How to Increase Metabolism
March 15, 2025

The term “metabolism” describes the chemical reactions in your body as it transforms food and liquids into energy. Energy is produced and released by a complicated mechanism that mixes calories and oxygen. This energy fuels body processes.
The Functions of Your Metabolism
Even while your body is at rest, your metabolism continues to operate. It continuously supplies energy for fundamental bodily processes like:
- Breathing
- Circulating blood
- Meal digestion
- Growing and repairing cells
- The control of hormone levels
- Regulating body temperature
Natural Way to Improve Metabolism
It is possible to increase your metabolism quickly with several simple and efficient techniques, many of which only need minimal dietary and lifestyle changes.
Build Muscle
Even when you are not doing anything, your body continuously burns calories. As a result, people with more muscle have substantially higher resting metabolic rates. While each pound of fat only burns two calories daily, every muscle takes roughly 6 calories daily to maintain itself. Over time, even a modest difference might build up. For example, your body’s muscles become active after a strength training exercise, increasing your metabolic rate daily.
Eat Enough
To lose weight quickly, some people reduce their caloric intake. Eating less, however, is a myth because your body can lose muscle if you don’t get enough calories. To save energy for essential processes, your body also slows burning calories when you eat less. To burn extra calories, consume a nutritious diet and exercise.
Eat Often and Normally
Your metabolic rate briefly rises after eating due to the digestion process. With this in mind, eating short, light meals every three to four hours makes sense. Long periods between meals might deprive your body and result in a calorie deficit. Additionally, leaving a lot of time between meals will eventually slow your metabolism. However, you should be careful when making your decisions because they affect how many calories you ingest. Remember to consume enough protein in your diet because, according to studies, it not only aids in muscle growth but also demands the most calories to be digested of all nutrients.
Stand Up More
Spending too much time sitting can adversely affect your health by decreasing calorie burn and potentially causing weight gain.
A 2018 review revealed that standing or moving at work was linked to lower cardiometabolic risk (CMR) scores, reduced body weight, fat percentage, waist circumference, blood pressure (both systolic and diastolic), fasting triglycerides, total/HDL cholesterol, and insulin levels. However, stepping rather than just standing led to more significant improvements in lowering systolic blood pressure and insulin resistance.
If you have a desk job, incorporate short breaks to stand up and walk around throughout the day. Incorporating regular walks or using a standing desk can help minimize extended periods of sitting. A 2020 study also found that standing and walking periodically lowered blood sugar and insulin levels.
Reduce Stress
The stress hormone cortisol is produced due to ongoing stress. Our appetite is also controlled by cortisol. Thus, a rise in stress levels can directly impact how much food we eat and slow our metabolism.
Utilize meditation to help you relax. A quick stroll across the park or engaging in your favorite pastime might also help to lower tension. Find out which exercises work best for reducing stress.
Get Enough Sleep
Good sleep is directly related to our metabolic rate, according to research. A quick metabolism is a sign of good sleep, while a sluggish metabolism is a sign of poor sleep.
Inadequate sleep also interferes with the release of certain hormones. For instance, it has a detrimental effect on ghrelin levels (the hunger hormone).
This has a deleterious effect on metabolism and may lead to eating disorders. Even though everyone needs a different amount of sleep, multiple studies have found that most adults should get at least 7 hours of rest every night.
Stay Hydrated for Optimal Metabolism
Drinking enough water is crucial for overall health and proper metabolic function. A 2016 study found that consuming 500 mL of water increased fat oxidation at rest, suggesting hydration may support metabolism. While it may not directly boost metabolic rate, staying hydrated can aid digestion and weight management.
Spice Up Your Meals
Spicy meals contain natural compounds that might accelerate your metabolism. For example, cooking with a spoonful of chopped red or green chili pepper can increase your metabolic rate. Although the effect is transient, eating spicy food frequently may have long-term advantages. Add red pepper flakes to stews, chili, and pasta recipes for a rapid boost.
Include Foods High in Protein in Each Meal
Compared to the breakdown of carbs and fats, proteins require more energy from the body. The thermic effect of eating is the result of this increased metabolism. Eating a lot of protein has been proven to speed up metabolism and enhance calorie expenditure considerably. Protein also promotes satiety, which reduces hunger cravings and consequent overeating.
Nutrition
Foods that can boost your metabolic rate should be a regular diet. Avocado, red fruits (rich in antioxidants), pineapple, kiwi, lemon, ginger, cinnamon, grapefruit, dairy products (high in protein), fish, eggs, lentils, apples, dairy products (high in protein), etc. Make sure you’re exercising regularly and consuming a nutritious diet.
Sip Some Black Coffee
If you drink coffee, you will appreciate the benefits of your energy and focus. A temporary increase in your metabolic rate may be one of the advantages of using coffee in moderation. In addition, when you work out, caffeine can make you feel less exhausted and improve your endurance.
Support Your Gut Microbiome
The microbes in your gut are essential for digestion and maintaining overall health. Research shows that gut bacteria influence how your body processes food, affecting blood sugar, fat storage, and metabolism.
Scientists have identified 15 “good” microbes linked to better metabolic control and 15 “bad” microbes associated with increased belly fat. While changing your diet won’t directly alter calorie burn, it can improve gut diversity, supporting heart health and digestion.
To nourish your microbiome, focus on a fiber-rich diet with diverse, whole foods to encourage beneficial bacteria.
Recharge With Green Tea
The benefits of caffeine and catechins, which have been demonstrated to stimulate the metabolism for a couple of hours, can be obtained by drinking green or oolong tea. According to research, consuming 2 to 4 cups of tea may encourage the body to burn 17% more calories for a brief period of moderately strenuous exercise.
Strength Training
Maintaining and even gaining muscle mass is possible with strength training. You’ll burn more calories throughout the day if you have more significant muscle. You can increase your muscle mass and speed up your metabolism by lifting weights, carrying around heavy things, or doing other exercises with weights on your body. However, your body also needs extra energy to maintain muscle mass. Compared to a pound of fat, which only requires two calories each day, each pound of muscle in your body needs roughly six calories daily. There are numerous methods for developing muscle.
Increase Your B Vitamin Levels
Include bananas, eggs, potatoes, spinach, peanut butter, etc., in your diet to obtain enough vitamin B. You can also take supplements to get your daily dose of B vitamins.
Conclusion
Metabolism is a complex process that affects energy production and overall health. While genetics play a role, lifestyle choices significantly impact how efficiently your body burns calories. Supporting gut health, maintaining muscle mass, and managing stress can contribute to a balanced metabolism. Making informed dietary and lifestyle choices helps optimize metabolic function, promoting long-term well-being.
Frequently Asked Questions
1. What are the signs of a slow metabolism?
Everybody is unique, and signs of a slow metabolism can vary from person to person. Common indicators may include ongoing fatigue, continuous headaches, weight gain, constipation, depression, thin hair, brittle nails, and dry skin.
However, only a healthcare professional can accurately evaluate your metabolism and identify the underlying causes of these symptoms.
2. Does hypothyroidism lower metabolism?
Yes, hypothyroidism lowers metabolism because the thyroid gland doesn’t produce enough hormones (T3 and T4) to regulate energy use. This slows metabolic rate, leading to fatigue, weight gain, and difficulty losing weight. Treatment with thyroid hormone replacement can help restore normal metabolism.
