Frequently Asked Questions – Calorie Calculator

1. What is a calorie calculator used for?
A calorie calculator helps you estimate how many calories your body needs every day to maintain, lose, or gain weight. It’s a useful tool for meal planning, fitness tracking, and achieving your weight goals.

2. How does this calorie calculator work?
This calculator uses the Mifflin-St Jeor equation, one of the most accurate formulas to estimate your Basal Metabolic Rate (BMR). It then multiplies that by your activity level to estimate your total daily calorie needs.

3. How many calories should I eat to lose weight?
To lose weight safely, reduce about 400–500 calories per day from your maintenance level. This helps you lose around 0.5 kg (1 pound) per week — a healthy and sustainable rate.

4. How accurate is this calorie calculator?
It provides a close estimate for most people, but actual calorie needs vary depending on metabolism, muscle mass, and daily routine. Use it as a guide, not an exact prescription.

5. What is the best way to track my calories?
You can track your calories using apps like MyFitnessPal, Lose It!, or any food journal. Logging your meals helps you stay accountable and understand your eating habits better.

6. How many calories should I eat to gain muscle?
If your goal is to build muscle, increase your calorie intake by about 300–500 calories per day above your maintenance level and combine it with regular strength training.

7. Does exercise affect calorie requirements?
Yes! The more physically active you are, the more calories your body burns. That’s why it’s important to select the correct activity level in the calculator to get the most accurate result.
