The 30 Most Obese Countries in the World

Obesity is one of the major causes of death in the world that is preventable and treatable. The percentage of obese people has tripled since 1975.

Obesity is measured by computing the Body Mass Index (BMI) of an individual. With this data, it is possible to determine the national obesity rate per country.

Of 195 countries in the world today, we have curated a list of the top 30 most obese countries in the world, which is derived from the Central Intelligence Agency’s list of Obesity – Adult Prevalence Rates.

Frequently Asked Questions

What is obesity?

BMI

In simple terms, obesity is described as a person who is overweight according to their body mass index (BMI). The BMI indicates whether a person’s weight is proportional to their size.

A person can be overweight because of water content, muscle, or bone. However, in obesity, the body is considered overweight because of too much body fat than normal.

Obesity doesn’t happen overnight. It happens over time as a person overeats and lacks exercise.

If a person’s BMI is between 25 and 30, it is considered overweight, while a BMI above 30 is obese. Aside from computing the BMI, obesity can be determined with visible signs including excess body fat.

What are the causes of obesity?

The number one cause of obesity is eating too many fatty foods, including junk foods, sweets, meat, and processed food. Moreover, excessive alcohol consumption also leads to obesity.

Aside from excessive food intake, obesity is associated with a lack of exercise. Food and exercise are some controllable factors that can help prevent or treat obesity when modified.

Other causes of weight gain are underlying medical conditions such as hypothyroidism, pregnancy, medication, and metabolism. Moreover, genes and way of living contribute to weight gain.

How is overall health affected by obesity?

A person’s overall quality of life is affected by obesity since it interferes with their daily activities. For instance, obese people can have difficulty breathing and exercising and may feel ashamed and isolated.

Low self-esteem can have an impact on one’s productivity.

Besides affecting one’s quality of life, obesity can also cause many health problems, such as heart disease, cancer, osteoarthritis, asthma, liver disease, kidney disease, pregnancy complications, and sleep apnea.

How can obesity be treated?

The most effective way to treat obesity is lifestyle modification, which means eating a balanced diet and exercising regularly.

A person’s kilojoule intake should be reduced, and healthier food options must be prioritized, such as eating more fruits and vegetables.

A combination of diet and exercise will have the biggest impact. Thus, doing moderate to intense exercise is recommended, including walking, jogging, swimming, and playing various sports.

Keep in mind there is no quick treatment for obesity, so it will take a lot of time and patience to reach one’s weight goal. However, there are other ways that can aid in weight loss such as anti-obesity drugs and surgery.

What are the recommended food portions?

The Centers for Disease Control (CDC) has some recommendations on the proper food size consumption.

For instance, the recommended serving of rice or pasta per meal should be about the size of a tennis ball, while chopped raw vegetables or fruit should be like a baseball.

If you were to eat a serving of beans, it should be similar to the size of a billiard ball. For nuts or dried food, try eating a small portion like a golf ball.
