Metabolism doesn’t slow down until age 60, according to main research

  • New research shows that middle-aged people have the same calorie-burning potential as people in their 20s.
  • The results show that although your metabolism slows down from infancy to adolescence, it remains stable from 20 to 60.
  • One expert said this “key” study questions everything we know about weight control.

Popular wisdom says that you cannot continue to eat like 20-something in your 30, 40 or more years – you will start gaining weight, because, as we were told, our body burns calories more slowly with age. …

This may not be the case, according to a study published in the journal Aug 12. The science, which showed that from the age of 20, your metabolism practically does not change until the age of 60.

More than 80 researchers from different laboratories have pooled their resources to study data from 6,421 people over 40 years to see how factors such as age, size, and gender affect metabolism. The researchers used a technique called the “double-labeled water test” to measure the level of carbon dioxide a person produces to estimate their energy expenditure.

They found that while age does play a role in how quickly we burn calories, it doesn’t slow down our metabolism as much or as quickly as previously thought.

Leanne Redman, an energy balance physiologist at the Pennington Biomedical Research Institute who is not involved in the research, said: The newspaper “New York Times that the results are “key”.

“It will be in the textbooks,” Redman said.

Research has shown that middle age, pregnancy, and even menopause have little effect on metabolism.

The study analyzed human metabolism at four stages of life – from infancy to one year; from one to 20; 20 to 60; 60 and older – and babies have been found to burn the most calories, in proportion to their size.

From then on, they found, metabolism began to slow down steadily until age 20, with a slight decline of about 2.8% each year.

The researchers found that after 20 years, the metabolism remains stable for the next four decades, finally to 60 years.

The researchers said it was surprising to find that factors such as middle age, pregnancy, or even menopause didn’t seem to affect the ability to burn calories.

“We have not found any evidence to support this. So if you gain weight [on] and your waistline expands by the age of 30-40, probably because you eat more food and then use less energy, ”says John Speakman, study co-author and professor at the University of Aberdeen. said the Guardian

The findings could be critical to helping scientists better understand important questions about metabolic health, including how to fight disease, prescribe medication correctly, and how to help people live longer, healthier lives at all stages of life.
