Free calorie deficit calculator
To provide reliable estimates, the calculator uses multiple scientifically recognized methods for determining Basal Metabolic Rate (BMR)—the amount of energy your body burns while at rest to support essential functions such as breathing, circulation, and cellular activity.
Different formulas approach this calculation in different ways:
-
Mifflin-St Jeor Equation is widely regarded as one of the most accurate methods for estimating BMR in healthy adults and is commonly used by nutrition and fitness professionals.
-
Revised Harris-Benedict Equation is an updated version of a classic metabolic formula and remains a popular reference for calorie estimation.
-
Katch-McArdle Formula incorporates body fat percentage, allowing for a more personalized estimate based on lean body mass. This method may be particularly useful for individuals who know their body fat percentage and have above-average muscle mass.
The calculator compares these proven methods to estimate your calorie needs as accurately as possible. However, all results should be considered approximations, as factors such as genetics, hormone levels, body composition, health conditions, and lifestyle habits can influence actual calorie requirements.
calorie deficit diet is a way of eating where you consume fewer calories than your body burns each day. When your body is in a calorie deficit, it uses stored fat for energy, which leads to weight loss over time. This is the foundation of almost all successful fat loss plans, whether you follow a low-carb, keto, high-protein, or balanced diet approach.
