Does Working Out Really Increase Metabolism?

You’ve probably heard that working out can help increase your metabolism. But does it really work? We’ll take a look at the science behind it.


Before we can answer the question of whether working out actually increases metabolism, it is important to understand what metabolism is and how it works. Metabolism is the process whereby your body converts food into energy. It includes all the processes involved in breaking down molecules into small pieces and using them to produce energy and other molecules. Working out has long been thought to play a role in boosting your body’s metabolic rate and, thus, its energy expenditure rate. This article will examine the effects of exercise on metabolism and how it affects overall health and well-being.

What is Metabolism?

Metabolism is the biochemical process your body undergoes to convert the food and drink you consume into energy. It helps maintain your body’s optimal performance and is vital for survival. Understanding what metabolism really is and how it works is key to understanding how exercise can affect your metabolism and overall health. Let’s dive into the details.


Metabolism is a term used to describe all the chemical reactions that take place in the body. It encompasses both construction – building of molecules and materials such as proteins and bone – and destruction, where digestive enzymes break down food molecules for used by cells for energy or for storage. The speed at which these reactions occur is referred to as metabolic rate, and the rate can vary widely from person to person based on several factors from age to energy output levels.

When people talk about increasing their metabolism with exercise, we are more often referring to how much energy their body expends when exercising versus how many calories they consume. Higher intensity levels work off more energy than lower-intensity activities, leading to an increase in metabolic rate over time with regular workouts. It is important to note that eating habits will determine total daily expenditure of calories infinitely more than exercise does.

Types of Metabolism

Metabolism is the set of life-sustaining chemical transformations within an organism that allow for the production of energy, growth and regeneration. Metabolism encompasses the breakdown of nutrients from food and its conversion into energy, as well as the creating and breaking down of certain molecules in cells. This complex process can be divided into two main types: catabolism and anabolism.

Catabolism is a process where larger molecules in cells are broken down into smaller ones, releasing energy which powers cell functions like growth and development. An example of catabolic metabolism is the breaking down of glucose from digested carbohydrates to produce ATP (adenosine triphosphate), a form of energy used by cells to fulfill cellular activities.

Anabolic metabolism consists of building or synthesizing complex molecules from simpler ones through condensation reactions, requiring energy input from catalytic enzymes or ATP. Examples include protein synthesis, such as muscle building, or membrane synthesis in red blood cell regeneration.

Both types of metabolism work together in harmony to establish equilibrium within an organism’s bodily systems, allowing for optimal health and homeostasis. Without these mechanisms functioning properly, organisms cannot survive due to insufficient amounts of fuel-like energy needed for all biochemical reactions required to stay alive.

The Role of Exercise in Metabolism

Exercise is widely known to have many health benefits, but can it really help to increase one’s metabolism? The answer is yes, with good evidence that an exercise program can help to boost metabolism. In this article, we will discuss the role of exercise in metabolism, and look at some of the ways in which working out can affect a person’s metabolism.

How Exercise Affects Metabolism

One of the most widely known ways to increase metabolism is through physical activity. Exercise increases the number of calories your body uses in order to sustain your basal metabolic rate, or BMR. The more active you are, the higher your BMR will be over time. Your muscles will also grow in size and strength, which means that even when you’re resting, you’ll still be burning calories as your body repairs and rebuilds them.

Exercising with specific exercises that focus on increasing muscle mass can be a great way to boost metabolism even more. This includes activities such as weightlifting, strength training and circuit training. Muscle tissue burns three times as many calories as fat cells do, so building muscle mass can further boost your metabolic rate throughout the day.

Other forms of regular physical activity such as brisk walking or jogging can also help to increase metabolism by improving cardiovascular fitness and endurance levels. This will ensure that you are burning more calories in less time when exercising and can keep your body burning calories for longer even after exercise is over.

Finally, it is important to remember that not all exercises are created equal; more intense forms of exercise tend to have a greater impact on metabolism than lower intensity regimens do. By incorporating high intensity interval training into your workouts on a regular basis, you can maximize calorie expenditure while minimizing total workout time — another helpful way to increase metabolism each day!

Benefits of Exercise on Metabolism

Exercise plays a key role in regulating metabolism and improving overall bodily health. When you perform regular physical activity, your body’s metabolism is increased; this is because exercise stimulates the release of certain hormones and proteins that cause cells to function more efficiently and burn more calories.

