1. What is TDEE for Males?

Total Daily Energy Expenditure (TDEE) represents the total number of calories a male burns in a day, accounting for basal metabolic rate (BMR) and physical activity level. It's crucial for weight management, whether aiming to lose, maintain, or gain weight.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for males:

Where:

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

Activity Factors:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise 1-3 days/week): 1.375
• Moderately active (moderate exercise 3-5 days/week): 1.55
• Very active (hard exercise 6-7 days/week): 1.725
• Extra active (very hard exercise & physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps create effective nutrition plans for weight management, athletic performance, and overall health maintenance. It provides a scientific basis for calorie intake decisions.

4. Using the Calculator

Tips: Enter accurate weight in kg, height in cm, age in years, and select the appropriate activity factor that best matches your weekly exercise routine. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use this specific equation for males?
A: The Mifflin-St Jeor equation is considered one of the most accurate for estimating BMR in healthy individuals, and when combined with activity factors, provides reliable TDEE estimates for males.

Q2: How often should I recalculate my TDEE?
A: Recalculate every 4-6 weeks if your weight changes significantly, or whenever your activity level changes substantially.

Q3: What if I'm between activity levels?
A: Choose the level that best represents your average weekly activity. You can also use intermediate values if needed.

Q4: Are there limitations to this calculation?
A: Individual variations in metabolism, body composition, and other factors mean this is an estimate. It may need adjustment based on actual results.

Q5: How should I use my TDEE for weight loss?
A: For weight loss, consume 300-500 calories less than your TDEE daily. For weight gain, consume 300-500 calories more than your TDEE.
