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 - to maintain weight, eat at TDEE; to lose weight, eat below TDEE; to gain weight, eat above TDEE.

4. Using the Calculator

Tips:

1. First calculate your BMR using our BMR Calculator
2. Select your activity level honestly
3. The result shows your estimated maintenance calories

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate are the activity factors?
A: They're estimates. For more precision, consider using a fitness tracker.

Q3: Should I recalculate my TDEE often?
A: Yes, especially if your weight or activity level changes significantly.

Q4: Why UK-specific?
A: This calculator uses metric measurements (kcal) commonly used in the UK.

Q5: How should I use my TDEE for weight loss?
A: For steady weight loss, eat 300-500 kcal below your TDEE daily.
