1. What is Obesity

Obesity is a medical condition that occurs when a person has an excessive amount of body fat, which can lead to negative health outcomes. It is typically defined as having a body mass index (BMI) of 30 or higher. BMI is calculated by dividing a person’s weight in kilograms by the square of their height in meters.

Obesity can lead to a variety of health problems, including type 2 diabetes, heart disease, stroke, certain types of cancer, and other chronic conditions. The economic costs of obesity are also substantial, including medical costs and lost productivity.

The high rates of obesity in the United States can be attributed to various factors, including poor diet, lack of physical activity, genetics, and environmental factors such as limited access to healthy food and safe places to be physically active. Addressing obesity will require a comprehensive approach, involving individuals, families, communities, healthcare providers, and policymakers working together to promote healthy lifestyles and create supportive environments for healthy choices.

3. The chronic reasons behind obesity in USA

The United States is often associated with junk food due to the abundance and popularity of fast food chains, convenience stores, and processed snack foods. This association has been influenced by several factors.

One factor is the rise of fast food chains in the mid-20th century, including McDonald’s, Burger King, and KFC, which made it easy and affordable for people to grab a quick, high-calorie meal on the go.

Another factor is the availability of processed foods, such as potato chips, candy, and soda. These products are often high in sugar, salt, and unhealthy fats and marketed aggressively to consumers through advertising and packaging.

Busy lifestyles are another reason why fast food and processed foods are popular. These foods require little preparation or cooking, making them a convenient choice for those with limited time.

Cultural attitudes also play a role, as some parts of American culture glorify indulgence and excess, which may contribute to the popularity of junk food. Additionally, many Americans have grown up eating these types of foods and may have developed a taste for them.

It is worth noting that the association between the United States and junk food is not absolute, and many Americans do prioritize healthy eating habits. However, the prevalence of fast food chains and processed foods in American society has led to a perception that the country has a close connection to junk food.

4. What is the data says

According to the Centers for Disease Control and Prevention (CDC), the latest available data on obesity in the United States is from 2019. Here are the statistics:

  • The prevalence of obesity among adults in 2019 was 42.4%.
  • The prevalence of severe obesity among adults in 2019 was 9.2%.
  • The prevalence of obesity among youth aged 2-19 in 2017-2018 was 19.3%.
  • The prevalence of severe obesity among youth aged 2-19 in 2017-2018 was 6.1%.

It’s important to note that these statistics are from before the COVID-19 pandemic, and there have been concerns that the pandemic may have worsened the obesity epidemic in the United States.

5. The main factors behind obesity

There are many factors that can contribute to obesity, including:

  1. Overeating: Consuming more calories than the body needs can lead to weight gain and obesity.
  2. Lack of physical activity: Sedentary lifestyle can lead to lower metabolic rate, and burn fewer calories.
  3. Genetics: Certain genes and family history can influence body weight and the likelihood of becoming obese.
  4. Environmental factors: Exposure to certain chemicals or living in a neighborhood with limited access to healthy foods or safe places to exercise can contribute to obesity.
  5. Medical conditions: Some medical conditions such as hypothyroidism, Cushing’s syndrome, or Prader-Willi syndrome can cause weight gain and obesity.
  6. Medications: Certain medications such as antidepressants, antipsychotics, and corticosteroids can cause weight gain and contribute to obesity.
  7. Psychological factors: Stress, depression, and other mental health conditions can lead to overeating and contribute to obesity.

It’s important to note that obesity is a complex condition, and multiple factors can contribute to its development. A combination of genetics, environmental factors, and lifestyle choices may all play a role.

6. What is the situation of the neighborhood ?

The World Health Organization (WHO) reports that obesity is prevalent in both the United States and Canada, with the United States having a slightly higher prevalence than Canada. In 2016, approximately 36.2% of American adults and about 29.4% of Canadian adults were considered obese. Unfortunately, obesity rates have been on the rise in both countries for several decades, due to a combination of factors, including genetics, diet, physical activity, and socio-economic status. Those with lower socio-economic status may face barriers to accessing healthy foods and opportunities for physical activity, which can contribute to higher obesity rates in certain populations..

Both the USA and Canada have implemented policies and programs aimed at reducing obesity rates. These initiatives promote healthy eating habits and increase opportunities for physical activity. However, their effectiveness may vary depending on cultural and societal norms, as well as individual preferences and behaviors

7. The precautionary measures to prevent obesity

Obesity can be prevented through a combination of healthy eating habits, regular physical activity, and other lifestyle changes. Here are some tips to prevent obesity:

  • Maintain a healthy diet: Incorporate a balanced diet that is rich in fruits, vegetables, whole grains, lean protein, and healthy fats. Avoid processed and sugary foods.
  • Portion control: Be mindful of the portion sizes of your meals and snacks. Use smaller plates, bowls, and cups.
  • Stay hydrated: Drink plenty of water throughout the day.
  • Regular physical activity: Incorporate at least 30 minutes of moderate-intensity physical activity daily, such as brisk walking, cycling, swimming, or dancing.
  • Limit sedentary behavior: Limit your screen time and try to engage in physical activity instead.
  • Get enough sleep: Aim for 7-8 hours of sleep per night.
  • Manage stress: Practice stress management techniques such as meditation, yoga, or deep breathing.
  • Seek professional help: If you have trouble managing your weight on your own, seek the help of a registered dietitian or a healthcare provider.


In summary, obesity is a pressing health issue in the US that has serious consequences for both individuals and society. Although the causes of obesity are multifaceted, lifestyle factors like poor diet and lack of physical activity are major contributors.

To combat obesity, we need to adopt a comprehensive approach that involves education, public policy, and individual lifestyle changes. This could include measures like promoting healthy food options, encouraging physical activity, and providing support and resources to individuals struggling with obesity.

As a society, we have a responsibility to prioritize the health and wellbeing of our communities. One way we can do this is by tackling the obesity epidemic through proactive prevention and treatment, which can improve public health and reduce the burden of chronic diseases associated with this condition.
