1. What is the Calorie Goal Equation?

The calorie goal equation is based on the Mifflin-St Jeor formula for calculating Basal Metabolic Rate (BMR) in men, adjusted for activity level and then reduced by 500 calories to create a deficit for weight loss.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation first calculates your basal metabolic rate (BMR), then adjusts for your activity level, and finally subtracts 500 calories to create a daily deficit for weight loss.

3. Importance of Calorie Goal Calculation

Details: Calculating an appropriate calorie goal is essential for safe and effective weight loss. A 500-calorie daily deficit typically results in about 1 pound (0.45 kg) of weight loss per week.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. Be honest about your activity level for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates about 1 pound (0.45 kg) of weight loss per week, which is considered safe and sustainable.

Q2: Should I eat fewer calories for faster weight loss?
A: Not recommended. Very low calorie diets can lead to muscle loss, nutrient deficiencies, and metabolic slowdown.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Monitor your progress and adjust as needed.

Q4: When should I recalculate my calorie needs?
A: Recalculate every 5-10 kg of weight loss or if your activity level changes significantly.

Q5: What if I'm not losing weight at this calorie level?
A: You may need to adjust your calorie intake or activity level, or consult with a healthcare professional.
