The world has seen an alarming rise in obesity rates over the past decade. People all over the world are becoming less active and have access to high-calorie high-fat foods. According to the World Health Organization, it is estimated that over 650 million adults and 379 million children and adolescents are obese worldwide. The severity of this case is different from one country to another.

Obesity is determined by a body mass index, which calculates weight divided by height. A BMI of over 30 is considered obese. This major health concern is linked to numerous diseases, including diabetes, heart disease, certain types of cancer, and even mortality.

To help tackle this global crisis, we have compiled a comprehensive list of the top 20 obese countries. This list considers factors such as population size, lifestyle habits, and access to healthcare. We’ll also provide an overview of each country’s current obesity rate, so you can better understand what’s going on. With this list, you’ll see which countries are leading the way in fighting obesity and which are still lagging.

Obesity Rate: 46%

Kiribati is a tiny island with a population of about 100,000 people. Kiribatians are facing a major health crisis due to the rising prevalence of obesity. Studies have shown that the leading cause of weight gain in Kiribati is increased caloric intake combined with relaxed island living.

Main Causes of Obesity in Kiribati

obesity island

With more people eating energy-dense, large-scale manufactured groceries and less engaging in physical activity, it’s not surprising that the level of obese individuals is increasing. Little access to affordable and nutritious meal choices also contributes to the problem.

Many of Kiribati’s inhabitants live in poverty and cannot afford the fresh, healthy nourishment they need. This means they are more likely to turn to cheaper and more readily available menu options.

  • High intake of convenience meals
  • Lack of access to healthy nutrition due to poverty
  • Gene variant that affects size.

  • No access to physical activity (No gyms or recreational facilities)


palau

3. Palau

Obesity Rate: 55%

Obesity is a significant issue in Palau, with more than half of the population experiencing an obesity epidemic. This is largely due to the country’s limited availability of wholesome meal options. The fact that Palau is made up of 500 islands makes it difficult to distribute healthy food to all areas, causing 20,000 citizens to have limited access to nutritious options.

Processed food has a longer shelf life, making importing and exporting easier. It is also generally cheaper to produce than other types of food because it is made in large quantities using mass-production methods. This makes it an attractive option for many consumers. However, processed food is often high in added sugars, salt, and unhealthy fats, which can contribute to negative health outcomes such as obesity and chronic diseases.

Main Causes of Obesity in Palau

obesity island

Diet is a major contributing factor for weight gain in Palau. Instead of using energy to hunt, fish, and gather, Palauans have traded tradition for convenience. Conserving energy and poor nourishment result in less physical activity on the remote Pacific island.

  • Diet high in carbohydrates and starches, with few fresh fruits and vegetables
  • Lacks essential nutrients and vitamins
  • Low physical activity


Cook Islands

2. Cook Islands

Obesity Rate: 55%

A significant portion of their diets includes white rice, processed instant noodles, foreign-imported junk food, and sodas with almost no fresh fruits and vegetables.

  • Unhealthy diet
  • Lack of access to fresh food

Contributing Factors of Worldwide Obesity

Covid-19 has dramatically impacted the global weight issue, with the number of obese people increasing significantly in the past year. This is due to the restrictions imposed by the pandemic and lockdowns, which have led to people becoming more sedentary and spending more time indoors. With fewer outdoor activities and exercise opportunities, people are more likely to consume unhealthy snacks and sugary drinks. This, in turn, causes people to gain weight and become overweight or even obese.

Furthermore, the coronavirus pandemic has caused a financial strain on many households, leading to people relying on cheaper, processed foods that are often high in fat, salt, and sugar. This leads to a further increase in obesity levels, which can escalate the number of severe health problems.

Countries Still Lagging Behind

Many nations currently plagued with major overweight cases are not directly addressing the issue. These governments have poor public health policies, and their citizens lack access to proper healthcare. This makes it difficult for them to prevent and treat obesity once it escalates in their population. The Lancet by the Global Burden of Disease studied countries with the highest rate of obesity by population. 

Top 10 countries with the highest number of fat people

Developed countries may have better access to healthcare and other resources, but they are still at risk of this global health epidemic. It is predicted that the prevalence of obesity in developed countries will continue to rise in the next decade. The statistics in children point to an even graver future.

As the world population increases, so does the predominance of obesity. Obesity is becoming more prevalent globally, with rapid growth in the Bahamas (30%), New Zealand (31%), Iraq (30%), Canada (28%), Australia (28%), and the United Kingdom (26%). These countries, and many others, are experiencing the dangerous health effects of adiposity, such as heart disease and diabetes.

Countries Leading the Way in Tackling Obesity

In many cases, it’s not just important to know which countries have obesity problems but also the ones dealing with it the most efficiently and productively. Solving obesity is more than just eating a healthy diet and exercising; it’s also about improving public health policies and better access to healthcare.

The slimmest nations of the globe, according to OECD:

  1. Madagascar (BMI of 21.1)
  2. Eritrea (BMI of 21.1)
  3. Ethiopia (BMI of 21.2)
  4. Timor-Leste (BMI of 21.3)
  5. Burundi (BMI of 21.6)
  6. Japan (BMI of 21.8)
  7. China (BMI of 21.9)
  8. India (BMI of 21.9)
  9. Bangladesh (BMI of 22.0)
  10. Burkina Faso (BMI of 22.1)

The people in these countries are used to walking or biking regularly to school or work and routinely engaging in sports or exercise activities. There is also a strong emphasis on education about nutrition. This includes teaching children the importance of eating wholesome foods and the dangers of unhealthy diets. These factors have helped these countries effectively tackle obesity and promote a healthier lifestyle.

Countries in Scandinavia have effective measures in place to combat their local obesity incidents. Healthy dietary habits help residents get the essential nutrients without worrying about consuming too much fat or sugar. Secondly, regular physical activity is a staple in regions like Norway, Sweden, and Finland.

To reverse the obesity epidemic, it’s important to understand its causes. Once we get a better understanding of these factors, we can start to implement solutions. And most importantly, we can work together to encourage people to get more active, eat healthier, and lead a more balanced way of living.

Solutions to Obesity

One possible solution for treating obesity is pharmacotherapy, which involves using medications to reduce appetite and control cravings. However, diet and exercise are typically the primary methods for addressing these issues. Unfortunately, most diets, exercise plans, and medications have been found to be ineffective ways to lose weight. These nonsurgical methods only account for a modest 5-10% excess body weight loss.

Bariatric surgery, also known as weight loss surgery, is considered the most effective resolution for obesity. There are several types of bariatric surgery, including laparoscopic and endoscopic procedures. Laparoscopic surgery is a minimally invasive procedure involving making small incisions in the abdomen to reduce the size of the stomach and change how the intestines function. On the other hand, endoscopic techniques are scarless procedures in which a small tube is inserted through the mouth to remove excess fat from the digestive tract. Both types of bariatric surgery have been shown to help individuals lose weight and improve their overall health outcomes.

The rank #1 medical tourism operator, Mexico Bariatric Center®, offers VIP packages for patients who cannot afford it to receive this life-saving operation in Tijuana and Guadalajara, Mexico.

Making lifestyle changes, such as eating a healthy diet and getting regular physical activity, can help prevent or reduce obesity. Education and support can also be useful in helping individuals make changes to their habits. The most effective approach to treating obesity typically involves a combination of behavior modification, dietary changes, physical activity, and pharmacotherapy or bariatric surgery as needed.
