1. What Is a Maintenance Calories Calculator?

Definition: This calculator estimates your Total Daily Energy Expenditure (TDEE) based on your Basal Metabolic Rate (BMR) and activity level.

Purpose: It helps you determine how many calories you need to maintain your current weight based on your activity level.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{TDEE} \) — Total Daily Energy Expenditure (kcal/day)
• \( \text{BMR} \) — Basal Metabolic Rate (kcal/day)
• \( \text{Activity Factor} \) — Multiplier based on activity level (1.2-1.9)

Explanation: Your BMR represents calories burned at complete rest, which is then multiplied by an activity factor to account for daily movement and exercise.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether your goal is maintenance, weight loss, or muscle gain.

4. Using the Calculator

Tips: Enter your BMR (use our BMR Calculator if unknown) and select your activity level. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my BMR?
A: Use our BMR Calculator or the Mifflin-St Jeor equation based on your age, gender, weight, and height.

Q2: What activity level should I choose?
A: Be honest about your exercise habits. Most people overestimate their activity level.

Q3: Why does TDEE matter for weight loss?
A: To lose weight, you need to consume fewer calories than your TDEE (typically 300-500 kcal less per day).

Q4: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes.

Q5: Is TDEE the same for everyone with the same weight?
A: No, TDEE varies based on body composition, age, gender, and other individual factors.
