1. What is the Weight Loss Calorie Formula?

The weight loss calorie formula calculates the daily calorie intake needed for sustainable weight loss (about 1 pound per week) by subtracting 500 calories from your maintenance calories.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The formula accounts for your base metabolic needs plus activity level, then creates a 500-calorie deficit for gradual weight loss.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is crucial for sustainable weight loss without extreme restriction that could harm metabolism.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For best results, recalculate as your weight changes.

5. Frequently Asked Questions (FAQ)

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

Q2: What if I want to lose weight faster?
A: It's generally not recommended to create deficits larger than 500-750 calories/day without medical supervision.

Q3: Should I eat back exercise calories?
A: The activity factor already accounts for exercise, so you don't need to eat additional calories for workouts.

Q4: What if my calculated calories seem too low?
A: Women should generally not consume fewer than 1200 calories/day without medical supervision.

Q5: How often should I recalculate?
A: Recalculate every 5-10 pounds lost, as your BMR decreases with weight loss.
