Your Basal Metabolic Rate (BMR) is the amount of calories you burn throughout the day by only doing the minimum amount of life-sustaining involuntary biological functions: breathing, the heart pumping blood, the energy it takes to digest food, etc. While your Total Daily Energy Expenditure (TDEE) is the TOTAL amount of calories burned in the day and takes into account all physical activity taken place in that day. Both of these measurements have calculations revolved around them, and they can be an amazing tool for knowing how many calories you need in a day in order to hit your goals for weight gain or loss.
