1. What is TDEE?

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including basal metabolic rate and physical activity. It represents the energy your body needs to maintain its current weight.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( Calories \) — Daily calorie intake (kcal/day)
• \( days \) — Number of days
• 3500 — Calories in one pound of body fat

Explanation: This formula calculates expected weight loss based on the calorie deficit created by consuming fewer calories than your TDEE over a specific period.

3. Importance of Weight Loss Prediction

Details: Predicting weight loss helps set realistic goals, plan nutrition strategies, and maintain motivation during weight management programs.

4. Using the Calculator

Tips: Enter your TDEE, daily calorie intake, and the number of days. All values must be valid positive numbers for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this weight loss prediction?
A: This provides an estimate based on the 3500-calorie rule. Individual results may vary due to metabolic adaptations and other factors.

Q2: What if my calorie intake is higher than my TDEE?
A: The calculator will show a negative value, indicating expected weight gain rather than weight loss.

Q3: How can I calculate my TDEE?
A: TDEE can be estimated using formulas that consider your BMR (Basal Metabolic Rate) and activity level, or measured through specialized tests.

Q4: Why 3500 calories per pound?
A: This is a widely accepted estimate that one pound of body fat contains approximately 3500 calories of energy.

Q5: Should I use this for long-term weight loss planning?
A: While useful for short-term predictions, metabolic changes over time may require adjustments to your calorie deficit for continued progress.
