What is BMR (Basal Metabolic Rate)?
BMR stands for Basal Metabolic Rate. It represents the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions, such as breathing, circulation, and cell production. Even if you stayed in bed all day, you would burn these calories.
What is TDEE (Total Daily Energy Expenditure)?
TDEE stands for Total Daily Energy Expenditure. It is the total number of calories you burn in a day, including exercise and physical activity. To maintain weight, your calorie intake should match your TDEE. To lose weight, you need to eat below your TDEE (Calorie Deficit).
