How Many Calories Does the Average Person Burn Per Day?

The number of calories a person burns in a day, also known as their total daily energy expenditure (TDEE), can vary greatly depending on several factors such as age, sex, weight, and physical activity level. However, on average, a sedentary adult burns about 1,800 to 2,000 calories per day.

The average sedentary adult, who engages in little to no physical activity, burns about 1,800 calories per day. This includes activities of daily living such as sleeping, sitting, and light household chores. For women, this number is typically around 1,600 calories, while for men it is around 2,000 calories.

The average sedentary adult burns around 1,800 to 2,000 calories per day. This is the amount of energy expended by someone who engages in minimal physical activity and has a sedentary job. This number can increase or decrease depending on the individual’s activity level.

For example, someone who engages in moderate physical activity, such as brisk walking for 30 minutes a day, can burn an additional 300 to 400 calories per day. Someone who engages in vigorous physical activity, such as running, can burn an additional 500 to 600 calories per day.

Age also plays a role in the number of calories burned per day. As people age, their metabolism slows down, which means they burn fewer calories at rest. For example, a sedentary 30-year-old may burn around 2,000 calories per day, while a sedentary 60-year-old may burn around 1,800 calories per day.

However, this number can increase with physical activity. A person who engages in moderate physical activity, such as brisk walking or cycling, can burn an additional 300 to 400 calories per day. A person who engages in vigorous physical activity, such as running or weightlifting, can burn an additional 600 to 800 calories per day.

Additionally, the number of calories a person burns can also be influenced by their weight. A person who weighs more will burn more calories than a person who weighs less, even if they are engaging in the same activities. This is because the body needs to work harder to move a heavier body.

Other factors that can affect a person’s TDEE include their metabolism, which can vary from person to person, and their age. As a person gets older, their metabolism naturally slows down, causing them to burn fewer calories.

In summary, the average sedentary adult burns about 1,800 to 2,000 calories per day. However, this number can increase with physical activity and weight, and can also be influenced by factors such as metabolism and age. To maintain a healthy weight, it is important to balance the number of calories consumed with the number of calories burned through physical activity.

It’s important to remember that this is just an average, and the actual calorie burn will vary from person to person. If you’re trying to lose weight or maintain your weight, it’s important to consult with a healthcare professional or a registered dietitian to determine your specific calorie needs.

It’s also important to mention that there are other way of calculating TDEE, the Harris-Benedict Equation, the Mifflin-St Jeor equation, and the Katch-McArdle formula are some examples, they all use different variables to estimate TDEE and are a bit more accurate than just taking averages.
