A high genehics means geneticd need to geneetics in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
A person with a "low" or slow metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight. Lean people tend to be more active during everyday activities than people who are overweight.
They may "fidget" more — that is, they tend to be in motion even when engaged in non-exercise activities. Whether this tendency to move more or less is genetically programmed or learned remains uncertain.
But it can add or subtract hundreds of calories each day. Obese people expend more calories, on average, than lean people during most activities, in part because it takes more effort to move around.
But they tend to be more sedentary, which makes it harder to get rid of body fat. It's part truth and part myth that metabolism is the key to weight. The rising tide of obesity in this country cannot be blamed entirely on an inherited tendency to have a slow metabolism.
Genes do not change that quickly. Something environmental — particularly, changes in diet and exercising too little — are much more likely culprits.
Age can be a factor, too, although new evidence suggests metabolism reaches a peak earlier in life and slows down much later than previously thought. The reality is that for most people, excess weight is not all due to bad luck, thyroid trouble or some other unexplained, uncontrollable external factor.
For most of us, calories in, calories out has a strong influence on changes in weight over a lifetime. Regardless of whether your metabolism is fast or slow, our bodies are designed to store excess energy in fat cells. So, if you eat and drink more calories energy "intake" than your body expends energy "output" you will gain weight.
On the other hand, if you eat and drink fewer calories than are burned through everyday activities including exercise, rest and sleepyou'll lose weight. Our bodies are also programmed to sense a lack of food as starvation. In response, our BMR slows down, which means fewer calories burned over time.
That's one reason why losing weight is often difficult. Perhaps the most remarkable thing about all of this is how little our weight tends to change from day to day. In fact, only a few excess calories each day could lead to significant weight gain at the end of a year.
For example, eating an extra apple each day could lead to a weight gain of nearly 9 pounds by the end of one year! Similarly, even a small reduction in calories each day could lead to remarkable weight loss.
Eliminating dessert one day a week would lead to weight loss of nearly six pounds in a year. Many theories exist to explain what controls the amount of food a person eats, when they feel full and why they eat past the point of feeling full.
These factors also play a role in determining one's ultimate weight. One theory is that each of us has a set point — a weight at which the body is "happy. That may be another reason it is so hard to lose excess weight.
But how that set point is determined and whether there truly is such a mechanism remain uncertain. When it comes to weight, metabolism is important and does have a genetic component. Whether you can change your metabolic rate, however, is a matter of considerable debate.
Clearly, you can change how you balance the calories you take in against the calories you burn up through activity, which can change your weight. Did You Know?

How fast an organism carries out various vital functions is of fundamental importance to its ecological and evolutionary success. However, the rates of an organism's activities may be relatively slow or fast, for reasons that are incompletely understood. Because all biological processes require metabolic energy, their rates are often paralleled by the rate of metabolism, which constitutes all of the biochemical reactions by which energy and materials are transformed for various activities and structures. One of the most important intrinsic factors affecting MR is body size. Relationships between MR and body mass BM among individuals, populations or species are typically so strong and regular that they can often be well described by simple power or log-linear functions. This is particularly the case in:. Table 1. Datasets included in this study. View Large. View large Download slide. Table 2. Table 3. In our sample of 11 paired estimates, b A and b P were significantly correlated Fig. There are many reasons why this assumption should be avoided, just as a phenotypic correlation r P estimate is generally not an accurate indicator of r A Kruuk et al. The correspondence between b A and b P depends on the relative amount of co variance for the genetic versus other components of the total phenotypic covariance of MR and BM. In a simplified example in which the only sources of co variance between BM and MR are genetic and residual i. no sources of common environment variance , then:.

For most of us, calories in, calories out has a strong influence on changes in weight over a lifetime. Regardless of whether your metabolism is fast or slow, our bodies are designed to store excess energy in fat cells. So, if you eat and drink more calories energy "intake" than your body expends energy "output" you will gain weight. On the other hand, if you eat and drink fewer calories than are burned through everyday activities including exercise, rest and sleep , you'll lose weight. Our bodies are also programmed to sense a lack of food as starvation. In response, our BMR slows down, which means fewer calories burned over time. That's one reason why losing weight is often difficult. Perhaps the most remarkable thing about all of this is how little our weight tends to change from day to day.

