If you've ever wondered how many calories your body burns while doing nothing, you're not alone. Many people are concerned about their caloric intake and output, and want to know exactly how many calories their body burns throughout the day. Fortunately, there is an answer. The number of calories your body burns when doing nothing, also known as your basal metabolic rate (BMR), is the amount of energy your body uses to maintain its normal functions. This includes breathing, circulating blood, and digesting food.
Your BMR is affected by many factors, including your age, body composition, sex, and genetics. Your BMR can also be affected by environmental factors such as altitude, temperature, and stress. Knowing your BMR can help you determine how many calories your body needs to function optimally.
What Is Basal Metabolic Rate?
Basal metabolic rate, or BMR, is the amount of energy your body uses to maintain its normal functions, including breathing, digesting food, and circulating blood. It's measured in kilocalories per hour (kcal/hr). The BMR of an adult is typically between 1,400 and 1,800 kcal/hr, depending on their age, sex, body composition, and genetic factors.
Your BMR can be affected by environmental factors such as altitude, temperature, and stress. For example, a person living at higher altitudes will have a higher BMR than someone living at sea level because the air is thinner at higher altitudes and the body needs to work harder to get oxygen. Similarly, stress can increase your BMR because your body is working harder to maintain its normal functions in the face of stress.
How To Calculate Basal Metabolic Rate?
The most accurate way to calculate your BMR is to use a metabolic testing machine. These machines measure the amount of oxygen your body is consuming and use that data to calculate how many calories your body needs to maintain its normal functions. However, these machines can be expensive and are not widely available.
Alternatively, you can estimate your BMR using one of several equations. These equations take into account your age, sex, height, and weight. However, they are less accurate than a metabolic testing machine and should be used as a rough guide only.
How Many Calories Does Your Body Burn Doing Nothing?
The number of calories your body burns when doing nothing depends on your BMR. As mentioned above, the BMR of an adult is typically between 1,400 and 1,800 kcal/hr. This means that if you do nothing for an hour, your body will burn between 1,400 and 1,800 kcal. This number can vary depending on your age, sex, body composition, and environmental factors.
How To Increase Your Basal Metabolic Rate?
If you want to increase your BMR, you should focus on building muscle mass. Muscle tissue requires more energy to maintain than fat tissue, so having more muscle will increase your BMR. To build muscle, you should incorporate strength training into your workout routine. Additionally, you can increase your BMR by eating regularly and avoiding long periods of fasting.
Conclusion
Knowing how many calories your body burns while doing nothing is important for understanding your caloric needs. Your BMR is affected by many factors, including your age, sex, body composition, and environmental factors. The most accurate way to calculate your BMR is to use a metabolic testing machine, but you can also estimate your BMR using an equation. On average, an adult's BMR is between 1,400 and 1,800 kcal/hr. To increase your BMR, you should focus on building muscle mass and eating regularly.
