Prolonged periods of sedentary time strongly associated with amount of fat around internal organs

A team of researchers has found new evidence to suggest that longer periods of sedentary time (defined as any sitting/reclining activity with low energy expenditure) are more strongly associated with the amount of fat deposited around internal organs, according to Science Daily.

The study, Obesity took 124 participants at high risk of type 2 diabetes and measured the length of time they spent sedentary over a period of 7 days using accelerometers fitted to their waist. The research team also scanned the participants using magnetic resonance imaging (MRI) equipment to accurately measure the amount of fat in the liver, inner (visceral) and outer (subcutaneous) fat layers, and total abdominal fat.

Even when accounting for age, and physical activity levels, the study team found that the longer a person remained sedentary during the day, the higher the levels of liver fat, inner (visceral) fat and total abdominal fat.

Virus could treat brain cancer and boost immune system

Patients with aggressive brain tumours could be treated with a virus, according to a new study. Injected directly into the bloodstream, the virus could also boost their immune system in the process.

Scientists at the University of Leeds and the Institute of Cancer Research in London carried out successful trials on nine brain cancer patients using a ‘reovirus’. The researchers found the virus could cross the protective membrane surrounding the brain to reach tumours, according to RT.

You DO burn more calories in the cold

You really can shiver off the calories this winter, according to personal trainers and  exercise physiologists, according to Daily Mail. 

The body's primary goal is to maintain stasis, or stability, and that includes keeping a steady temperature. 

So, in the cold, the body needs to burn extra fat, to produce energy to heat it back up to the ideal temperature. 

But there's a trick to it, and personal trainer Max Zeumer spoke about his surprisingly fun tips for how to optimize your cold weather workout.

Heart attack care dangerously unequal for women

Fewer women who suffer a heart attack would die if they were given the same treatments as men, a new study found.

Researchers analysed the outcomes of 180,368 Swedish patients who suffered a heart attack over a 10-year period, according to BBC.

They found women were three times more likely to die from their heart attack than men in the year after having one.

The British Heart Foundation said: "Heart attacks are often seen as a male health issue, but more women die from heart disease than breast cancer."

Could sugar be responsible for the obesity and diabetes epidemics?

The idea that sugar could be a fundamental cause of the global obesity and diabetes epidemics, with deleterious effects on the human body that go beyond just empty calories, should be considered seriously again, according to Science Daily.

In the midst of such a huge public health crisis, Taubes says "we must do more to discourage consumption while we improve our understanding of sugar's role.

Doctors have long suspected sugar is not simply a source of excess calories but a fundamental cause of obesity and type 2 diabetes, writes Taubes. But until recently, fat consumption and total energy balance have dominated the debate about obesity and the nature of a healthy diet.
