The Total Daily Energy Expenditure or TDEE is the total amount of calories burned daily and it depends on your lifestyle. Your daily activities also require energy expenditure (walking, sleeping, taking a shower, thinking, eating, cooking, etc.). The Basal Metabolic Rate is just a part of the energy your body consumes.

The lower figure is your Rest Metabolic Rate or RMR - BMR, the higher figure is your current total energy requirement based on your level of activity. Values in Kilocalories abbreviated Cal., also called Calories (both with capital "C"). Extra active: vigorous exercise 2 or more times per day or training for a marathon, triathlon, etc.īasal Metabolic Rate here Total Energy requirements here Notes on our BMR Calculator.Very active: hard strenuous exercise every day, or exercising twice a day.Moderately active: moderate exercise or sports 6-7 days weekly.Lightly active: light exercise or sports 1-3 days a week.Sedentary: little or no exercise, desk job.You can also calculate your TotalTotal Daily Energy Expenditure or TDEE based on your average daily energy output, and this is defined by your lifestyle and level of physical activity: To use our RMR calculator you only need to know your height, your weight, your age, and your gender. Remember that the BMR calculator is just an estimation and that other methods can be used to calculate it.įor instance, one that measures how much oxygen you breathe in and the carbon dioxide that you exhale, and based on these values, it calculates the actual energy burned by your body over a given period. BMR (women) = 655 + (9.6 x wt in kg) + (1.8 x ht in cm) - (4.7 x age in years).BMR (men) = 66 + (13.7 x wt in kg) + (5 x ht in cm) - (6.8 x age in years).In case you are curious, this is the formula (wt is weight, and ht is height.) It has its margin of error (which we discuss further down), but it will give you a good estimation of your RMR. We use the formula that is known as the Harris-Benedict Equation, and which dates back to 1919. We will use both terms "RMR" and "BMR" interchangeably because the scientific papers do the same. With our calculator, you can find out which is your Basal Metabolic Rate or BMR, also known as Resting Metabolic Rate or RMR. Our BMR Calculator How does the calculator work? This is the basic equation governing metabolism:Īnd it is useful to know if you want to lose weight. These nutrients are then reacted with oxygen inside our cells to generate energy and the surplus energy is stored mainly as fat or glycogen (a type of sugar), or as protein (Fat-Free Mass) in our muscles. The body intakes fats, carbohydrates, and protein from food and breaks them down into their building blocks, different types of fatty chains, sugars, and amino acids. These bodily chemical reactions require energy, which our body obtains from the food we eat. Metabolism is an ongoing process, that only stops with death. Metabolism is a series of chemical reactions that keep our body alive, they take place within our body's cells. ![]() ![]() They regulate metabolism by generating energy in a process known as respiration. There are small organelles inside each of your body cells, these are called mitochondria. We are "warm-blooded" animals, meaning that our body keeps a constant temperature (this is also known as homeothermy from the Greek words " homo" = "the same" or "equal" and " thermos" = "warm").Ĭonstant body temperature requires a lot of energy, roughly two-thirds of BMR goes into homeothermy.įor instance, a mouse weighing the same as a "cold-blooded" lizard burns 8 to 10 times more energy to maintain its body temperature ( 1). The energy used by your body to keep your body's cells working properly: their structure, their function, their internal biochemical processes, the gradients in calcium and sodium ions, and protein assembly. RMR is the rate at which your body burns energy when it is resting (its only activities under these circumstances are breathing, blood circulation, and brain activity). What exactly does RMR (or Basal Metabolic Rate - BMR) mean anyway? What is the Resting Metabolic Rate or RMR? Definition of Resting Metabolic Rate ![]() Humans could benefit from fasting and exercising too. Alternate fasting extends lifespan and promotes longevity in nematodes and mice.
