A new diet, inspired by Ramadan, suggests that eating carbohydrates in the evening increases feeling of fullness.

A study has found tucking into a bowl of pasta at night can actually reduce the risk of diabetes and heart disease.

A team from the Hebrew University carried out the research after studying the diets of Muslims during Ramadan, when people fast during the day and eat carb-heavy evening meals.

Complex carbohydrates are a good source of energy and include wholegrain pastas, breads and rice as well as beans.

They found the diet increased satiety – the feeling of being full – and influenced the production of hormones associated with heart attack risk factors.

This made it a promising eating regime for overweight people trying to slim down.

Professor Zecharia Madar, chief scientist at Israel’s Ministry of Education, explained: “The idea came about from studies on Muslims during Ramadan, when they fast during the day and eat high-carbohydrate meals in the evening, that showed the secretion curve of leptin was changed.”

He led a team that assigned 78 police officers to either the Ramadan diet (carbohydrates at dinner) or a control weight loss diet (carbohydrates throughout the day).

After six months researchers examined the experimental diet’s effect on the secretion of three hormones: leptin, the satiety hormone; ghrelin, the hunger hormone; and adiponectin, the link between obesity, insulin resistance and the metabolic syndrome.

The researchers found that the experimental diet led to positive changes in the hormonal profiles of the Ramadan dieters.

The diet led to lower hunger scores, as well as better weight, abdominal circumference and body fat outcomes compared to the control group.
The experimental dieters also recorded improvements in their blood sugar, blood lipids and inflammatory levels.

The findings suggest there is an advantage in concentrating carbohydrate intake in the evening, especially for people at risk of developing diabetes or cardiovascular disease due to obesity.

“The findings lay the basis for a more appropriate dietary alternative for those people who have difficulty persisting in diets over time,” said Prof. Zecharia Madar.

“The next step is to understand the mechanisms that led to the results obtained.”

The study was published in the Obesity and Nutrition, Metabolism and Cardiovascular Diseases journals.

A new research claims the logos of companies like McDonalds, Pizza Hut and Burger King are “branded” on the youngsters’ brains.

MRI scans of children’s appetite and pleasure centres reveals they light up when they are shown advertising images of their favorite fast foods, according to scientists.

But when the logos were well-known brands but had nothing to do with food the same areas of the brain failed to respond.

They appear to have tapped into the “reward” areas of the brain which develop before youngsters learn self-control.

A new research claims the logos of companies like McDonalds, Pizza Hut and Burger King are “branded” on the youngsters' brains

Researcher at the University of Missouri-Kansas City and the University of Kansas Medical Center, divided 120 popular food and non-food brands, including McDonald’s and Rice Krispies, and BMW and FedEx, reported the Sunday Independent.

They used a magnetic resonance imaging scanner which monitored changes in the blood flow that increases when the brain becomes more active.

Analysis of the tests on children, aged 10 to 14, showed there was increased activity in parts of the brain in the “reward” centres and in driving and controlling appetite.

Study leader Dr. Amanda Bruce told the Independent: “Research has shown children are more likely to choose those foods with familiar logos.

“That is concerning because the majority of foods marketed to children are unhealthy.”

Last year, children aged six to 13, took part in research into the effect of exposure to TV ads for unhealthy food products.

The children were shown 10 advertisements for junk food and then asked to choose between three food options which were described as “high fat, high carbohydrate”, “high protein”, and “low energy”.

Options for high protein included items like roast chicken. The low energy ones included items like salad.

The children were then shown a series of ten advertisements for toys and presented with a similar questionnaire.

Results of the study suggest that children exposed to unhealthy food ads – as opposed to toy ads – are far more likely to show unhealthy eating preferences.

These effects were especially pronounced among study subjects who typically watched more than 21 hours of TV per week.
