A World of Weight: 30 Most Obese Countries in the World [2023 Update]

When we talk about the most obese countries in the world, we’re really talking about places where a large portion of the population has packed on too much fat. However, weight on its own doesn’t tell the whole story.

For instance, a tall guy who’s 6 feet 2 inches and 80 kg is in a different boat than someone who’s 5 feet 6 inches and the same weight. That’s where BMI, or Body Mass Index, comes into play. It’s a handy little formula that takes both height and weight into consideration.

According to the World Health Organization, if your BMI hits 30 or above, you’re overweight. If it’s 30 or more, you’re considered obese. And here’s a startling fact: since 1975, worldwide obesity has tripled. In 2016, nearly 40% of the global adult population was overweight. About 13% of all adults were straight-up obese. Even kids aren’t spared. A whopping 39 million kiddos under 5 are obese, with 340 million aged 5-19 either obese or overweight.

And here’s a grim truth: in certain countries, more people die from obesity-related issues than from being underweight. In 2017, obesity was the reason behind 4.72 million deaths worldwide. Fiji, Bahrain, and American Samoa are the hardest hit, with alarming percentages of deaths linked to obesity.

But what’s causing this global weight gain? A big part is our love for calorie-laden foods, especially those sweet drinks and high-fat snacks. On average, we’re now consuming around 600 calories more per day than we did in the 1960s. Major brands like Coca-Cola, PepsiCo, Mondelez, McDonald’s, and Yum! Brands are some of the culprits, with their sugar-packed offerings.

Another issue? Our increasingly sedentary lifestyles. We’re all guilty of spending hours glued to screens or opting for Uber rides instead of a brisk walk. Plus, certain health issues, like diabetes or hyperthyroidism, can make putting on weight easier.

However, all’s not lost. Cutting back on sugar and upping our intake of fresh fruits and veggies can make a difference. A good ol’ fashioned walk can also help. For adults, a daily total of 150 minutes of walking is a good starting point. Kids should aim for an hour of physical activity.

As a society, we can also push for changes. Things like taxing sugary products, promoting healthier alternatives, and limiting junk food advertising aimed at our young ones. Making healthier food options both accessible and affordable is crucial. After all, it’s high time we took a stand against obesity!
