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 your 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 you determine how many calories you should consume to maintain, lose, or gain weight. It's fundamental for creating effective diet and fitness plans.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How is TDEE different from BMR?
A: BMR is the calories you burn 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 TDEE.

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

Q4: How do I use TDEE for weight loss?
A: Consume 300-500 calories below your TDEE for gradual weight loss (about 0.5-1 lb per week).

Q5: Can TDEE change day to day?
A: Yes, it varies based on your daily activities. The calculator gives an average estimate.
