Can You Increase Your Metabolism?
Your metabolism plays a key role in maintaining your body’s energy balance, influencing how many calories you burn both at rest and during activity. While your genetic makeup is a major factor determining your metabolic rate, that doesn’t mean you’re powerless to influence it. There are several lifestyle changes and habits you can adopt to boost your metabolism, which can be especially helpful if you’re looking to lose weight.
Understanding Metabolism
Metabolism is the process by which your body converts the food and drink you consume into energy.
This complex series of chemical reactions powers everything you do, from breathing and circulating blood to repairing cells and thinking.
Your body is always burning calories, even when you’re resting or sleeping, to maintain these vital functions. This energy expenditure is called your basal metabolic rate (BMR). In addition to BMR, your metabolism is influenced by:
Daily Activities: Walking, talking, and performing household tasks all contribute to calorie burning.
Physical Exercise: More intense activities like running, swimming, or weightlifting significantly increase calorie expenditure.
Together, these components determine the total number of calories you burn each day. While metabolism is largely influenced by genetics, there are lifestyle modifications you can adopt to help increase your metabolic rate.

Factors Affecting Metabolism
Metabolism is influenced by several factors, including:
Genetics: Your genetic makeup significantly impacts your metabolic rate. Some people naturally have a faster metabolism, while others have a slower one.
Age: As you age, your metabolism tends to slow down, partly due to a decrease in muscle mass.
Muscle Mass: Muscle burns more calories than fat, even at rest, making muscle mass a key determinant of metabolic rate.
Hormones: Hormonal imbalances, such as those involving thyroid hormones, can also affect metabolism.
Diet and Metabolism
Many people turn to dieting to lose weight, but overly restrictive diets can backfire by slowing down your metabolism. When your body senses a reduction in calorie intake, it may lower your BMR to conserve energy, interpreting the reduced intake as a potential threat of starvation. This is why losing weight can often be challenging—the body adapts to reduced calorie intake by burning fewer calories.
Instead of focusing on restricting calories, it’s more effective to choose foods that can support your metabolism. Research has found that certain foods can boost diet-induced thermogenesis (DIT), which is the energy your body uses to digest and process food. Some of the best foods for boosting metabolism include:
Foods That Boost Metabolism
Protein-Rich Foods: Foods like lean chicken, fish, beans, Greek yogurt, and nuts are rich in protein, which requires more energy to digest compared to fats or carbohydrates. Protein also helps preserve muscle mass, which is important for maintaining a higher metabolic rate.
Unrefined Carbohydrates: Fiber-rich foods, such as vegetables, fruits, whole grains, and legumes, take longer to digest, which increases energy expenditure and helps stabilize blood sugar levels.
Caffeine: Found in coffee and tea, caffeine can temporarily boost metabolism and increase the number of calories burned. Drinking about three cups of green tea, which contains a combination of caffeine and catechins, can help you burn around 100 extra calories per day.

Timing and Meal Frequency
Eating larger meals earlier in the day may also help boost metabolism, as DIT is generally higher in the morning and lower in the evening. Consuming balanced meals that provide sufficient fuel and nutrients throughout the day is key—instead of simply eating less, focus on eating nutrient-dense foods and spreading your calorie intake to keep your metabolism active.
Exercise and Metabolism
Physical activity plays a crucial role in boosting metabolism. There are two main types of exercises that can help enhance your metabolic rate:
Strength Training to Build Muscle
Strength training exercises are an effective way to boost your metabolism because they help build muscle tissue. Muscle burns more calories than fat, even when your body is at rest. The more muscle mass you have, the higher your BMR will be. Along with genetics, muscle mass is one of the strongest determinants of your BMR.
Â
Strength training also has an additional benefit known as excess post-exercise oxygen consumption (EPOC), or the "afterburn effect." After intense workouts, your body requires extra oxygen to restore itself to its resting state, which means you continue burning calories even after you’ve finished exercising.
High-Intensity Interval Training (HIIT)
Another type of exercise that can boost metabolism is high-intensity interval training (HIIT). HIIT involves alternating between short bursts of intense exercise and brief periods of rest or low-intensity activity. Research suggests that HIIT can elevate your metabolism for hours after a workout, increasing your overall calorie burn.

Lifestyle Tips to Boost Metabolism
In addition to diet and exercise, there are other lifestyle habits that can support a healthy metabolism:
Stay Hydrated: Drinking enough water is essential for optimal metabolic function. Dehydration can slow down your metabolism.
Get Enough Sleep: Lack of sleep can disrupt hormone levels and negatively impact your metabolism. Aim for 7-8 hours of quality sleep per night.
Manage Stress: Chronic stress can lead to hormonal imbalances that slow metabolism.
Practicing stress-reducing activities like yoga, meditation, or deep breathing can help maintain a healthy metabolic rate.

 Final Thoughts on Boosting Metabolism
Â
While your genetics play a significant role in determining your metabolism, there are several strategies you can use to give it a boost. Incorporating strength training, HIIT, and a diet rich in protein and unrefined carbohydrates can help increase your metabolic rate. Additionally, staying hydrated, managing stress, and getting enough sleep are important for supporting a healthy metabolism.
Remember that the key to boosting your metabolism is a balanced approach that includes nutritious eating, regular physical activity, and maintaining muscle mass. By making these lifestyle changes, you can take control of your metabolism and work towards your health and fitness goals.