These factors also play a role in determining one's ultimate weight. One theory is that each of us has a set point — a weight at which the body is "happy. That may be another reason it is so hard to lose excess weight. But once you start moving around, eating, and thinking, your body needs more fuel in the form of calories total caloric expenditure. When it comes to weight loss, most people research ways to improve their metabolism. But keep in mind, genetics play a significant role, and could explain some of your struggles or plateaus. There are many factors that determine weight even outside of metabolism. Endocrinologist Kaitlin Love, MD , explains that genetics drive our weight more than we think. So, when trying to lose weight, you have a team of factors as to why you might be struggling. These include how our hunger and appetite hormones function, causing a tendency for increased food intake. Also, how well we absorb and store calories, the type of fat our bodies store, and metabolism, among others. Many of these factors are outside our control. You can add more exercise and muscle mass to improve your metabolism. But much of what determines weight comes down to our gene makeup based on past generations. There are other factors which we have no say in, like our environment while growing in the womb and even during infancy and early childhood. Researchers are still learning about genetic factors that determine weight. This gene seems to cause a predisposition for increased food intake and may be important for determining the type of fat our bodies store. Our genes are learning to adapt to this new lifestyle, which will be passed along to our kids. Our bodies need a specific amount of nutrients to run. Protein, fats, and even carbohydrates are turned into calories for this fuel. When we follow trends such as the ketogenic diet and intermittent fasting, our bodies can compensate over time for a low-calorie diet. Once you add an activity such as walking to the bathroom from the couch, your body adds additional calories to run our muscle cells. Other factors that play a role in your metabolism:. You lose muscle mass as you get older, so your metabolism begins to slow down, and you burn fewer calories. Your body can reduce your basal metabolic rate even lower than the calories it previously needed to drive you back to a higher weight, making it hard to lose weight. Hormones also play into this sneaky behind-the-scenes energy machine. We're born with appetite hormones like leptin that decrease our appetite, and hunger hormones like ghrelin, which increase it. |
| Actions for this page | We can also blame stress and lack of sleep for contributing to weight gain due to the hormone cortisol. This is why shift workers tend to have weight issues as they have varying cortisol levels. When you have large amounts of this hormone, your body begins to store more fat and increase food cravings. It also affects your blood pressure and blood sugar, and it is influenced by your sleep cycle. And when they have days off, they want to socialize during the day, forcing their sleep schedule back to nights. This disruption of normal sleep-wake hours leaves a messy hormonal balance as well as promotes bad eating habits. Love recommends eating at normal meal times during the day to make the cortisol system happy and help improve your metabolism. Intermittent fasting works for weight loss and is comparable to calorie-restricting diets, but try the 11 a. schedule first. Your thyroid can mess things up, too. Women want to bounce back to their former bodies after pregnancy. Because of the physiologic changes to tissues in pregnancy, it is normal to gain a few pounds after having a child. Major obstacles for weight loss for many new moms are also losing sleep and being busier than before. There tends to be less time for exercise and healthy food choices during this huge life stage. Several factors contribute to this, including age, reduced muscle mass, and fewer activities. Reduction in estrogen levels after menopause also translates into changes in body composition more abdominal fat , mood changes, and sleep disruptions. As you lose muscle mass, it lowers your total energy expenditure, making it easier to gain weight. The goal is to find a balance of calories that work for your body. Losing weight can be frustrating. Increasing your movement throughout the day will boost your total caloric expenditure. You need high energy expenditure to keep weight off. HIIT workouts high-intensity interval training have become more popular over the last couple of years, increasing the calorie burn in one workout. But any activity is good for you! Take a short, brisk walk before work or during lunch to boost your metabolism. Your diet is most important for weight loss, so monitor your calorie intake, and find a diet, or better yet, a lifestyle change, that is sustainable. Good blog! I have a concern.

How Metabolism Works Our bodies need a specific amount of nutrients to run. A Chemical Reaction Hormones also play into this sneaky behind-the-scenes energy machine. Women and Big Life Events Women want to bounce back to their former bodies after pregnancy. People with the GG genotype were found to have lower energy expenditure, higher BMI, and higher fat mass compared to people with the AA genotype. This is seen in American Indians. A number of factors other than genetics influences metabolic rate. These include — Age: Metabolism decreases with age due to gain in fat, loss of muscle, and decrease in physical activity. This means that the metabolic rate will also decrease with age. People with more lean muscle tissue and lesser fat have a higher RMR. Fasting, starving, or crash dieting leads to loss of lean muscle mass and a decrease in RMR. Working out can help you stay fit and healthy and increase your metabolism, thereby increasing the resting metabolic rate. Here are a few things that you can do to increase metabolic rate: — Include plenty of proteins in your meal. It leads to a rise in the thermic effect of food, which is the extra calories needed to digest and absorb the nutrients in food. It also prevents muscle loss due to dieting and increases your metabolism. Research shows that it helps boost metabolic rate after training. It also helps combat the drop in metabolism that occurs after weight loss. Sleep deprivation has negative effects on metabolism and is a risk factor for obesity.

Catabolism — the breakdown of food components or nutrients into simpler form to produce the energy needed for daily functioning Some people have a faster metabolism than others. Metabolic Rate and Exercise Exercise helps you maintain weight and also can help change your metabolic rate. Estimating Metabolic Rate BMR is usually estimated through the Harris-Benedict formula revised in UCP1 Gene The UCP1 gene encodes the uncoupling protein, which plays a role in generating heat by allowing fast substrate oxidation and lower ATP production in brown adipose tissue. GPR Gene The GPR gene encodes a protein called G-protein coupled receptor , which is highly expressed in the brain. Non-Genetic Factors That Affect Metabolic Rate A number of factors other than genetics influences metabolic rate. Boosting Your Metabolic Rate Working out can help you stay fit and healthy and increase your metabolism, thereby increasing the resting metabolic rate. Summary Resting Metabolic Rate is the rate at which your body burns energy when at rest. Training and high-intensity workouts can boost your metabolism and metabolic rate. Exercise also increases muscle mass, which boosts metabolic rate. Variations in certain genes are found to affect metabolic rate. The AA genotype of SNP rs found in the UCP1 gene is associated with a higher metabolic rate and slower weight gain. The G allele of SNP rs found in the GPR gene is associated with lower energy expenditure. Non-genetic factors like age, gender, diet, body temperature, and body composition can lead to changes in your metabolic rate. Metabolic rate can be increased by increasing the intensity of exercise, lifting weights, resistance training, and eating a protein-packed meal. Newsletter Form 1 Name. Related Posts.

