Unlike age, which you cannot control, body composition is a factor you can actively manage to impact your BMR. Typically, men and women have different BMRs due to inherent biological differences, particularly in body composition and hormonal makeup.

Lifestyle choices, such as diet and exercise, can significantly influence BMR, regardless of gender. Genetic makeup is a crucial yet often overlooked component influencing Basal Metabolic Rate BMR.

Imbalances in key hormones can significantly alter how efficiently your body burns calories. Engaging in regular physical activity not only burns calories during the activity itself but also has a profound effect on your overall metabolism.

Your body works constantly to maintain a stable internal temperature, and variations in external temperature can impact how much energy is expended in this process.

Understanding the various factors that influence your Basal Metabolic Rate is a key step towards optimizing your health and wellness. From age and gender to genetics and physical activity, each element plays a distinct role in determining how efficiently your body burns calories.

Armed with this knowledge, you are now better equipped to make informed decisions and adopt lifestyle practices that can positively impact your BMR. Remember, small, consistent changes in your daily habits can lead to significant improvements in your metabolic health, paving the way for a more energetic and healthier life.

The three components of Basal Metabolic Rate BMR are genetic factors, age, and body composition. These elements collectively determine how efficiently your body burns calories at rest, influencing overall metabolic health. Five factors that can increase your Basal Metabolic Rate BMR are regular physical activity, building muscle mass, maintaining hormonal balance, exposure to cold temperatures, and a balanced, nutritious diet.

The single most important factor affecting Basal Metabolic Rate BMR is body composition, specifically the ratio of muscle to fat. Higher muscle mass significantly increases BMR, as muscles are more metabolically active than fat tissue. An optimal BMR for an individual supports their specific health goals and overall well-being.

How metabolic rate varies with body size and activity level. Key points:. Metabolism is inefficient and produces heat. Endotherms use metabolic heat to keep a stable body temperature, while ectotherms do not. The "baseline" metabolic rate of an animal is measured as the basal metabolic rate BMR for an endotherm or as the standard metabolic rate SMR for an ectotherm.

Among endotherms, smaller animals tend to have higher per-gram basal metabolic rates a "hotter" metabolism than larger animals. The same is true among ectotherms, though we can't compare between the groups. Metabolic rate varies with activity level. More active animals have a higher metabolic rate than less active animals.

Some animals enter a state of torpor in which their metabolism slows. Hibernation in the winter and estivation in the summer are forms of torpor. You may be used to thinking about metabolism in terms of human eating patterns.

However, metabolism isn't something that's unique to humans. So, every living thing has a metabolism, from a bacterium to a plant to you! There are general differences in metabolic rate among species, and the environmental conditions and activity level of an individual organism will also affect its metabolic rate.

Metabolism and heat production. It's probably not news to you that animals such as humans need food as a source of energy. But why is this the case? The molecules in your breakfast, lunch, or dinner have energy stored in their chemical bonds.

Some of your body's metabolic reactions, like the ones that make up cellular respiration , extract this energy and capture part of it as adenosine triphosphate ATP.

This energy-carrying molecule can, in turn, be used to power other metabolic reactions that keep your cells running. A diagram shows a drawing of various foods at the top. Three arrows point from the drawings of the food to the words Proteins, Carbohydrates, and Fats.

An arrow leads from each of these words to a box labeled Cellular respiration. Below the box, a curved arrow points from the top of the word A D P to the top of the word A T P. Molecules from food are also used as building blocks for the structures of your body.

For instance, proteins from your food are broken down into their component parts amino acids and may be used to build new proteins in your own cells. If you eat more than enough food to replenish the energy you use, food energy may also be stored as glycogen a chain of linked glucose molecules or as triglycerides fat molecules for later use.

The business of extracting energy from fuel molecules and using it to power cellular reactions is not a perfectly efficient process. In fact, no energy transfer can be perfectly efficient — that's a basic law of physics. Instead, each time energy changes forms, some amount of it is converted into a non-usable form.

