Scientists may have discovered why the pounds come back after losing weight

Many factors pb to the frustrating rhythm of value summation and value nonaccomplishment — but the driving unit whitethorn beryllium abdominous cells keeping a memory of obesity.

That’s according to a caller survey that was archetypal published successful the diary Nature past fall.

Researchers accidental that abdominous cells power abnormal metabolic pathways successful the assemblage agelong aft pounds are shed, which could marque it much apt for radical to regain weight.

STUDY DIRECTLY COMPARES ZEPBOUND AND WEGOVY FOR WEIGHT-LOSS RESULTS

Study findings

The squad of Swiss scientists were funny whether regaining weight aft slimming down is owed to "metabolic memory," wherever the assemblage remembers and strives to instrumentality to its erstwhile authorities of obesity.

They analyzed chemic markers connected abdominous cells successful mice who were fed a high-fat diet. Next, erstwhile the mice were fed lone a modular meal, the researchers analyzed their fatty insubstantial aft they had mislaid weight, according to the survey write-up.

The squad past compared these samples to a thin mice radical that was fed a standard meal to spot if the chemic markers connected the abdominous cells were associated with unhealthy changes successful the body.

The mice connected the high-fat fare continued to person unhealthy changes successful their metabolism aft losing weight, including much trouble successful regulating sweetener metabolism, much inflammation and abnormal abdominous storage.

Mice who were antecedently obese gained value faster compared to the power radical aft they ate a high-fat fare — suggesting a continued impairment successful metabolism aft losing weight, the researchers found.

The survey besides looked astatine quality samples, analyzing however the genes successful abdominous cells tin pb to unhealthy changes successful the assemblage arsenic they did successful mice. 

The researchers analyzed the fatty tissues of participants earlier and aft they underwent bariatric surgery, comparing them to the fatty cells of thin individuals who did not person a past of obesity.

"This caller probe suggests that aft idiosyncratic loses weight, their abdominous cells don’t afloat spell backmost to ‘normal.’"

In obese individuals, the genes from abdominous cells continued to relation abnormally successful the body, starring to much inflammation and metabolic problems 2 years aft losing weight.

One regulation of the study is that it lone looked astatine 1 benignant of compartment – abdominous cells. More research is needed to determine whether different cells oregon tissues successful the assemblage besides support a representation of being overweight, the researchers acknowledged.

‘Complex mix’ of factors

Fat cells so person a representation of being obese, which tin marque it easier to regain value and enactment successful a authorities that promotes inflammation and metabolic issues, confirmed Gretchen Zimmermann, registered dietitian and vice president of objective strategy at Vida Health, a virtual obesity attraction provider. (She was not portion of the study.)

"This caller probe suggests that aft idiosyncratic loses weight, their abdominous cells don’t afloat spell backmost to 'normal,’" Zimmermann told Fox News Digital.

But portion biology plays a captious relation successful obesity, it’s not everything, she cautioned.

"A analyzable premix of genetics, biology, environment, psychology, medications and societal determinants each signifier obesity," Zimmermann said.

"Keep moving, eating existent nutrient and gathering muscle."

Healthy habits tin counteract the genetics that beforehand value gain.

Ideally, the adept said, this entails getting a operation of physical activity (including spot training), a capable magnitude of macromolecule and fiber, and phytonutrients from plants that antagonistic oxidative accent and chronic inflammation, according to Zimmermann.

"Keep moving, eating existent nutrient and gathering muscle," she said.

"These behaviors trim inflammation, amended humor sweetener control, lend to a steadfast microbiome and support metabolism — adjacent if value doesn’t driblet overmuch oregon stays the same."

For some, however, the underlying contented whitethorn lie successful epigenetics, which involves however a person’s behaviors and surrounding situation power however genes enactment successful the body, according to the Centers for Disease Control and Prevention.

"Obesity is simply a chronic relapsing information that has an epigenetic cause," Dr. Caroline Apovian, prof of medicine astatine Harvard Medical School and co-director of the Center for Weight Management and Wellness astatine Brigham and Women's Hospital, told Fox News Digital.

People who are much prone to storing calories whitethorn person a harder clip losing value and keeping it disconnected done diet and exercise, compared to those who whitethorn person an easier time, according to Apovian, who was not progressive successful the study.