You no doubt have heard of metabolism and may even have a vague idea of what it is. But there are a lot of myths related to the impact metabolism has on your health, especially in terms of weight loss. In simple terms, metabolism is the internal process by which your body expends energy and burns calories.
This process works at different intensities in different people. How fast your metabolism works is determined mostly by your genes.
Chih-Hao Lee, professor of genetics and complex diseases at Harvard's T. Chan School of Public Health. Age also affects metabolism, as it can slow over the years, even if you start out with a fast metabolism.
Differences in metabolism speed are evident in how easy or hard it is for people to gain or lose weight. A slow metabolism burns fewer calories, which means more get stored as fat in the body; that's why some people have difficulty losing weight by just cutting calories.
A fast metabolism burns calories at a quicker rate, which explains why some people can eat a lot and not gain extra pounds. But you can't entirely blame a sluggish metabolism for weight gain, says Dr.
Is it possible to speed up a naturally slow metabolism, or rev up one that has become sluggish over time? That, along with adopting a healthier diet and making sure you get enough exercise, may give people the extra push they need to lose and maintain weight.
Pick up the pace. Add some high-intensity interval training to your regular routine. After a period of interval training, your metabolism can stay revved up for as much as a full day. For example, when you're walking or jogging on a treadmill or outside, speed up for 30 to 60 seconds, and then slow to your usual pace; repeat the cycle for eight to 12 minutes.
Eat protein and do weight training. Your metabolism increases whenever you eat, digest, and store food, a process called thermic effect of food. Protein has a higher thermic effect compared with fats and carbohydrates because it takes longer for your body to burn protein and absorb it.
It's not clear how much of an effect protein has on metabolism, but studies suggest the best approach is to combine adequate protein intake with weight training, which increases muscle mass — and that also can boost metabolism. Drink green tea.
Studies have found green tea contains a compound called epigallocatechin gallate, which may increase the calories and fat you burn. A meta-analysis published in Obesity Reviews found that consuming about milligrams of epigallocatechin gallate the amount in about three cups of green tea helped boost metabolism enough to burn an average of extra calories a day.

Thanks for visiting. Overview Genes influence your weight by their effect on: How calories are used energy metabolism. Some people use calories efficiently—they need fewer calories to fuel the body, which can result in "leftover" calories being stored as fat.
Other people use calories less efficiently—they need more calories to fuel the body, so there are fewer leftover calories to store as fat. Basal metabolic rate BMR , which is how much energy you burn when you are at rest. If you have a lower BMR, it is easier to gain weight.
Your BMR can change slightly in response to certain conditions. For example, starvation or very low-calorie diets decrease your BMR, because you lose muscle as well as fat. Muscle increases your resting metabolic rate, so losing too much muscle reduces metabolism.
Fever and severe physical stress, such as recovery from surgery or from extensive burns, increases your BMR. Body signals. Hunger, fullness satiety , and appetite are body signals that tell you how much to eat.
These signals also can be influenced by the environment and can be ignored for short periods of time. Hunger is a normal sensation growling in your stomach, feeling hunger pangs that makes you want to eat. It is partially controlled by a region of your brain called the hypothalamus , your blood sugar glucose level, how empty your stomach and intestines are, and certain hormone levels in your body.
Satiety is a feeling of fullness and satisfaction. Stretch receptors in the stomach send signals to the brain that the stomach is filled. Increased blood sugar glucose , the activity of the hypothalamus, and the presence of food in the intestines all contribute to satiety.
Appetite is a desire for or an interest in food that is associated with the sight, smell, or thought of food. Appetite can override hunger and satiety, such as when you continue to eat even after you feel full.
You can also have no appetite for food even though you are hungry, such as in a stressful situation or during an illness. Set point. This theory suggests that your body tries to keep your weight within a specific range, called your set point. The range seems to be influenced by your genetic makeup.
But your actual weight within that range is influenced by your lifestyle or environment. Your set point adjusts to a new level when it is maintained over time and can be altered by overeating, exercise, some medicines, and some brain conditions.
Fat distribution. Typically, men store fat in the abdomen while women store more in the hips and thighs. As women age, more fat is stored in the abdomen.

The amount of energy, measured in kilojoules kJthat your body burns at any given time is affected by your metabolism. Achieving or maintaining a healthy weight is a balancing act. If we regularly eat and drink more kilojoules than we need for our metabolism, we store it mostly as fat. Most of the energy we use each day is used to keep all the systems in our body functioning properly.