The benefits of exercise on metabolism extend beyond just calorie burning. It can help boost the production of endorphins, which are chemicals that naturally increase your energy level, improve focus and concentration and can even reduce stress levels. Exercise also helps strengthen your cardiovascular system, resulting in improved oxygen uptake to muscles while they’re at work. This will help you get the most from each workout session as well as promote better recovery post-exercise.

In addition to these metabolic benefits, regular exercise can help promote muscle mass development since it encourages protein synthesis in your body. This leads to higher lean muscle mass, which will then increase basal metabolic rate (the amount of energy you burn at rest). Exercise has further been shown to aid in weight control efforts by decreasing appetite through its effect on hormones such as ghrelin; this hormone helps regulate hunger levels but can be reduced following physical activity.

Exercising regularly not only increases metabolic rate in the short term but also leads to long-term improvements due to changes in body composition. For best results with increasing metabolic rate, try combining different types of exercise such as aerobic activities like running or walking with strength training exercises like push ups or sit ups; this way you’ll get a combination of calorie burning benefits along with muscular growth!

Other Factors That Influence Metabolism

While it is true that working out can help increase your metabolism and burn calories, there are other factors that can also have an impact on your metabolic rate. Your physical activity and diet are two important aspects that can influence your metabolism, but they are not the only ones. In this article, we will look at other factors and how they affect metabolism.


Diet is an important factor when it comes to metabolism. Eating a balanced diet that contains the essential nutrients and calories your body needs can help to increase your metabolism. Eating plenty of protein is especially important, as it helps promote muscle growth and healthy hormonal balance, both of which are necessary for a fast metabolism. Additionally, eating several small meals throughout the day instead of three large meals can help to boost your metabolism as well. Finally, drinking enough water throughout the day ensures that your body has enough fuel to perform all its necessary metabolic processes.


Age is an important factor that influences metabolism. Metabolic rate typically decreases with age due to a combination of decreased muscle mass and slowed hormonal activity. As people age, their bodies naturally produce lower levels of hormones responsible for regulating metabolic rate such as thyroid hormones, Human Growth Hormone (HGH), testosterone, and estrogen. A lowered metabolic rate therefore requires a balanced diet and regular exercise to maintain a healthy weight.

In addition, the body’s natural fat-burning process begins to slow as you age. Muscle strength and endurance also tend to decrease over time which can limit your ability to burn more calories through physical activity. Working out regularly can help maintain muscle mass and counteract the slowing down of your metabolic rate that often comes with age.

It is important for older adults or those who are prone to weight gain as they get older, to make lifestyle changes in order to maintain a healthy weight or lose weight if necessary. This includes exercising regularly and following a balanced diet that includes nutritious whole-foods while avoiding processed foods high in carbohydrates, sodium, and unhealthy fats. Additionally, getting enough sleep each night is essential for regulating hormones responsible for optimal overall health, including metabolic rate.


The genetic makeup of an individual often plays the biggest role when it comes to metabolism. Studies have been conducted over many years that have linked certain body types with certain metabolic rates, creating a general consensus that some people possess a natural advantage when it comes to burning calories. Genetic factors such as thyroid function and muscle mass play key roles in determining how quickly a person’s body works to convert food into energy, leading to faster or slower metabolisms. Not only can genetics influence baseline metabolism, but research is uncovering increasing evidence that genetics may be able to interact with environmental activities such as exercise and nutrition in ways that can further alter the speed of metabolism in individuals.


It is clear from the evidence presented that consistent physical activity has a positive effect on your metabolic rate. Exercise causes an increased demand for energy, which increases the calorie-burning potential of your body, leading to an increase in metabolism. However, there are other factors that contribute to how quickly you can burn calories such as dietary behavior and genetics. Therefore, it is important to be mindful of all lifestyle circumstances when trying to achieve your health and fitness goals.

In conclusion, regular physical activity is a key component to increasing your metabolism and controlling calorie intake over time. Additionally, it should be noted that it may take several months for exercise to significantly increase metabolism; so don’t get discouraged if results arrive slower than expected. With disciplined dieting and exercise habits, anyone can find success in their pursuit of a healthy lifestyle!
