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 activity. It's crucial for weight management and nutrition 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 based on activity level (1.2-1.9)

Explanation: The equation accounts for your base metabolic needs multiplied by your activity level to estimate total daily calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight loss (eat below TDEE), maintenance (eat at TDEE), or weight gain (eat above TDEE). It's fundamental for personalized nutrition planning.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For best results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate, but individual variations exist. Track your actual weight changes to fine-tune.

Q2: Should I use this for weight loss?
A: Yes, subtract 300-500 calories from your TDEE for moderate weight loss (0.5-1 lb/week).

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

Q4: What if I'm between activity levels?
A: Choose the lower level if unsure - it's better to underestimate than overestimate activity.

Q5: Does this account for exercise calories?
A: Yes, through the activity factor. For precise tracking, you may need to log exercise separately.
