How the Calculation Works (Simple Explanation)
Your body burns calories every day.
This is called your metabolism.
The calculator first finds your Basal Metabolic Rate (BMR).
BMR means the calories your body needs to stay alive.
Then it adjusts the number based on your activity level.
If you move more, you burn more calories.
To lose weight, you must eat fewer calories than you burn.
A safe weight loss is about 0.5 to 1 kg per week.
Simple Example
Let’s say:
- Your body needs 2,200 calories per day
- You eat 1,700 calories per day
That creates a 500-calorie deficit daily.
Over one week, that equals about 3,500 calories.
That is roughly 0.5 kg of weight loss.
This method is supported by trusted health sources like the
National Institutes of Health (NIH)
