Your metabolism, and your basal metabolic rate (sometimes referred to as just metabolic rate), is significantly influenced by genetics. That being said, a faster metabolism may be promoted over time by consistently building lean muscle mass and being cognizant of one's caloric intake.
People with more muscle mass often have faster metabolisms that burn more calories. Age: You lose muscle as you get older, which slows down the metabolism. Sex: Males tend to have faster metabolisms than females. They have more muscle mass, larger bones and less body fat.
Regular meals, sleep, and exercise may all help boost metabolism. Calories provide the energy the body needs, not only to move but also to breathe, digest food, circulate blood, grow cells, repair wounds, and even to think. The rate at which the body burns calories to produce this energy is called the metabolic rate.
Signs of a fast metabolism
You have a high body temperature, even when you are resting. You are often hungry or have an insatiable appetite, even after eating meals or snacks. You have an irregular menstrual cycle or you miss your period even though you aren't pregnant.
While having a fast metabolic rate is not necessarily good or bad in terms of health, making sure you take in enough calories to sustain yourself and nourish your body is important—while also striving not to take in too many calories, which can lead to an energy imbalance.
Internal symptoms of hypermetabolism include: peripheral insulin resistance, elevated catabolism of protein, carbohydrates and triglycerides, and a negative nitrogen balance in the body. Outward symptoms of hypermetabolism may include: Weight loss. Anemia.
There are many natural changes that happen with age that can slow down a woman's metabolism: Less muscle, more fat: Women naturally lose lean body mass – or muscle – as they get older. Men do too, but women have less to begin with, so hanging on to it takes more effort. Having less muscle decreases your metabolic rate.
Elevated body temperature: A fast metabolism can raise the body's core temperature, making people feel warm or sweaty even in cool environments.
For years, the assumption has been that your metabolism is slowing as you age. But a study that included 6,500 people from 29 countries shows that metabolism for both men and women really doesn't significantly drop off until you reach the age of 60.
A Fast Metabolism
This rate changes from person to person based on a number of factors, including genetics, diet, and level of activity; if you eat a lot but don't gain weight, it could be because your BMR is high, so you burn calories at a greater rate than most people.
If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
The benefits of increasing your metabolism will provide you with more energy, aid in weight loss and keep it off, and help you experience quality sleep while burning more calories at bedtime.
Some people claim to have been born with a “fast metabolism.” There is a genetic component to metabolism, but your lifestyle and health habits have a bigger impact on your metabolism than you may think. The most significant factor that affects your metabolism rate is muscle mass.
Calculate Basal Metabolic Rate
Your basal metabolism rate is produced through the following basal metablic rate formula: Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
MYTH! You can't measure the speed of your metabolism by your puddles of perspiration. There are a number of reasons why you may have to towel off after a workout: It's hot in the gym, your gym clothes don't wick sweat, or you bundled up when it wasn't that chilly outside.
Summary. The hormones leptin, insulin, oestrogens, androgens and growth hormone influence our appetite, metabolism and body fat distribution.
Researchers found that metabolism peaks around age 1, when babies burn calories 50 percent faster than adults, and then gradually declines roughly 3 percent a year until around age 20.
It may be that you have a fast metabolism (meaning your body burns energy from food at a fast rate than the people around you) or you're just naturally slender. For some people, underlying health conditions and certain medications and treatments can make it difficult to reach and/or maintain a healthy weight.
Amount of physical activity – hard-working muscles need plenty of energy to burn. Regular exercise increases muscle mass and teaches the body to burn kilojoules at a faster rate, even when at rest. Drugs – like caffeine or nicotine, can increase the BMR.
