Obesity increases greenhouse gases, new study claims

A new study, published in the journal of The Obesity Society, reveals the rise in obesity rates is making it more difficult to bring down the carbon dioxide emissions.

"This study makes it clear that we pay a steep price for making it difficult to access care for obesity. Not only does obesity affect the health of the individuals who have it, untreated obesity might also contribute to environmental issues, "f ounder of ConscienHealth Ted Kyle, who was not part of the research, told a news portal.

Researchers of the study hope the finding help provide better treatment for those who are obese. "Our analysis suggests that, in addition to beneficial effects on morbidity, mortality, and healthcare costs, managing obesity can favourably affect the environment as well," Faidon Magkos, of the Department of Nutrition, Exercise and Sports at the University of Copenhagen in Denmark, told a news portal. Adding, "This has important implications for all those involved in the management of obesity."

According to the study's results, obesity is linked with close to 20 per cent greater greenhouse gas emissions compared to those with a normal weight. "Harmonizing data from epidemiology (prevalence rates of obesity), physiology (total energy intake and expenditure) and environmental science (carbon dioxide emissions from different sources) is not a straightforward task, and we emphasize that our estimates are not intended to be precise, but rather be reasonable enough," Magkos told a news portal.

Another study found obesity can increase the risk of death due to non-communicable diseases. However, the risk factors are different for men and women. "This study shows just how harmful carrying excess weight can be to human health, and that women and men may experience different diseases as a result," first author Jenny Censin, from the University of Oxford, told a news portal. Adding, "Given the compelling evidence of harm that arises as a consequence of obesity across a broad range of diseases that result in death, our findings highlights the critical need for public health measures to stem the tide of obesity."

Obesity can also cause fat to accumulate in the lungs. "Our research team studies the structure of the airways within our lungs and how these are altered in people with respiratory disease," study's author John Elliot, a senior research officer at Sir Charles Gairdner Hospital in Perth, Western Australia, told a news portal. Adding, "Looking at samples of lung, we spotted fatty tissue that had built up in the airway walls. We wanted to see if this accumulation was correlated with body weight."
