Overweight and obesity are defined by the WHO as abnormal or excessive fat accumulation that presents a risk to an individuals health.

Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer and while it was once an issue only in high income countries, overweight and obesity has now dramatically risen in low- and middle-income countries.Such countries are now facing a "double burden" of disease, for while they continue to deal with the problems of infectious disease and under-nutrition, they are also experiencing a rapid upsurge in chronic disease risk factors such as obesity and overweight, particularly in urban settings.
Appropriate traffic signs could help improve road safety for bicyclists and motorists

Appropriate traffic signs could help improve road safety for bicyclists and motorists

A simple change in the wording of a traffic sign - from "Share the Road" to "Bicycles May Use Full Lane" - could help clarify the rules of the road for bicyclists and motorists, according to a North Carolina State University study. [More]
Study shows lack of folic acid enrichment in Europe causes foaetal abnormalities

Study shows lack of folic acid enrichment in Europe causes foaetal abnormalities

A new international study shows that 5,000 foetuses in Europe annually are affected by spina bifida and other severe defects on the central nervous system. Seventy per cent of these pregnancies are terminated, while increased mortality and serious diseases affect the children who are born. At least half of the cases can be avoided by adding folic acid to staple foods as is already being done in seventy non-European countries. [More]
Fish oil diet modifies gut bacteria to boost health

Fish oil diet modifies gut bacteria to boost health

Diets rich in fish oil versus diets rich in lard produce very different bacteria in the guts of mice, reports a study from Sahlgrenska Academy published in Cell Metabolism. The researchers transferred these microbes into other mice to see how they affected health. The results suggest that gut bacteria share some of the responsibility for the beneficial effects of fish oil and the harmful effects of lard. [More]
Researchers find fatty acid deposits in brains of Alzheimer's patients

Researchers find fatty acid deposits in brains of Alzheimer's patients

People with Alzheimer's disease have fat deposits in the brain. For the first time since the disease was described 109 years ago, researchers affiliated with the University of Montreal Hospital Research Centre (CRCHUM) have discovered accumulations of fat droplets in the brain of patients who died from the disease and have identified the nature of the fat.

Researchers identify new virus that plays role in rare type of liver cancer

More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus. [More]
Obesity raises Lynch syndrome CRC risk

Obesity raises Lynch syndrome CRC risk

Obesity increases the risk of colorectal cancer in patients with Lynch syndrome, research indicates, but daily aspirin use may combat this excess risk. [More]
Pre-birth arsenic exposure associated with early puberty, obesity in mice

Pre-birth arsenic exposure associated with early puberty, obesity in mice

Female mice exposed in utero, or in the womb, to low levels of arsenic through drinking water displayed signs of early puberty and became obese as adults, according to scientists from the National Institutes of Health. [More]
Cornell study reveals how obesity changes consistency of breast tissue

Cornell study reveals how obesity changes consistency of breast tissue

Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published this month in Science Translational Medicine explains how obesity changes the consistency of breast tissue in ways that are similar to tumors, thereby promoting disease.

Physical inactivity poses important clinical, public health and fiscal challenges for the U.S.

Physical inactivity poses important clinical, public health and fiscal challenges for the U.S.

What do a prominent physiologist and two-time survivor of pancreatic cancer and a world-renowned researcher whose landmark discoveries on aspirin, drug therapies of proven benefit and therapeutic lifestyle changes that have saved more than 1.1 million lives have in common? They are both passionate about the importance of regular physical activity in reducing risks of dying from heart attacks and strokes, as well as developing diabetes, hypertension and colon cancer. And more importantly, enhancing mental health and fostering healthy muscles, bones and joints in all Americans from childhood to the elderly. [More]
New Pitt analysis reveals causes of stillbirth among obese women

New Pitt analysis reveals causes of stillbirth among obese women

Obese women are nearly twice as likely as their lean counterparts to have stillborn babies for several specific, potentially preventable medical reasons, a new University of Pittsburgh Graduate School of Public Health analysis reveals. [More]
Drinking 500ml of water before meals may help obese adults to lose weight

Drinking 500ml of water before meals may help obese adults to lose weight

Researchers from the University of Birmingham have shown that drinking 500ml of water at half an hour before eating main meals may help obese adults to lose weight. They believe that the simple intervention could be hugely beneficial, and be easily promoted by healthcare professionals and through public health campaigns. [More]

High dietary iron intake suppresses hormone that regulates appetite

High dietary iron intake suppresses hormone that regulates appetite

Here's one more reason to cut down on the amount of red meat you eat. Using an animal model, researchers at Wake Forest Baptist Medical Center have found that dietary iron intake, equivalent to heavy red meat consumption, suppresses leptin, a hormone that regulates appetite. [More]
Researchers examine relationship between energy needs and 'pleasure' of eating in food intake

Researchers examine relationship between energy needs and 'pleasure' of eating in food intake

A team at the Laboratoire biologie fonctionnelle et adaptative (CNRS/Université Paris Diderot) investigated the relative role of energy needs and "pleasure" of eating in food intake. The researchers studied a group of neurons in mice. They observed that when the neuron activity is compromised, feeding behavior becomes less related to the body's metabolic needs and more dependent on food palatability. [More]
Variation in genetic mechanism increases fat storage and drives obesity

Variation in genetic mechanism increases fat storage and drives obesity

A specific gene region has long been suspected of contributing to obesity in humans but the precise mechanisms behind this were previously unclear. Now, researchers at the Technical University of Munich (TUM), Massachusetts Institute of Technology (MIT), Harvard Medical School and other partners have been able to show that a single genetic alteration in this region reduces thermogenesis (fat burning), instead increasing lipid storage.
