1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including 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 (1.2-1.9)

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 — Extremely Active (very hard exercise & physical job)

3. Importance of TDEE Calculation

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

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) 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 calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q2: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly (±10 lbs) or your activity level changes substantially.

Q3: Can I use this for weight loss?
A: Yes, consuming 500 kcal less than your TDEE daily typically leads to ~1 lb weight loss per week.

Q4: Why might my actual TDEE differ?
A: Individual variations in metabolism, NEAT (non-exercise activity thermogenesis), and inaccurate activity estimates can affect results.

Q5: Should athletes use different calculations?
A: Extremely active individuals may need more precise methods like calorie tracking with adjustments based on results.
