Building on our basic understanding of Total Daily Energy Expenditure (TDEE), let’s take a closer look at the pivotal components behind the scenes – the Basal Metabolic Rate (BMR) and the activity multiplier.
The BMR represents the minimum amount of energy required to keep your body functioning while at rest. It’s the amount of energy your body needs just to stay alive, even without moving a muscle. It’s influenced by various factors including age, sex, weight, height, and body composition. A higher muscle mass, for instance, results in a higher BMR due to the increased energy requirement of muscles.
But humans are not sedentary creatures. We move around, perform tasks, engage in exercise, and even fidget. This is where the second piece of the TDEE puzzle comes in – the activity multiplier.
The activity multiplier is a number that represents your physical activity level, which gets multiplied with your BMR to calculate TDEE. This number varies based on your lifestyle – a sedentary individual will have a lower multiplier (around 1.2), while an extremely active person might have a higher one (around 2.5).
It’s vital to note that the activity multiplier doesn’t just account for deliberate exercise like a workout session at the gym or a run in the park. It also takes into consideration daily activities such as cleaning, walking, and even standing. This offers a more comprehensive measure of daily caloric expenditure, making the TDEE a more accurate estimate of your body’s energy needs.
In our upcoming blog post, we’ll explore how you can effectively use your TDEE to make smarter decisions about your nutrition and physical activity, supporting a healthier lifestyle.
