ISLAMABAD  - The results of a recent study indicate that those who lead lazy lifestyles face the same risk of death as smokers and the obese.

According to the study, physical inactivity in 2008 led to the death of nearly 5.3 million people across the world, that is one in every 10 deaths, Press TV reported.

This comes while smoking is responsible for about 5 million deaths throughout the world every year.

“Physical inactivity has a large impact on the health of the world. In fact, its impact is comparable to that of cigarette smoking,” said Dr.

I-Min Lee, a professor of medicine at Harvard Medical School and lead author of the study.

The study also found that lack of exercise ups the risk of serious diseases including type 2 diabetes, colon cancer, breast cancer, and coronary heart disease.

Researchers suggested that doing at least 150 minutes of moderate physical activity, such as quickly walking, cycling or gardening for 30 minutes each week help adults to stay healthy.

They further said that governments must warn people of the hazards of not getting enough exercise and make doing physical activity more convenient for citizens.

Meanwhile, the Lancet research showed that people in richer countries do the least amount of exercise.

Exercise on daily basis can improve memory

A new study has suggested that doing exercise for up to an hour a day can improve memory and learning in children and the elderly.

According to research, walking or cycling regularly for between six months to a year can improve memory and problem solving skills in the elderly by between 15 and 20 per cent, Press tv reported.

They have shown that such exercise can also increase the size of crucial parts of the brain. The scientists have also discovered that children who are fit also tend to be better at multitasking and performing difficult mental tasks than unfit friends.

“It is aerobic exercise that is important, so by starting off doing just 15 minutes a day and working up to 45 minutes to an hour of continuous working, we can see some real improvements in cognition after six months to a year.”

Study ties skipping breakfast to weight gain

Brain scans indicate that skipping breakfast lead the brain to respond more positively to unhealthy diet and seek out higher-calorie foods, new study says.

According to the study, conducted at Imperial College London, people who miss breakfast not only intend to eat more for lunch but they usually consume fatty and sugary foods that put them in a high risk of gaining weight, Press TV reported.

To understand what happened inside the brain, the researchers took 21 people, who were all normal weight, under their study tests.

The MRI brain scans showed a region known as orbital frontal cortex, responsible for identifying the food taste particularly when breakfast had been skipped.

On one day they were given no breakfast before the scans and on a different day they were fed a large, 730 calorie, breakfast an hour and a half before.

The researchers demonstrate that skipping breakfast created a “bias” in the brain in favour of high calorie foods.

“Through both the participants’ MRI results and observations of how much they ate at lunch, we found ample evidence that fasting made people hungrier, and increased the appeal of high calorie foods and the amount people ate,” said Dr. Tony Goldstone, from Imperial College London.

Presented at the Neuroscience 2012 conference, the result revealed that when breakfast was missed the brain’s “food appeal” was high calorie foods but not low calorie as “the orbitofrontal cortex, became more active on an empty stomach.”