In the reactions of an animal's metabolism, much of the energy stored in fuel molecules is released as heat. This is not necessarily a bad thing! Some animals can use and regulate their metabolic heat production to maintain a relatively constant body temperature.

These animals, called endotherms , include mammals, such as humans, as well as birds. Ectotherms , on the other hand, are animals that don't use metabolic heat production to maintain a constant body temperature.

Instead, their body temperature changes with the temperature of the environment. Lizards and snakes are examples of ectotherms.

Two line graphs side by side, each with Outside temperature degrees Celsius on the x axis and Body temp degrees Celsius on the y axis. The first graph shows a picture of a mouse and is labeled, Endotherms like the mouse generate metabolic heat to maintain internal temperature.

The graph shows a nearly horizontal line at 38 degrees Celsius with only a slight downward curve at the left side and a slight upward curve at the right side.

The second graph shows a picture of a snake and is labeled, Ectotherms like the snake have a body temperature that changes with the temperature of the environment. The graph shows a diagonal line trending upward from the point 5, 5 to the point 40, Metabolic rate.

The amount of energy expended by an animal over a specific period of time is called its metabolic rate. Metabolic rate may be measured in joules, calories, or kilocalories per unit time. You may also see metabolic rate given as oxygen consumed or carbon dioxide produced per unit time.

Oxygen is used up in cellular respiration, and carbon dioxide is produced as a by-product, so both of these measurements indicate how much fuel is being burned. In some cases, metabolic rate is given for the entire animal. Per-mass metabolic rates help us make meaningful comparisons between organisms of different sizes.

For an endotherm, the BMR is also measured when the animal is in a thermoneutral environment, that is, one where the organism does not expend extra energy above baseline to maintain temperature. For an ectotherm, SMR will vary with temperature, so any SMR measurement is specific to the temperature at which it's taken.

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. Another excellent way to speed up your metabolic rate is to strength train 39 , 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 , One study showed that doing strength exercises for 11 minutes a day, three times per week, resulted in an average increase of 7.

Old age is generally associated with muscle loss and drops in metabolic rate, but regular strength exercise can partially counteract this adverse effect 42 , 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 , 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 This boost in calorie expenditure may help promote weight loss or prevent weight regain after a weight loss diet 49 , 50 , 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 , Eating high amounts of protein can also help counteract the loss of muscle mass and metabolic rate associated with weight loss 54 , 55 , While eating less is a key weight loss method, eating too little is usually counterproductive in the long term.

This effect is known as starvation mode or metabolic adaptation. Research shows that consistently eating fewer than 1, calories daily leads to a significant drop in metabolic rate that sticks around even after you stop dieting 57 , 58 , 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 calories per day 60 , Interestingly, intermittent fasting seems to minimize this effect 62 , 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 , 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. It seems that increasing your water consumption is also beneficial for your waistline. Several studies show that drinking 34—50 ounces 1—1. You can maximize these benefits by drinking water before meals, as it also fills you up and reduces calorie intake Although plain water is good on its own, caffeinated, low-calorie beverages, such as coffee or green tea , are useful as well.

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 , For weight loss purposes, sugar-free beverages like plain, black coffee are best.

Like water, cold coffee may be even more advantageous. 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 , One study showed that metabolic rate decreased by 2.

Accordingly, lack of sleep is associated with an increased risk of weight gain and obesity 79 , 80 , 81 , There are numerous things you can do to boost your metabolism. These include drinking cold water, sipping on coffee, getting more sleep, exercising, and eating protein.

Objective: We partitioned the variance in BMR into within- and between-subject effects and explored the roles of FFM, FM, bone mineral content, sex, age, and circulating concentrations of plasma leptin, T3, and T4.

Design: This was a cross-sectional study of white adults from northeast Scotland, United Kingdom. Twenty-six percent of the variance remained unexplained. This variation was not associated with concentrations of circulating leptin or T3.
