This article reviews why some people have fast metabolism and how you can speed up your metabolism to burn more calories. On the other hand, those with fast metabolism burn more calories and are less likely to accumulate a lot of fat. The speed at which it runs varies by individual. Those with slow metabolism tend to have more leftover calories, which get stored as fat.

Your metabolism is the chemical engine that keeps you alive.

Metabolic rate is also known as calorie expenditure. It is the number of calories your body uses in a given amount of time.

Metabolic rate can be divided into several categories:

The speed of your metabolism is commonly known as metabolic rate. It’s the number of calories you burn in a given amount of time, also known as calorie expenditure. Metabolism is the reason some people can eat a lot without gaining weight, while others seem to need less to accumulate fat. Metabolism refers to all the chemical processes in your body. The faster your metabolism, the more calories your body needs. Multiple factors affect metabolic rate, or the number of calories burned. These include age, muscle mass, body size, and physical activity. Metabolic rates vary by individual, even among infants. However, it is unclear how much of this variation is due to genetics. Most of this variation is due to people’s age, as well as their environment and behavior. However, the role of genetics in these individual differences needs to be studied further. One thing is clear — not everyone is created equal when it comes to metabolic rate. In contrast, other studies show that formerly obese people have a 3–8% lower metabolic rate, on average, than those who have never been obese ( 10 , 20 ). Yet, studies indicate that obese people have higher metabolic rates irrespective of their muscle mass ( 18 , 19 ). Researchers note that this is partly because obese people have greater amounts of muscle to help support their extra weight ( 15 , 16 , 17 ). Interestingly, most studies show that obese people have a higher total and resting metabolic rate, compared to normal-weight individuals ( 12 , 13 , 14 , 15 ). Although genetics may contribute to these differences, scientists don’t agree on the extent to which they affect metabolic rate, weight gain , and obesity ( 10 , 11 ). In other words, some people are born with a faster metabolism than others. Metabolic adaptation or starvation mode is when metabolic rate slows down during a calorie-reduced diet or a fast. It varies between people and tends to be more pronounced among obese individuals. Starvation mode is probably partly affected by genetics, but previous weight loss attempts or physical fitness could also play a role ( 27 , 28 ). This metabolic slowdown is more pronounced in some people, especially those who are obese. The greater the slowdown, the more difficult it is to lose weight by dieting or fasting ( 21 , 25 , 26 ). The extent to which metabolic rate decreases during calorie restriction and weight loss is highly variable between individuals ( 21 , 22 , 23 , 24 ). Starvation mode is your body’s response to a calorie deficit. When your body doesn’t get enough food, it tries to compensate by reducing its metabolic rate and the number of calories it burns. Metabolic adaptation, also known as adaptive thermogenesis or “starvation mode,” may also play an important role in the development of obesity. Weight loss isn’t only about eating fewer calories. Effective weight loss programs also include strategies to speed up metabolism.

Here are eight simple methods.

1. Move Your Body

All body movement requires calories. The more active you are, the higher your metabolic rate. Even very basic activity, such as standing up regularly, walking around, or doing household tasks, makes a major difference in the long run. This boost in metabolic rate is technically known as non-exercise activity thermogenesis (NEAT).

In severely obese individuals, NEAT may account for a significant portion of daily calorie expenditure due to the extra weight they have to carry around ( 3 , 29 ). There are several ways in which you can boost NEAT. If you spend a lot of time sitting, here are a few strategies:

Stand up regularly and walk around

Take the stairs whenever possible

Do household tasks

Fidget by bouncing your legs or tapping your fingers

Chew calorie-free gum ( 30 )

) Use a standing desk ( 31 )

If you have a desk job, using a standing desk may increase the number of calories you burn by 16% ( 32 ). Another 10-person study showed that spending one afternoon standing burned an extra 174 calories compared to sitting ( 33 ). Even seemingly insignificant activities like typing may increase your metabolic rate by 8% compared to doing nothing ( 32 ). In the same way, fidgeting can make a significant difference ( 34 ). One study found that people who sat motionless for 20 minutes temporarily increased their calorie expenditure by 4%, compared to when they lay motionless. In contrast, fidgeting while seated increased calorie expenditure by a whopping 54% ( 35 ). Regular exercise is highly recommended for anyone who wants to lose weight or improve their health. But even light activities like walking around, doing household tasks, or fidgeting can give you an advantage in the long run.

2. Do High-Intensity Workouts

One of the most effective forms of exercise is high-intensity workouts, also known as high-intensity interval training (HIIT). HIIT is when exercise involves quick and very intense bouts of activity, such as sprints or fast push-ups. It significantly speeds up your metabolism, even after the workout has finished — an effect dubbed “the afterburn” ( 36 , 37 , 38 ).

