1. 42.5% of Americans are obese. 


Four out of ten American citizens suffer from obesity. If you include the overweight individuals, the percentage rises to 73.6%. The American obesity rate is way too high for comfort, seeing as this disease can cause multiple health problems.

3. Colorado has the lowest obesity rate in the US.

(America’s Health Ranking)

The percentage of obese Americans in Colorado is only 23.8%. Although still not a relatively low number, it is considerably lesser than other US states. So, we can safely state that Colorado is the healthiest American state when it comes to obesity.

The obesity rate varies among different backgrounds, races or ethnicity, ages, and economic status. Some groups of people just have a higher tendency to be obese than others. To find out more about the demographics of obesity in the US, continue reading.

5. At 40.7%, African Americans have the highest obesity rate in the United States. 


On the other hand, white Americans only have an obesity rate of 30.4%. This disparity in American obesity statistics is controversial, but likely factors include environment, diet, and exercise. African Americans have a higher fast food consumption than white Americans, as shown by a fast food and obesity statistics report done by the CDC, so this could be a contributing factor.

6. At 12.7%, Asian individuals have the lowest obesity rate in the United States. 


Having an obesity percentage that’s lower than the American average in each state, the Asian population of the country is undoubtedly the least obese. Their cultural eating habits may contribute to this, which includes a lesser consumption of fast food.

7. Almost 38% of American Indian citizens have obesity issues.


Obesity trends in America show that American Indian individuals are less obese than African Americans, but they still have a high rate of this medical condition. Based on recent obesity trends in the US, 37.9% of American Indians are obese.

8. 44.8% of American adults between the ages of 40 and 59 are obese. 


They are the adult age group with the highest obesity rate in the United States. Next to them, obesity rates in America show that adults aged 60 and above come next at 42.8%, and those between the ages of 20 and 39 come last with a 40% adult obesity rate. As usual, when we talk about obesity in America, statistics like these are pretty alarming.

In the United States, 40.4% of women are obese, while men have an obesity rate of 35%. There are also more severely obese women than men, with the former at 9.9% and the latter at 5.5%. However, it is worth noting that the male percentage (38.7%) outweighs the female one (26.5%)

10. People with low income tend to be more obese. 

(Public Health)

Trends clearly show a higher number of low-income individuals with obesity problems. To be exact, 30.6% of those who have a yearly income lower than $36,000 are obese. That must be because eating healthy has become increasingly more expensive.

Childhood Obesity Statistics

Obesity can start as early as childhood in many people—a fact that is concerning and alarming. Based on statistics, improper nutrition is the number one factor for childhood obesity. Children should be taught a healthy lifestyle and be introduced to wellness.

11. Over 150 million children in the world are obese. 

(Childhood Obesity Foundation) 

The global statistics on childhood obesity show that there are 150 million obese children around the world. This number is problematic and it is estimated to increase in the coming years, according to childhood obesity trends. In the next four years, the number of obese children will grow to over 200 million.

12. Childhood obesity is expected to reach 254 million by 2030.

(World Obesity)

Before reaching this astounding number, as calculated from current child obesity statistics, it is first expected to reach 206 million by 2025. Given our everyday eating habits and lack of efforts to prevent obesity, this is not far from happening. According to predictions by the World Obesity Federation taken from current obesity data, China will have the highest number of obese individuals aged 5 to 19 by 2030. 

13. 14.4 million American children and adolescents are obese.


As mentioned above, obesity is not something to take lightly, especially not when the person who suffers from it is only a child. When it comes to childhood obesity statistics in America, 14.4 million kids are reported to be obese.

14. 21.2% of those aged 12 to 19 years old are obese. 


This age group has the highest prevalence of childhood obesity in the United States. Children between the age of 6 and 11 come next at 20.3%, and those between 2 and 5 years old come last at 13.4%. Therefore, educating oneself on childhood obesity facts and statistics is essential, especially since obese children are highly likely to grow up into obese adults. 

15. Hispanic and African American children have the highest prevalence of obesity. 


There is a difference in obesity trends among various age groups, but there is also a difference among different races. For example, the percentage of obese Hispanic children is 25.6%, while Black children have a rate of 24.2%. Both of these childhood obesity stats surpass the 16.1% prevalence rate among white children.

16. Asian children have the smallest percentage of childhood obesity. 


While Hispanic children have an obesity rate of 25.6%, only 8.7% of Asian children in the United States are obese. Obesity is a big problem as diabetes stats show 86% of type 2 diabetes patients are overweight.

17. Kentucky has the highest obesity rate among youth aged 10 to 17.

(State Of Childhood Obesity) 

According to Kentucky’s adolescent obesity statistics, 23.8% of youth aged 10 to 17 are obese. This rate has steadily increased from 19.6% in 2016. That’s why it comes as no surprise that the state ranks fifth in adult obesity, with 36.5% of its adult population being obese. One of the facts about childhood obesity is that obese children likely grow up to be obese adults. 

18. Utah has the lowest obesity rate among youth aged 10 to 17. 

(State Of Childhood Obesity) 

The youth obesity rate in Utah is 9.6%, which is the lowest among all states of the United States. Unfortunately, this rate hasn’t changed much from 9.5% in 2016. However, it’s worth reporting that despite having the lowest youth obesity rate, 29.2% of adults in Utah are obese.

Obesity increases the likelihood of developing many health conditions, such as diabetes, hypertension, and heart disease. In the following statistics, we will focus on the correlation between obesity and heart disease.

Another one of the many facts about obesity is that it can lead to fat buildup in your arteries. If these arteries get clogged or damaged, heart disease can ensue. This severe threat is why obesity is nothing to scoff at. According to CDC obesity statistics, obesity is one of the five top factors that increases your chances of developing heart disease. 

20. Almost 18 million individuals die yearly because of heart disease.


When it comes to the number of deaths worldwide caused by heart disease, the total sum reaches 17.9 million. If the worldwide obesity rate decreases, so would this tragic number, seeing as obesity increases the risk for heart failure.

21. In the US, a person dies of heart disease every 30 seconds.


This really makes you wonder how much of these heart disease deaths have stemmed from obesity. We can’t know the exact number for sure, but we know that the effective prevention of obesity can save many lives.

Globally, obesity has become an epidemic with the number of deaths it causes annually. Obesity used to be a problem only in high-income countries, but as we’ve seen from obesity statistics in 2021, its reach has extended into middle and low-income countries now. 

25. At 61%, Nauru has the highest obesity rate in the world.
