What is Metabolism and How to Speed It Up

metabolic process

There are many articles online about losing weight by increasing or decreasing metabolism. However, most are written unambiguously, while the truth is not so certain. Let us learn what is metabolism exactly and how do you use it to lose weight.

What is Metabolism?

Our body is a huge and complicated living structure. There are millions of processes happening every second. All these processes require energy that is taken from calories.

Therefore, metabolism means the calories transformation into energy.

However, metabolism is not simply a digestion. It is a complex process that is hard to control. It includes diet, physical exercises, sleep – everything happening to your body. All the components affect metabolism differently; and all of them are affected by metabolism.

What is Metabolic Rate?

To understand what is metabolism you need to learn about metabolic rate. In general, this rate means how fast your body burns the calories it gets. You might think that with a higher metabolic rate you lose weight faster. However, it is much more complicated. We will discuss that further.

Your body needs energy for all the vital activities: breathing, maintenance of heat, heartbeat, blood circulation and coagulation, internal organs functioning etc.

However, much more energy is needed for your daily activities: walking, jogging, swimming, even shopping. Depending on what you do during a day, your metabolism varies. That is why you need to know some base numbers so that to be able to control the metabolism. It is where BMR come in hand.

BMR (basal metabolic rate) is a number of calories you regularly burn per day. Knowing this number, you can calculate how many calories to consume for weight loss. It is rather hard to measure BMR at home, as it requires some restricted conditions. However, you can use the Mifflin-St Jeor equation to calculate it yourself:

For men:

BMR = 4.55 × weight (lbs) + 15.86 × height (in) – 5 × age (y) + 5

For women:

BMR = 4.55 × weight (lbs) + 15.86 × height (in) – 5 × age (y) – 161

The number you get is the amount of calories you burn a day. This means that if you consume the same amount, your weight will not change. Notice that this value is the metabolism if you are resting the whole day.

Depending on your lifestyle, multiply it by:

  • 1.2 for sedentary lifestyle;
  • 1.375 for light exercise 1-3 days a week;
  • 1.55 for moderate exercise 3-5 days a week;
  • 1.725 for hard exercise 6-7 days a week;
  • 1.9 for very hard exercise and physical job.

Examples of Metabolism Rates

To give you an understanding on how to use the formula, let us consider a few examples.


  1. Say, your weight is 160 pounds. You are a 25 years old female with a height of 5 feet and 10 inches. According to a formula, your BMR is 1551 calories per day. If you are moderately active (exercising 3-5 days a week), your body burns 2404 calories per day.
  2. With a weight of 200 pound, a height of 6 feet and an age of 40, your BMR would be 1689. With a sedentary lifestyle, you burn 2027 calories per day.
  3. An 18 years old female with 120 pounds of weight and 5 feet 30 inches height has a BMR number equal 1722. Being very active (6-7 days of exercises per week), she burns 2971 calories per day.

Metabolism and Weight Loss

Considering mentioned, people come to conclusion that if they consume less calories than BMR, they will lose a proportional weight. However, metabolism does not work this way.

If you start eating less your body will adjust to a new diet. Therefore, BMR will slow down to meet the level of calorie intake.

As a result, you will have less energy, your concentration will lower and you will not rest when sleeping. These processes may lead to a weight gain. Therefore, it is a much better idea to increase your metabolism.

Summing up, eating less will not help you lose weight. You need to make your metabolism rise. As it happens, more calories are needed for your body to function. Controlling your diet, you can manipulate the weight loss.

Can You Increase Your Metabolism?

The answer is ‘yes’. High metabolism is associated with a healthy lifestyle; therefore, you should increase it. However, it is hard to perform nowadays.

The thing is many products we consume do not contain enough nutrients.

We eat a lot, but do not get much vitamins from the food. As a result, the body thinks we do not consume enough nutrients and lowers the metabolic rate. It leads to weight gaining, as many calories are turned into fat.

How to Boost Metabolism Naturally

First of all, change your diet. Healthy food is one of the most important things affecting your body. To make the BMR increase, you have to consume more vitamins and nutrients. As your cells receive them, the brain knows that there is a ‘good’ period and it does not need to save calories for later.

Secondly, do some exercises every day. They make you burn calories, so the BMR naturally increases. If you do not eat more than before starting to exercises, the body will have to get energy from fat. Moreover, exercising makes energy go to muscles.

Thirdly, it is a good idea to consume some supplements and vitamins. As we have mentioned, modern food from supermarkets is not as healthy as it is meant to be. Therefore, you need to get nutrients somewhere.

Foods that Boost Your Metabolism

As we have just learnt, changing your diet is the most important step to increasing metabolic rate. Therefore, stop eating any junk food (especially with a high concentration of cholesterol), do not drink much alcohol.

