On the contrary, people who live more than a half mile away from any food outlets are more likely to be fatter.

“Having access to a range of food options in your neighbourhood affects both your energy input and output,” said Cathleen Zick, University of Utah.
“A healthy grocery option may influence the food you choose to buy, while having multiple food destinations within walking distance might encourage you to walk, rather than drive, to your next meal,” she added.

The study suggests that placing restrictions on fast food outlets may not be effective, but that initiatives to increase healthy neighbourhood food options may reduce individuals' obesity risks, especially if focused on low-income neighbourhoods.
Earlier, Zick and colleagues found that residents were at less risk of being obese or overweight if they lived in walkable neighbourhoods.

Healthy lifestyle, drug for diabetes
Rigorous lifestyle changes aimed at modest weight loss and oral drug metformin can reduce the risk of developing Type 2 diabetes, a new study has found.
Boffins at Washington University determined the results from the Diabetes Prevention Programme Outcomes Study (DPPOS), a 10-year follow-up study of patients who participated in the Diabetes Prevention Programme.
The DPPOS found that patients at high risk for developing Type 2 diabetes who made lifestyle changes also had lower blood pressure and triglyceride levels.
The study also found that those treated with the oral diabetes drug metformin, rather than intensive lifestyle changes, reduced the rate of developing diabetes by 18 per cent after 10 years compared with a placebo.

Risks of driving after angioplasty
A new study, conducted by Indian-origin boffin, has shown that more than half of patients with acute coronary syndrome (ACS) don’t get any counselling on their ability to drive after angioplasty — and this could be putting their lives at risk.
Dr Ravi Bajaj said after a patient is sent home from hospital following a ‘cardiac event’, such as angina or chest pain from reduced blood flow to the heart, there is always the risk they could have another serious cardiac event.
“That is why patients are advised not to operate a motor vehicle during the time when risks of an event are high,” Dr Bajaj said.
In his study, Dr Bajaj looked at patients who had undergone angioplasty, which is a non-surgical procedure that uses a tiny balloon to open up clogged blood vessels in the heart that have been narrowed by cholesterol and plaque build-up.

Depression and level of perception
People who are depressed tend to recall more physical symptoms such as aches and pains than they actually experience, say researchers.
The study from University of Iowa College of Liberal Arts and Sciences indicates that depression and not neuroticism is the cause of such over-reporting. Depressed people tend to ruminate over and exaggerate the bad.
“People who felt depressed made the most errors when asked to remember their physical symptoms,” said lead researcher and psychologist Jerry Suls.
