How to Increase Basal Metabolic Rate: Understanding the Effects of Age and Lifestyle Factors

Understanding Basal Metabolic Rate and Its Age-Related Changes: Tips for Boosting Your Body's Energy Expenditure

Basal metabolic rate (BMR) is the minimum amount of energy required by the body to maintain basic functions such as breathing, circulation, and organ function at rest. BMR is influenced by several factors such as height, weight, sex, and age. As we age, our BMR gradually decreases, which may contribute to weight gain and other health problems. However, there are ways to boost BMR and increase energy expenditure, even as we get older. In this article, we will discuss BMR and its age-related changes, as well as tips for increasing BMR and promoting a healthier metabolism.

1.What is basal metabolic rate?

Basal metabolic rate (BMR) is the amount of energy required by the body to maintain basic functions at rest. This includes breathing, circulation, and organ function, as well as the energy needed to maintain body temperature. BMR is influenced by several factors, including height, weight, sex, and age.

2.Age-related changes in basal metabolic rate

As we age, our BMR decreases. This is because muscle mass tends to decrease with age, and muscle is more metabolically active than fat. In addition, hormonal changes associated with aging may also contribute to a decrease in BMR. This age-related decrease in BMR may contribute to weight gain and other health problems.

3.Tips for boosting basal metabolic rate

There are several ways to boost BMR and increase energy expenditure, even as we get older. These include:

Resistance training: Resistance training, or weightlifting, can help increase muscle mass, which in turn can increase BMR. Aim for at least two sessions per week, focusing on major muscle groups such as the legs, back, chest, and arms.

Protein intake: Consuming adequate amounts of protein can help maintain and increase muscle mass, leading to an increase in BMR. Aim for at least 0.8 grams of protein per kilogram of body weight per day.

Exercise: Moderate aerobic exercise can help increase cardiovascular function, leading to an increase in BMR. In addition, high-intensity interval training (HIIT) can also increase BMR by increasing energy expenditure after exercise.

Sleep: Lack of sleep can decrease BMR. Aim for at least 7-8 hours of sleep per night to promote a healthy metabolism.

Diet: Eating a balanced diet can help regulate BMR. Consuming adequate carbohydrates can provide energy to maintain BMR. In addition, certain substances in foods, such as caffeine and capsaicin, can increase BMR.

Conclusion:

Basal metabolic rate is the minimum amount of energy required by the body to maintain basic functions at rest, and it decreases with age due to changes in muscle mass and hormonal changes. However, there are several ways to increase BMR and promote a healthy metabolism, including resistance training, protein intake, exercise, sleep, and diet. By incorporating these tips into your lifestyle, you can increase your body's energy expenditure and reduce the risk of weight gain and other health problems associated with age-related changes in BMR.
