Study Identifies Brain Circuits That Cause Fatty Food Craving

Do you feel the urge to binge on golden hot chips, cheesy pizza, crispy chicken, heartwarming hamburgers, all when on a diet? Researchers have identified new brain circuits that may act as a brake on binge eating and junk food craving.

In the study, led by a team from the University of Texas at Galveston on rats who had spent a month eating a low-fat diet, the team successfully inhibited the fatty food seeking behaviours.

“Craving for foods high in fat — this includes many junk foods — is an important part of obesity and binge eating,” said Jonathan Hommel, Assistant Professor at the University of Texas in the US.

Cholesterol -- a molecule normally linked with cardiovascular diseases -- may also play an important role in the onset and progression of Alzheimer's disease, researchers have found.

“When trying to lose weight people often strive to avoid fatty foods, which ironically increases motivation and craving for these foods and can lead to overeating. Even worse, the longer someone abstains from fatty foods, the greater the cravings,” Hommel added.

Several behavioural studies have demonstrated that denying certain foods while on a diet causes increased craving and motivation for that food.

However, the brain mechanisms that lead to this type of overeating are not known.

For the study, published in the journal Behavioural Brain Research, half of the rats underwent a surgical procedure that blocked the effects of a brain chemical called neuromedin U receptor 2 within a region of the brain that regulates food intake.

The other half of the rats did not receive this treatment.

After surgical recovery, the rats who had been treated did not work nearly as hard for fatty treats as their unaltered counterparts did.

“While our findings are only the first step in a long process from the scientific lab to the doctor’s office, we are planning to develop new drugs to help curb those cravings,” Hommel said. (IANS)

The unhealthy habits of modern-day living with a diet high in calories may cause brain health to deteriorate faster, according to an Australian study published on Thursday.

Compared to 50 years ago, people currently consume an average of around 650 extra kilocalories each day, which is equivalent to a fast-food meal of a burger, fries and a soft drink, said the study’s lead author, Nicolas Cherbuin of the Australian National University (ANU).

“People are eating away at their brain with a really bad fast-food diet and little-to-no exercise,” Cherbuin, who is a professor at the ANU Centre for Research on Ageing, Health and Wellbeing, said in a statement.

“We’ve found strong evidence that people’s unhealthy eating habits and lack of exercise for sustained periods of time puts them at serious risk of developing type 2 diabetes and significant declines in brain function, such as dementia and brain shrinkage,” he added.

According to the study, 30 per cent of the global adult population is either overweight or obese, and over 10 per cent of the world’s adult population will have type 2 diabetes by 2030, reports Efe news.

The expert pointed out that while the link between this type of diabetes and the deterioration of brain function has long been known, research shows that the loss of neurons and their functions begins “much, much earlier”, indicating “a clear association between this brain deterioration and unhealthy lifestyle choices”.

“People eating too much of the wrong kind of food, particularly fast food, is the other big worry,” according to the expert, who warned that advice for people to reduce their risk of brain problems, including their risk of dementia, begin too late, mostly when people are in their 60s or later.

“The damage done is pretty much irreversible once a person reaches midlife, so we urge everyone to eat healthy and get in shape as early as possible – preferably in childhood but certainly by early adulthood,” Cherbuin said. (IANS)
