"Oh, my metabolic capacity declines as soon as I turn 30, unlike when I was 20, I didn't get fat even when I was eating
"Oh, my metabolic capacity declines as soon as I turn 30, unlike when I was 20, I didn't get fat even when I was eating
Everyone should have heard this sentence
But does the metabolic capacity really decline after the age of 30?
A recent study published in Science showed that our metabolism does not really start to decline until after the age of 60

DOI: 10.
In the study, the researchers used a large, diverse database.
The researchers used the "doubly labeled water" method to calculate the participants' total daily energy expenditure.
The results of the study are surprising.
The researcher divided his life into four different life stages based on metabolic ability
The second stage is adolescents from 1 to 20 years old,
The third stage is adulthood (20 to 60 years old),
The fourth stage is after 60 years of age
The first stage is for newborns under 1 year old,

In the first stage (0-1 years old), the energy expenditure of newborns in the first month after birth is similar to that of adults.
In the first stage (0-1 years old), the energy expenditure of newborns in the first month after birth is similar to that of adults, with adjusted total energy expenditure (TEE) and basalexpenditure ( BEE) of 99.
The infant’s high metabolic capacity is understandable.
If the infant does not get enough food, it is unlikely to survive or grow up healthily
.
In the second stage of adolescence (1-20 years old), after the initial metabolic capacity surge in infancy, metabolism declines by about 3% every year until the 20s
.
The data showed that total energy expenditure decreased from 147.
8±22.
6% for 1 to 2 years old to 102.
7±18.
1% for 20 to 25 years old, and then stabilized at the adult level (20-60 years old)

Although adolescence is the peak period of growth, people would think that total energy expenditure will be high at this stage, but the researchers did not see any increase in daily calorie requirements during adolescence after taking into account the body size

"We really thought that puberty would be different, but it is not the case," the study author said

In the third stage of middle age (20-60 years old), the results of the study are again surprising
.
Many of us think that our metabolic capacity will decline year by year after the age of 30, but researchers have found that between the ages of 20 and 60, our energy expenditure is the most stable.
Even during pregnancy, women’s calorie needs are not comparable.
Expected more or less

In the fourth stage, after the age of 60, the metabolism begins to decline year by year, dropping by 0.
7% every year
.
A person in his 90s needs 26% fewer calories a day than a middle-aged person

Looking at these results, are you still blaming your middle-aged fates for the decline in metabolic capacity? Perhaps the biggest reason for middle-aged happiness is to eat more and exercise less
