Study Shows That A Quarter of People Worldwide Will be Obese by 2045

Owing to current lifestyle trends, almost a quarter (22 per cent) of the people in the world will be obese by 2045, up from 14 per cent in 2017, researchers say.

Owing to current lifestyle trends, almost a quarter (22 per cent) of the people in the world will be obese by 2045, up from 14 per cent in 2017, researchers say.

The startling projections, presented at 2018 European Congress on Obesity in Vienna, also demonstrated that the prevalence of diabetes will increase from 9.1 percent to 11.7 percent by 2045, which will result in one out of eight people around the world to suffer from Type-2 diabetes.

“These numbers underline the staggering challenge the world will face in the future in terms of numbers of people who are obese or have Type-2 diabetes or both. As well as the medical challenges these people will face, the costs to countries’ health systems will be enormous,” said Alan Moses, Chief Medical Officer at the Novo Nordisk — a Denmark-based healthcare company.

Overweight means having more body weight than is considered normal or healthy for one's age or build, while obesity is the condition of the excess amount of body fat with a body mass index (BMI) of over 30.

According to the researchers, in order to prevent the prevalence of Type-2 diabetes from going above 10 percent in 2045, global obesity levels must be reduced by 25 percent.

For the study, the population of all countries from 2000-2014 was divided into age groups which were further subdivided on the basis of body mass index (BMI). The diabetes risk for each age and BMI group was then applied, allowing estimations of diabetes prevalence for each country each year.

The researchers said that immediate action will not result in reversing the epidemic of diabetes and obesity quickly, however, it is essential to prevent new cases of obesity and diabetes.

“Despite the challenge all countries are facing with obesity and diabetes, the tide can be turned – but it will take aggressive and coordinated action to reduce obesity and individual cities should play a key role in confronting the issues around obesity, some of which are common to them all and others that are unique to each of them,” Moses said.

Obese? Blame it on Fat Cells’ Expansion

You have heard about obesity or accumulation of fat but do you know that nutrition is not the only factor driving obesity in our kids?

According to researchers, the mechanics of ‘cellular expansion’ plays a pivotal role in fat production.

To understand how obesity develops, a team from Tel Aviv University in Israel used state-of-the-art technology to analyse the accumulation of fat in the body at the cellular level.

“We wanted to find out why a sedentary lifestyle results in obesity, other than making time to eat more hamburgers,” said professor Amit Gefen from Tel Aviv University’s department of biomedical engineering.

“We found that fat cells exposed to sustained, chronic pressure – such as what happens to the buttocks when you are sitting down – experienced accelerated growth of lipid droplets, which are molecules that carry fats,” Gefen added.

Contrary to muscle and bone tissue, which get mechanically weaker with disuse, fat depots in fat cells expanded when they experienced sustained loading by as much as 50 percent. This was a substantial discovery.

The researchers discovered that, once it accumulated lipid droplets, the structure of a cell and its mechanics changed dramatically.

Using a cutting-edge atomic force microscope and other microscopy technologies, they were able to observe the material composition of the transforming fat cell, which became stiffer as it expanded.

This stiffness alters the environment of surrounding cells by physically deforming them, pushing them to change their own shape and composition.

“When they gain mass and change their composition, expanding cells deform neighbouring cells, forcing them to differentiate and expand,” he explained.

This proves that you are not just what you eat. You are also what you feel – and what you are feeling is the pressure of increased weight and the sustained loading in the tissues of the buttocks of the couch potato.

If you can learn to control the mechanical environment of cells, you can then determine how to modulate the fat cells to produce less fat, Natan Shaked from Tel Aviv University noted.

The team is now creating a platform to develop new therapies and technologies to prevent or even reverse fat gain, said the research published in the Biophysical Journal. (Bollywood Country)
