1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate (BMR) and all physical activity. It's crucial for weight management and fitness planning.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( activity\_factor \) — Multiplier for daily activity level
• \( exercise\_factor \) — Multiplier for exercise intensity

Explanation: The equation accounts for your base metabolic needs plus additional calories burned through daily activities and exercise.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps determine appropriate calorie intake for weight loss, maintenance, or muscle gain. It's fundamental for creating effective nutrition plans.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown), select your typical activity level and exercise intensity. All values must be valid (BMR > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculation?
A: It provides a good estimate, but individual variations exist. Monitor your weight changes and adjust as needed.

Q2: What's the difference between activity and exercise factors?
A: Activity factor accounts for daily movement (job, chores), while exercise factor accounts for dedicated workout sessions.

Q3: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly (±10 lbs) or your activity level changes substantially.

Q4: Can I use this for weight loss?
A: Yes, subtract 250-500 calories from your TDEE for moderate weight loss (0.5-1 lb/week).

Q5: What if my TDEE seems too high/low?
A: Double-check your inputs. Remember TDEE varies greatly between individuals based on body composition and metabolism.
