1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn per day when exercise is taken into account. It's calculated by multiplying your Basal Metabolic Rate (BMR) by an activity factor.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories your body needs at complete rest)
• \( Activity\ Factor \) — Multiplier based on your activity level (1.2-1.9)

Explanation: The equation accounts for both your body's basic energy needs and additional calories burned through physical activity.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is crucial for weight management. Consuming more than your TDEE leads to weight gain, while consuming less leads to weight loss.

4. Using the Calculator

Tips: Enter your BMR in calories (use a BMR calculator if unknown) and select your activity level. For best results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculator?
A: This provides a good estimate, but individual variations in metabolism and activity can affect actual TDEE.

Q2: Should I eat my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes.

Q4: Why is activity factor important?
A: Physical activity can increase your calorie needs by 20-90% above your BMR, making this the most variable part of the equation.

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 calories from your TDEE for gradual weight loss (0.5-1 lb/week).
