1. What is Maintenance Calorie?

Maintenance calories represent the number of calories you need to consume daily to maintain your current weight. It's calculated based on your Basal Metabolic Rate (BMR) and activity level.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for BMR and multiplies it by an activity factor:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level (1.2-1.9)

BMR Calculation (Mifflin-St Jeor for Women):
\[ BMR = (10 \times weight\ in\ kg) + (6.25 \times height\ in\ cm) - (5 \times age) - 161 \]

3. Importance of Maintenance Calories

Details: Knowing your maintenance calories helps with weight management - consuming more leads to weight gain, consuming less leads to weight loss.

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 use Mifflin-St Jeor equation?
A: It's currently considered the most accurate BMR equation for healthy individuals.

Q2: How often should I recalculate?
A: Recalculate whenever your weight changes significantly (±5 kg) or your activity level changes.

Q3: What if I'm overweight?
A: The equation works well for most people, but may slightly overestimate for very obese individuals.

Q4: Why different activity factors?
A: More active people burn more calories through daily movement and exercise.

Q5: How accurate is this estimate?
A: It's a good starting point, but individual variations exist. Adjust based on actual results.
