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 burned at rest)
• \( \text{Activity Factor} \) — 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 — Extremely active (very hard exercise & physical job)

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management. Consuming more than your TDEE leads to weight gain, while consuming less leads to weight loss.

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 accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism can affect actual TDEE.

Q2: Should I eat my exact TDEE to maintain weight?
A: Yes, but monitor your weight over time as TDEE can change with body composition and activity levels.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight, activity level, or body composition changes significantly.

Q4: What if I'm between activity levels?
A: Choose the lower level if unsure, as people often overestimate their activity.

Q5: Does TDEE include calories burned from digestion?
A: Yes, the thermic effect of food is already accounted for in your BMR.
