When you think of climate change, you think of melting ice-caps, rising temperatures, and raging wildfires. When you think of climate change and public health, you think of heat waves and poor air quality. In regards to climate change, the last thing you would connote that with is obesity.

However, a new study has found that climate change can cause an increased risk of obesity.

Climate Change is Causing Obesity

“When temperatures rise, people typically become less physically active and that’s associated not only with obesity prevalence but also with more use of gas-powered transportation,” Christian Koch, MD, PhD, study co-author and the director of the Fox Chase Cancer Center’s division of endocrinology.

Research published in the journal Hormone and Metabolic Research suggests that greenhouse gas emissions from the burning of fossil fuels have significantly increased in the last 70 years.

According to researchers from Fox Chase Cancer Center in Philadelphia, this upward trajectory will continue and this will then lead to severe weather events. This, in turn, will trigger more sedentary behavior, especially among people who have obesity.

The researchers also reveal that climate change will also trigger subsequent use of fossil-fuel-dependent transportation among people with obesity.

Therefore, as climate change worsens, obesity is likely to increase. When it does, it will continue to negatively affect the environment even more than it already has.

There’s also a cancer risk

The researchers also noted that there’s also an increased risk for cancers that are associated with obesity. How so? Obesity is often linked to higher insulin levels, and this factor has been associated with cancer development.

Secondly, fat tissue in women can produce estrogen, and this has been linked to breast, ovarian, and endometrial cancers.

According to Dr. Koch, these cancers include breast, endometrial, esophageal, colorectal, and liver cancers, as well as cancers of the thyroid, pancreas, kidney, and gallbladder.

“With this commentary, we’re trying to raise awareness about how things interconnect,” says Dr. Koch. “People need to know about these associations.”

Tackling obesity and climate change

obesityThe first step, according to Dr. Koch, is acknowledging that there’s a problem. Once we do that, we can then properly address the issue.

Thankfully, because everything is so connected, effectively addressing one issue is sure to positively affect the others.

“We know there is a bidirectional relationship between climate change and obesity,” says Dr. Koch. “That means strategies that improve the health of each individual can also have an effect on the planet.”

Therefore, it’s important for communities to encourage healthy lifestyle habits that can address obesity. For example, encouraging walking and cycling won’t only keep people active, but it will also help to reduce their carbon footprint. Secondly, adopting a plant-based diet won’t only help to curb obesity rates, but it’s also much better for the environment.
