1. What Is Tdee Calculator?

The TDEE (Total Daily Energy Expenditure) calculator estimates your daily calorie needs based on your Basal Metabolic Rate (BMR) and activity level. It represents the total number of calories you burn each day, including both resting metabolism and physical activity.

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 is essential for weight management - whether your goal is weight loss, maintenance, or muscle gain. It provides a baseline for determining appropriate calorie intake.

4. Using the Calculator

Tips: Enter your BMR in kcal/day (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: 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 is this calculator?
A: It provides a good estimate, but individual variations in metabolism and activity can affect actual energy expenditure.

Q3: Should I adjust my TDEE over time?
A: Yes, as your weight, body composition, or activity level changes, you should recalculate.

Q4: How does TDEE relate to weight loss?
A: Consuming fewer calories than your TDEE leads to weight loss, while consuming more leads to weight gain.

Q5: Can TDEE vary day to day?
A: Yes, especially if your activity levels vary significantly from day to day.
