More people concentrate on maintaining healthy and in shape as they grow older, but it is true that it can be more difficult with age.
New research has revealed that cell changes during the aging process can cause belly fat, and this is aggravated by stressful problems and are contributing to weight gain.
“People often lose their muscle and gain body fats as they grow older, even when their body weight remains the same,” said the author of the Qiong (Annabel) Wang, doctor, assistant professor of the Molecular and Cellular Endocrinology Department of the City of Hope, in a statement.

Published in Science Magazine, preclinical research involved experiments on mice that were later confirmed by human cells.

The researchers focused on a group of stem cells called adipocyte progenitor cells (APCS) within the fatty tissue responsible for age -related weight.
When they transplanted these cells from mice of various ages in another group of younger mice, they noticed the creation of large number of fat cells inside the younger mice.

However, when they transplanted a batch of young mice cells into old mice, they did not see the same effect.
The results confirmed that the older stem cells are more likely to drive to new fat cells, regardless of the age of the host who received them, said the press release.

“While most adult stem cells of stem cells grow wans with age, the opposite is true of APCS: aging unlocked the power of these cells to evolve and extend,” said Adolfo Garcia-Ona, president of the Department of Molecular and Cellular Endocrinology of the City of Hope, in a press release.
Aging also changes these APCs in another group of cells called engaged pre-adypocytes, specific to age (CP-AS), which actively take new fat cells.

Humans have a “signaling route”, a chemical reaction that controls the way the body makes cells, called the receptor of the leukemia inhibitory factor (LIFR), according to experts.
“Our research indicates that LIFR plays a crucial role in triggering the CP-AS to create new fat cells and expand the belly fat in older mice,” Wang said in the same launch.
3 ways to prevent belly fat
Despite the effects of aging, there are measures that people can take to prevent the waists from expanding, according to Dr. Sajad Zalzala, co -founder and medical director of Agelessrx in Detroit, Michigan.
“As we grow old, our ability to maintain lean muscle mass decreases, which contributes to metabolic slowdown and increased fat storage, especially around the abdomen.” (Istock)
1. Prioritize the protein
“As we grow old, our ability to maintain lean muscle mass decreases, which contributes to metabolic slowdown and increased fat storage, especially around the abdomen,” said Zalzala, who was not involved in Hope’s city study, told Fox News Digital.
He recommends starting the day with 20 to 30 grams of protein, which can be found in foods such as Greek yogurt, protein smoothies and eggs.

Eating protein at the beginning of the day keeps you full time, stabilizes blood sugar and promotes muscle maintenance, according to the doctor.
2. Optimize sleep and stress management
“High chronic cortisol levels, which can be driven by poor sleep or stress, promote fat storage, especially at the waist,” said Zalzala.
An expert recommends stress reduction strategies such as walking, awareness and breathing to reduce cortisol levels. (Istock)
According to experts, people should sign up for seven to nine hours of sleep per night.

Zalzala also recommends stress reduction strategies such as walking, awareness and breathing, calling them “powerful tools for fat regulation and metabolic health.”
3. Limit ultra -processed carbohydrates and refined sugars
“The study reminds us that adipose tissue aging behaves differently: it is more inflammatory and prone to dysfunction,” Zalzala said.

“Minimizing added sugars and highly processed carbohydrates (white bread, pastry, sugary drinks) reduces insulin resistance and fat accumulation, especially visceral fat at the bottom of the belly.”
