Metabolism in adulthood does not slow as commonly believed, study finds. Metabolic rate remains stable all through adult life, from age 20 to 60 years old.
Your metabolic rate peaks in your early 20s, according to Women's Health Magazine. At this age, you tend to have a higher muscle mass and have a fair amount of physical activity built into your day. As early as age 30, however, men and women begin noticing a dip in their ability to lose weight.
Your metabolic rate does change during your early life, but it plateaus between the ages of 20 and 60, and only decreases by around 1% per year after that. Your total daily energy expenditure also depends on your weight.
Teenagers may be said to eat their parents out of house and home, but research suggests their daily energy expenditure isn't much greater than that of adults.
As we age, our metabolism slows and the rate at which we break down food decreases by 10 percent each decade after age 20. Metabolism is the amount of energy (calories) your body uses to maintain itself.
"The biggest thing people do that slows their metabolism down is eating too few calories," said Fiore. 1200 calories per day is roughly the amount you need to perform basic functions, she suggested, and when a person eats fewer than that, the metabolism slows down to conserve energy.
A new study suggests that children's metabolism temporarily slows during puberty, a pattern that might help explain the current teen obesity problem. The study found that kids' resting energy expenditure typically dropped during puberty. That refers to the number of calories the body burns at rest.
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.
Weight loss can benefit people of all ages — even teens. Losing excess body fat can improve health and boost self-esteem and confidence. However, it's important for teens to lose weight the healthy way by making diet and lifestyle changes that nourish growing bodies and can be followed long term.
As metabolic rate increases the lifespan of an organism is expected to decrease as well.
Metabolism is partly genetic and largely outside of one's control. Changing it is a matter of considerable debate. Some people are just lucky. They inherited genes that promote a faster metabolism and can eat more than others without gaining weight.
If your metabolic age is lower than your actual age, it means your body is in good health. Some adults can have the metabolic age of a 15-year-old or lower, which means their body is top of the class at burning calories.
However, some teens may suffer from a slower metabolism and can gain an unhealthy amount of weight. Fortunately, lifestyle changes such as exercising regularly, getting enough sleep, and eating a balanced diet can help teens speed up their metabolism.
Signs of a fast metabolism include increased calorie burning, difficulty gaining weight, increased breathing, insomnia and frequent sweating. The term fast or slow metabolism is often used depending on the speed of a person's basal metabolic rate (BMR).
As you go through puberty, you'll get taller, your shoulders will get broader, and as your muscles get bigger, your weight will increase. Sometimes the weight gain of puberty causes girls and boys to feel so uncomfortable with how they look that they try to lose weight by throwing up, not eating, or taking medicines.
Many guys and girls are skinny until they start to go through puberty. The changes that come with puberty include weight gain and, in guys, broader shoulders and increased muscle mass.
Metabolism drops starting at age 10
The research found that 15-year-olds burn 400 to 500 fewer calories while at rest per day compared to when they were 10-years-old – a drop of 25 per cent. But by the age of 16, their calorie expenditure begins to climb again.
Luckily, a slow metabolism isn't permanent, and with the right changes to your diet and lifestyle, you can rev up your metabolism — and get back to feeling better in the process.
