1. What is the Weight Loss Calorie Formula?

The weight loss calorie formula calculates your daily calorie needs for sustainable weight loss by combining your Basal Metabolic Rate (BMR) with your Physical Activity Level (PAL) and subtracting a 500-calorie deficit for gradual weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss calorie formula:

Where:

• \( \text{BMR} \) — Basal Metabolic Rate (calories burned at rest)
• \( \text{PAL} \) — Physical Activity Level multiplier
• \( 500 \) — Calorie deficit for weight loss (approx. 0.5kg per week)

Explanation: This formula provides a sustainable approach to weight loss by creating a moderate calorie deficit while accounting for your individual metabolic rate and activity level.

3. Importance of Calorie Calculation for Weight Loss

Details: Accurate calorie calculation is essential for effective weight management. A 500-calorie deficit typically results in losing about 0.5kg per week, which is considered a safe and sustainable rate of weight loss.

4. Using the Calculator

Tips: Enter your BMR in kcal, select your appropriate Physical Activity Level from the dropdown menu. Ensure your BMR is calculated accurately using a reliable BMR calculator first.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how is it calculated?
A: Basal Metabolic Rate is the number of calories your body needs at complete rest. It can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict equations.

Q2: How do I determine my Physical Activity Level?
A: Choose Sedentary for office work with little exercise, Lightly Active for light exercise 1-3 days/week, Moderately Active for moderate exercise 3-5 days/week, Very Active for hard exercise 6-7 days/week, and Extra Active for very hard exercise and physical job.

Q3: Is a 500-calorie deficit appropriate for everyone?
A: While 500 calories is a standard deficit, individual needs may vary. Consult with a healthcare professional for personalized advice, especially if you have medical conditions.

Q4: Should I adjust my calorie intake over time?
A: Yes, as you lose weight, your BMR decreases, so you may need to recalculate your calorie needs periodically for continued progress.

Q5: Are there other factors to consider for weight loss?
A: Yes, macronutrient balance, meal timing, sleep quality, stress management, and overall diet quality are also important factors for successful weight loss.
