Frequently Asked Questions

What is BMR and how is it calculated?

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest. We use the Mifflin-St Jeor equation, which is considered the most accurate for modern populations, accounting for your weight, height, age, and gender.

What are the different activity levels?

Sedentary: Little or no exercise. Lightly active: Light exercise 1-3 days/week. Moderately active: Moderate exercise 3-5 days/week. Very active: Hard exercise 6-7 days/week. Extra active: Very hard exercise, physical job, or training twice per day.

How accurate is this calorie calculator?

This calculator provides accurate estimates based on the Mifflin-St Jeor equation, which has an accuracy rate of about 90%. However, individual metabolism can vary based on genetics, muscle mass, and other factors. For precise calorie needs, consider consulting a registered dietitian.

Why are there different calorie goals?

Different goals require different calorie intakes. To lose weight safely (about 0.5 kg per week), you need a 500-calorie deficit. To gain weight (about 0.5 kg per week), you need a 500-calorie surplus. Maintenance calories keep your current weight stable.

Can I use this calculator for weight loss or weight gain?

Yes! This calculator provides specific calorie targets for both weight loss and weight gain. For weight loss, aim for the calorie deficit shown. For weight gain, aim for the calorie surplus. Always consult a healthcare provider before making significant changes to your diet.
