Daily Calorie Needs Calculator
Daily Calorie Needs
Calculate Total Daily Energy Expenditure (TDEE). This represents the total number of calories you burn per day, including physical activity, based on the Mifflin-St Jeor formula.
Patient Metrics
Clinical Precision & Methodology
The Total Daily Energy Expenditure (TDEE) calculator integrates your Basal Metabolic Rate (BMR) with the Katch-McArdle activity multipliers. It provides exact caloric targets to maintain, lose, or gain weight based on thermodynamics.
Thermodynamic Accuracy
Utilizes the standard 3,500 kcal rule per pound of fat to generate reliable targets: a 500 kcal/day deficit yields approximately 0.5kg (1lb) of weight loss per week.
Activity Multipliers
Standard clinical multipliers (1.2 to 1.9) capture Non-Exercise Activity Thermogenesis (NEAT) and Exercise Activity Thermogenesis (EAT) to determine true energy burn.
Thermal Receipt Export
Generates a high-resolution, perfectly scaled PNG image designed specifically for 80mm thermal printers, enabling instant clinical handouts.
Activity Multipliers (TDEE = BMR × Activity)
