1. What is TDEE-Based Weight Loss Calculation?

This calculator determines your daily calorie intake needed to reach a specific weight loss goal by a target date, based on your Total Daily Energy Expenditure (TDEE) and the energy deficit required to lose the specified amount of weight.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( weight\_loss\_kg \) — Desired weight loss (kg)
• \( days \) — Timeframe for weight loss (days)
• \( 7700 \) — Calories in 1 kg of body fat (kcal/kg)

Explanation: The formula calculates the daily calorie deficit needed to lose the specified weight over the given timeframe, then subtracts this from your TDEE to give your daily calorie target.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation helps create a sustainable weight loss plan that meets your goals without being too aggressive or ineffective.

4. Using the Calculator

Tips: Enter your TDEE (use a TDEE calculator if unknown), your weight loss goal in kg, and the number of days you want to achieve this goal. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is TDEE?
A: Total Daily Energy Expenditure is the total number of calories you burn in a day, including basal metabolic rate and activity.

Q2: Why 7700 kcal per kg?
A: This is the approximate energy contained in 1 kg of body fat, though individual results may vary slightly.

Q3: Is this calculation accurate for everyone?
A: While the calculation provides a good estimate, individual metabolism and body composition can affect actual results.

Q4: What's a safe rate of weight loss?
A: Generally 0.5-1 kg per week is considered safe and sustainable for most people.

Q5: Should I adjust my calories as I lose weight?
A: Yes, as you lose weight your TDEE decreases, so you may need to recalculate periodically.
