1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn per day when exercise is taken into account. It's calculated by multiplying your Basal Metabolic Rate (BMR) by an activity factor.

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:

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

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level. For accurate results, use a recent BMR measurement or calculation.

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 your daily activities and exercise.

Q2: How accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism and activity levels can affect actual energy expenditure.

Q3: Should I use this for weight loss?
A: Yes, it can help create a calorie deficit, but consult a healthcare professional for personalized advice.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly or your activity level changes.

Q5: Does this account for muscle mass?
A: Only indirectly through your BMR (which should account for your body composition).
