How Calorie Needs Are Calculated
Your daily calorie needs are determined by calculating your Basal Metabolic Rate (BMR) and multiplying it by your activity level. The BMR represents the number of calories your body needs to maintain basic life functions while at rest. We use the Mifflin-St Jeor equation, which is considered one of the most accurate methods for calculating BMR.
Frequently Asked Questions
How accurate is this calculator?
This calculator uses the Mifflin-St Jeor equation, which studies have shown to be highly accurate for most adults. However, it provides an estimate. Individual variations in metabolism, muscle mass, and exact daily activity can slightly alter your true calorie needs.
How to lose weight using calories?
To lose weight, you need to be in a caloric deficit. This means consuming fewer calories than your body burns. A standard, healthy deficit is 500 calories below your maintenance level, which typically results in about 0.5 kg (1 lb) of weight loss per week.
