1. What is Weight Loss Calorie 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 time frame you specify.

2. How Does the Calculator Work?

The calculator uses the weight loss calorie formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( loss \) — Desired weight loss (kg)
• \( date \) — Target date
• \( start \) — Start date
• 7700 — Calories per kg of body fat

Explanation: The formula calculates the daily calorie deficit needed to lose the specified weight over the given time period.

3. Importance of Calorie Deficit

Details: To lose weight, you need to consume fewer calories than you burn. This calculator helps determine exactly how many calories you should eat daily to reach your goal by your target date.

4. Using the Calculator

Tips: Enter your TDEE (use a TDEE calculator if unknown), desired weight loss in kg, start date, and target date. All values must be valid (TDEE > 0, loss > 0, target date after start date).

5. Frequently Asked Questions (FAQ)

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

Q2: Why 7700 calories per kg?
A: Research shows that 1 kg of body fat contains approximately 7700 kcal of energy.

Q3: Is this calculation accurate for everyone?
A: While the formula provides a good estimate, individual results may vary due to metabolic differences and body composition.

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