1. What Are Calorie Needs?

Calorie needs represent the number of calories your body requires each day to maintain your current weight, based on your basal metabolic rate (BMR) and activity level.

2. How Does the Calculator Work?

The calculator uses the calorie needs equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\_factor \) — Multiplier based on activity level

Activity Factors:

• 1.2 — Sedentary (little or no exercise)
• 1.375 — Lightly active (light exercise 1-3 days/week)
• 1.55 — Moderately active (moderate exercise 3-5 days/week)
• 1.725 — Very active (hard exercise 6-7 days/week)
• 1.9 — Extra active (very hard exercise & physical job)

3. Importance of Calorie Calculation

Details: Knowing your calorie needs helps with weight management, whether your goal is to lose, maintain, or gain weight. It provides a scientific basis for meal planning.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown) and select your activity level. For accurate results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from calorie needs?
A: BMR is the calories your body needs at complete rest. Calorie needs include your activity level.

Q2: Should I eat exactly my calculated calorie needs?
A: This is a starting point. Adjust based on your goals (deficit for weight loss, surplus for gain).

Q3: How often should I recalculate my calorie needs?
A: Recalculate when your weight changes significantly or your activity level changes.

Q4: Are there limitations to this calculation?
A: Individual variations in metabolism aren't accounted for. Use as an estimate and adjust based on results.

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 calories from your maintenance needs for gradual weight loss (0.5-1 lb/week).