Add these products to your ration:

  1. Whole-grain products. These foods contain a lot of fiber. Your body spends many calories to digest it, so the metabolic rate increases. Whole-grain products preserve all natural microelements and vitamins. To start your day right, eat oatmeal for breakfast. It helps keep the balance of sugar in blood as well.
  2. Beans (peas, garbanzo beans, lentils etc.) These plants contain starch that is also hard to digest. In addition, it cleanses the intestines, so your diet normalizes. All beans are very nourishing and highly calorized. However, there are no harmful fats in them.
  3. Boiled chicken contains high amounts of protein, so it is ideal for accelerating metabolism. Amino acids are useful for your body, especially muscles. Eating chicken meat can help you increase metabolic rate up to 50%!
  4. Many kinds of fish and seafood are high in vitamins. Moreover, they help lower the amount of leptin in your body. This hormone affects metabolism and leads to weight gaining. The less you have, the easier it is to increase BMR.
  5. Grapefruit and other citrus fruits. Grapefruit contains a lot of water. It is low-calorized, almost free of fats and proteins, but full of vitamins. In addition, it contains half the daily intake of vitamin C. Grapefruit is one of the most effective remedies against fat. All citrus fruits stimulate metabolism nicely due to a unique set of vitamins, microelements, fruit acids and fiber.
  6. Apples stimulate the metabolism in your body. They are necessary for good health as well. To speed up your metabolism, eat a few apples a day. In this case, it is desirable not to clean them from the peel, since it contains a lot of vitamins and nutrients.
  7. Dairy products are powerful stimulants of metabolism. Scientists believe that this effect is due to the high content of calcium in them, because its deficiency is a real threat to proper metabolism. If you eat dairy products three times a day, you can accelerate the metabolism up to 70%.
  8. Spices: ginger, cinnamon etc. To diversify your diet, use some spices. They both help make the dish tasty and can increase your metabolism up to 10%.
  9. Spicy peppers (such as Carolina Reaper) contain a substance called capsaicin, which can significantly affect the metabolism. It is found in many types of peppers. Food, seasoned with hot pepper, accelerates the metabolic rate by 25%. The effect will last several hours after eating.
  10. Spinach is a nice metabolism catalyzer. It contains a lot of manganese, which is needed for a proper metabolic rate. There are also many other useful features of this plant, so it is all beneficial for your body.

You can eat any food that contains these vitamins as well:

  1. Vitamins B1, B2, B6, B12. All these are good for any diet. They help increase metabolism nicely. The other important thing about these vitamins, you can hardly consume too much.
  2. B4 vitamin. It helps to digest fats and removes cholesterol from blood, therefore increasing the BMR. This vitamin is necessary for a low-calorie diet.
  3. Coupled with choline, it contributes to the processing of fats. However, ask your doctor before consuming this vitamin as is.
  4. Vitamin C. It prevents the accumulation of glucose in the body, turning it into energy. The consumption of this vitamin improves metabolism a lot.
  5. Vitamin A. It promotes a better digestion of iodine, which is known for its beneficial effect on the function of the thyroid gland. The normal operation of this organ directly affects your metabolism.
  6. Vitamin D. It is used in building new muscles, so the more vitamin D you consume, the more calories will be used directly.
  7. Calcium is beneficial for many features, including metabolism increasing. It also prevents the accumulation of fats.
  8. Chromium perfectly copes with the processing of carbohydrates and removes the feeling of hunger. This element speeds up the metabolism, and is responsible for the level of sugar in the blood.
  9. Folic acid affects the acceleration of metabolism, strengthens the immune system and helps to cleanse the body.
  10. Omega-3 fatty acids regulate the leptin level. This means they can directly affect the metabolism in your body.

Supplements to Speed Up Metabolism

There are also some ready supplements for metabolism increasing. However, using them may not be beneficial for you. Consult with your doctor or personal trainer before including any to your diet.

Metabolism Boosters for Men and Women: Are They Different?

Metabolism is a complex process, as we have learnt. It is affected by many factors, so male and female metabolism varies. Even the BMR formula is different. Therefore, all the named ways of increasing metabolism will help differently.

However, all of them are equally useful. This means the foods or exercises we have discovered have no contraindications for any gender.

Changing your metabolic rate is a personal thing, so a gender does not affect it as much as many other factors do, such as habits, hormonal background etc.

If you want to lose some weight or just help your body stay healthy, you should try to increase your metabolic rate. To do so, you need to change your lifestyle. Everything we have mentioned works if done together. Therefore, eat healthy food, do some exercises and your metabolism will naturally normalize.
