1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including your basal metabolic rate (BMR) and activity level. 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

Activity Factors:

• 1.2 — Sedentary (little or no exercise)
• 1.375 — Lightly active (light exercise 1-3 days/week)
• 1.55 — Moderately active (moderate exercise 3-5 days/week)
• 1.725 — Very active (hard exercise 6-7 days/week)
• 1.9 — Extra active (very hard exercise & physical job)

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps determine your daily calorie needs for weight maintenance, loss, or gain. It's fundamental for creating effective diet and exercise plans.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. The calculator will estimate your total daily calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: It provides a good estimate but individual variations exist. Track your results and adjust as needed.

Q2: Should I use TDEE for weight loss?
A: Yes, consuming 300-500 calories below TDEE typically leads to safe weight loss of 0.5-1 lb per week.

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

Q4: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q5: Can TDEE change day to day?
A: Yes, based on activity levels. The calculator provides an average estimate.
