Yes, subtract 500 calories from your TDEE for a safe weight loss of about 0.5kg per week. For weight gain, add 500 calories.

Q4: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks if your weight changes significantly, or if your activity level changes substantially.

Q5: Are there limitations to this equation?
A: This equation may be less accurate for very muscular individuals, elderly populations, or those with certain medical conditions affecting metabolism.
