1. What is the Weight Loss Calories Formula?

The formula calculates daily calorie needs for weight loss by first determining maintenance calories (BMR × activity factor) then subtracting 500 calories to create a deficit for approximately 1 pound of fat loss per week.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( activity\_factor \) — Multiplier based on activity level
• 500 — Calorie deficit for ~1 lb/week weight loss

Explanation: The equation accounts for your body's basic energy needs plus activity, then creates a moderate deficit for sustainable weight loss.

3. Importance of Caloric Deficit

Details: A 500-calorie daily deficit typically results in 1 pound of fat loss per week. This moderate approach helps preserve muscle mass while losing fat.

4. Using the Calculator

Tips: Enter your calculated BMR (from a BMR calculator) and select your activity level. For accurate results, use a recent BMR measurement.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 500 calories specifically?
A: 500 calories/day equals 3500 calories/week, which approximates the energy in 1 pound of body fat.

Q2: Is this calculator only for women?
A: While designed for women, men can use the same formula (though BMR calculations differ by gender).

Q3: What if I want to lose weight faster?
A: We don't recommend deficits larger than 500-750 calories/day without medical supervision to avoid muscle loss.

Q4: How often should I recalculate my needs?
A: Recalculate every 10-15 pounds lost, as your BMR decreases with weight loss.

Q5: Should I eat back exercise calories?
A: The activity factor already accounts for exercise - don't eat back calories unless you're very active.
