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 your body needs at complete 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 you don't know it) 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 your body needs at complete rest, while TDEE includes all daily activities and exercise.

Q2: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes substantially.

Q3: Can I use TDEE for weight loss?
A: Yes, consuming 300-500 calories less than your TDEE typically leads to weight loss of 0.5-1 lb per week.

Q4: Why are there different activity levels?
A: Different activity levels burn different amounts of calories. The multipliers account for these differences.

Q5: Is TDEE accurate for athletes?
A: While useful, athletes with very high activity levels may need more precise measurements through professional testing.
