1. What is the Weight Loss Calorie Formula?

The weight loss calorie formula calculates your daily calorie intake needed to achieve a safe and sustainable weight loss of approximately 0.5-1 kg (1-2 lbs) per week by creating a 500-calorie daily deficit.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

\[ \text{Daily Intake} = \text{BMR} \times \text{Activity} - 500 \]

Where:

\( \text{BMR} \) — Basal Metabolic Rate (calories burned at rest)
\( \text{Activity} \) — Activity level multiplier
\( 500 \) — Calorie deficit for weight loss

Explanation: This formula calculates your maintenance calories (BMR × Activity) and subtracts 500 calories to create a deficit for gradual weight loss.

3. Importance of Calorie Deficit

Details: A 500-calorie daily deficit creates a 3500-calorie weekly deficit, which typically results in losing approximately 0.5 kg (1 lb) of body fat per week. This approach ensures sustainable weight loss while maintaining adequate nutrition.

4. Using the Calculator

Tips: Enter your calculated BMR value and select your appropriate activity level. Ensure your BMR is accurately calculated using a reliable BMR calculator first.

5. Frequently Asked Questions (FAQ)

Q1: Why 500 calories deficit?
A: A 500-calorie daily deficit creates a sustainable weight loss of 0.5-1 kg per week, which is considered safe and maintainable long-term.

Q2: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict, which consider age, gender, height, and weight.

Q3: What if I want to lose weight faster?
A: While larger deficits may lead to faster weight loss, deficits greater than 1000 calories daily are not recommended as they can lead to muscle loss and nutritional deficiencies.

Q4: Should I adjust my intake as I lose weight?
A: Yes, as you lose weight, your BMR decreases. Recalculate your needs every 4-6 weeks or after significant weight loss.

Q5: Is this formula suitable for everyone?
A: Consult with a healthcare professional before starting any weight loss program, especially if you have medical conditions or specific dietary needs.
