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)

As you scramble to buy some onions for your family despite skyrocketing prices, a rising Body Mass Index (BMI) and an increasing body height is leading to a marked increase in global calorie requirements globally, find researchers.

In most countries, average body height and body size is increasing and more needs to be eaten to maintain the higher weight.

Even if both BMI and height were to remain constant, global calorie requirements would still increase by more than 60 per cent by 2100 because of population growth, said the team from the University of Gottingen in Germany in a paper published in the journal PLOS ONE.

The development economist Professor Stephan Klasen and his then doctoral Lutz Depenbusch have designed a scenario to investigate how calorie intake could develop between 2010 and 2100.

Earlier changes in the Netherlands and Mexico were used as a benchmark.

“The developments in these countries are very pronounced,” says Depenbusch, “but they do represent a realistic scenario.”

With rising BMI, as observed in Mexico, and increasing height, as seen in the Netherlands, there would be a further increase in calorie intake by more than 18 per cent.

This means, the increase in global calorie requirements between 2010 and 2100 would be one third larger, reaching a total increase of nearly 80 per cent, said the researchers.

If global food production does not meet this increased need, this problem will not be controlled by a corresponding decrease in BMI.

While richer people will be able to maintain their eating habits, the poor would suffer greatly from higher prices due to increased demand.

“This would lead to increased consumption of cheap food, often rich in calories but poor in nutrients,” said Depenbusch.

“As a result, body weight among the poor would continue to rise alongside malnutrition and poorer health outcomes.” (IANS)