3. Strength Train

Another excellent way to speed up your metabolic rate is to strength train ( 39 , 40 ). In addition to the direct effect of the exercise itself, strength exercises promote the growth of muscle mass. The amount of muscle you have is directly associated with your metabolic rate. Unlike fat mass, muscle mass significantly increases the number of calories you burn at rest ( 5 , 41 ). One study showed that doing strength exercises for 11 minutes a day, three times per week, resulted in an average increase of 7.4% in resting metabolic rate after half a year — and an additional 125 calories burned per day ( 40 ). Old age is generally associated with muscle loss and drops in metabolic rate, but regular strength exercise can partially counteract this adverse effect ( 42 , 43 ). Similarly, a calorie-reduced weight loss diet often results in the loss of muscle mass and metabolic rate. Again, strength training may help prevent this decline ( 44 , 45 ). In fact, a study in overweight women showed that doing daily strength exercises on an 800-calorie diet prevented decreases in muscle mass and metabolic rate, versus those who didn’t exercise or only did aerobics ( 46 ).

4. Eat Protein

Eating adequate amounts of protein is essential if you want to build or maintain your muscle mass. But dietary protein also has other important qualities. All food leads to a temporary increase in metabolic rate, known as the thermic effect of food (TEF). However, this effect is much stronger after eating protein compared to carbs or fat ( 47 ). In fact, protein may increase metabolic rate by 20–30%, whereas carbs and fat cause a 3–10% increase or less ( 48 ). This boost in calorie expenditure may help promote weight loss or prevent weight regain after a weight loss diet ( 49 , 50 , 51 ). TEF is highest in the morning or during the first few hours after you wake up. For this reason, eating a large proportion of your daily calories early in the day can maximize the effect ( 52 , 53 ).

Eating high amounts of protein can also help counteract the loss of muscle mass and metabolic rate associated with weight loss ( 54 , 55 , 56 ).

5. Don’t Starve Yourself

While eating less is a key weight loss method, eating too little is usually counterproductive in the long term.

That’s because calorie restriction causes a decrease in your metabolic rate.

This effect is known as starvation mode or metabolic adaptation. It is your body’s way of warding off potential starvation and death. Research shows that consistently eating fewer than 1,000 calories daily leads to a significant drop in metabolic rate that sticks around even after you stop dieting ( 57 , 58 , 59 ). Studies in obese people suggest that the starvation response may significantly reduce the number of calories burned. For instance, one study indicates that this slowdown in metabolic rate spares up to 504 calories per day ( 60 , 61 ). Interestingly, intermittent fasting seems to minimize this effect ( 62 , 63 ).

6. Drink Water

Temporarily boosting your metabolic rate doesn’t have to be complicated. It’s as simple as going for a walk or drinking a glass of cold water. Many studies show that drinking water leads to an increase in the number of calories burned, an effect known as water-induced thermogenesis ( 64 , 65 , 66 ). Drinking cold water has an even greater effect than warm water, as this requires your body to warm it up to body temperature. Studies on this phenomenon provide varying results. About 16 ounces (500 ml) of cold water may cause a 5–30% increase in the number of calories burned for 60–90 minutes afterward ( 64 , 66 , 67 , 68 ). It seems that increasing your water consumption is also beneficial for your waistline. Several studies show that drinking 34–50 ounces (1–1.5 liters) of water daily may lead to significant weight loss over time ( 64 , 69 ). You can maximize these benefits by drinking water before meals, as it also fills you up and reduces calorie intake ( 70 ).

7. Drink Caffeinated Beverages

Although plain water is good on its own, caffeinated, low-calorie beverages, such as coffee or green tea, are useful as well. Controlled studies show that drinking caffeinated beverages can temporarily speed up your metabolic rate by 3–11% ( 71 , 72 , 73 , 74 ). However, this effect is smaller in obese people, as well as older adults. Additionally, seasoned coffee drinkers might have built up a resistance to its effects ( 75 , 76 ). For weight loss purposes, sugar-free beverages like plain, black coffee are best. Like water, cold coffee may be even more advantageous.

8. Get Good Sleep

Getting inadequate sleep is not only bad for your general health, but it may also slow down your metabolic rate and increase your risk of weight gain ( 77 , 78 ). One study showed that metabolic rate decreased by 2.6% when healthy adults slept for only four hours per night for five days in a row ( 77 ). Another five-week study determined that sustained sleep disruption, along with irregular sleeping times, reduced resting metabolic rate by 8%, on average ( 78 ). Accordingly, lack of sleep is associated with an increased risk of weight gain and obesity ( 79 , 80 , 81 , 82 ).
