What is a metabolic calculator? A metabolic calculator uses your age, height, weight, and activity level to determine your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). By analyzing these metabolic markers, the FitScanned AI generates precise protein, carb, and fat targets to help you lose weight, build muscle, or optimize performance with scientific accuracy.

Your Basal Metabolic Rate (BMR) represents the minimum number of calories your body requires to perform life-sustaining functions at rest, such as breathing, circulation, and cell production.
Total Daily Energy Expenditure (TDEE) is the total amount of energy you burn in a 24-hour period. It combines your BMR with your activity level and the thermic effect of food.
Calculators are great for planning, but real results come from execution. Use the FitScanned app to track your actual intake with AI photo scanning.
