Obesity epidemic could be caused by childhood sugar intake

Current obesity rates in adults in the US could be the result of dietary changes that took place decades ago, according to a study published by researchers at the University of Tennessee, Knoxville. If high-sugar diets in childhood have long-lasting effects, the changes we see now in adult obesity rates may have started with diets decades ago, when those adults were children.

Anti-starvation mechanism may drive obesity epidemic

A study by researchers from the NYU School of Medicine have revealed that anti-starvation mechanism that kept our ancient ancestors from starving may now be contributing to the obesity epidemic. In starvation times, researchers state that animals were more likely to survive if they could hoard and stretch out their stored energy. Even if an animal secured a rare feast, evolution smiled on the storage of excess fuel as fat, given the likelihood of a quick return to starvation.

Oversized meals are a factor in obesity epidemic

A study conducted in Brazil, China, Finland, Ghana, India and the US found 94 percent of meals served in restaurants contain more than the recommended number of calories according to the UK's National Health Service. Restaurants frequently serve oversized meals, not only in the US but also in many other countries, according to a study conducted by an international team of researchers and supported by FAPESP - São Paulo Research Foundation.

Animal study reveals ankyrin-B gene fuelling the obesity epidemic

Research from the Research Triangle suggests that variants in a gene called ankyrin-B could cause people to put on pounds through no fault of their own. The study, which was conducted in mice, shows that the gene variation causes fat cells to suck up glucose faster than normal, more than doubling their size. When an aging metabolism or high-fat diet is added to the equation, obesity becomes all but inevitable. The paper, Cell-autonomous adiposity through increased cell surface GLUT4 due to ankyrin-B deficiency’, was published in the Proceedings of the National Academy of Sciences.

7.6 million cases of obesity-related diseases by 2035

More than 7.6 million new cases of disease linked to being overweight or obese could be diagnosed in the UK during the next 20 years, according to the Obesity Health Alliance. If the worrying trend in obesity continues, around 40 million adults in the UK could be overweight or obese by 2035, with 45 percent of adults in the lowest income bracket being obese.  

Obesity Day to highlight growing obesity epidemic in Europe

The growing obesity epidemic, which is predicted to affect more than half of all European citizens by 2030, will be the focus of European Obesity Day to be held on 21 May. According to World Health Organisation, obesity is one of the greatest public health challenges of the 21st century. Its prevalence has tripled in many countries of the WHO European Region since the 1980s, and the numbers of those affected continue to rise at an alarming rate.

Obesity linked to increased food energy supply

The obesity epidemic is increasing in many countries in step with increases in the food energy supply, according to a study published in the Bulletin of the World Health Organization. The study, by authors based in New Zealand and the US, analysed increases in the food energy supply and obesity in 69 countries (24 high-, 27 middle- and 18 low-income) and found that both body weight and food energy supply had increased in 56 (81%) of them between 1971 and 2010.
