Obesity has become a global epidemic over the past decades.
With unhealthy eating habits, physical inactivity, sedentary lifestyles, and lack of awareness, obesity has now become a public health crisis, affecting millions of people worldwide.
According to the World Health Organization (WHO), obesity is defined as an abnormal or excessive fat accumulation that presents a risk to health.
This article will explore the definition of obesity, its alarming global statistics, the health risks associated with it, and ways to get back in shape.
Definition of Obesity
Obesity is not just about being overweight; it is a complex chronic disease that involves excessive fat accumulation in the body.
The WHO defines obesity as a person having a body mass index (BMI) equal to or greater than 30.
BMI is a simple calculation that measures the weight of a person in kilograms divided by their height in meters squared.
A BMI of 18.5 to 24.9 is considered healthy, 25 to 29.9 is overweight, 30 to 34.9 is obesity class I, 35 to 39.9 is obesity class II, and 40 or more is obesity class III.
World Statistics
Obesity has become a global phenomenon and affects people in both developed and developing countries.
According to the WHO, in 2016, more than 1.9 billion adults aged 18 years and older were overweight, and out of those, over 650 million were obese.
Moreover, 38 million children under the age of 5 were overweight or obese.
The highest prevalence of obesity among adults was in the United States, with approximately 36.2% of the population being obese.
Other countries with high obesity rates include Mexico, which has an obesity rate of 31.6%, New Zealand with 30.7%, and Hungary with 30.4%.
Among children, the highest prevalence of obesity was in the Pacific Island countries and North America.
In Tonga, for example, over 50% of the population is overweight or obese.
Health Risks of Obesity
Obesity is not just a cosmetic issue; it is a health hazard that can lead to various complications, including chronic conditions, disabilities, and premature death.
According to studies, obesity can increase the risk of developing diseases such as type 2 diabetes, high blood pressure, heart disease, stroke, and certain types of cancer. Moreover, obesity can also cause sleep apnea, osteoarthritis, gallbladder disease, and liver disease.
Type 2 Diabetes
Obesity is one of the leading risk factors for type 2 diabetes. Type 2 diabetes is a chronic disease that affects the way the body processes glucose, leading to high blood sugar levels.
Obesity causes the body to become resistant to insulin, a hormone that regulates blood sugar.
As a result, the body cannot use insulin effectively, leading to high blood sugar levels.
High Blood Pressure
Obesity can cause high blood pressure, which can result in heart disease or stroke.
Blood pressure is the force of blood against the walls of the arteries, and when the pressure is high, it can damage the arteries and increase the risk of heart disease and stroke.
Heart Disease
Obesity can cause heart disease, which is a condition that affects the heart and can lead to heart attacks or heart failure.
According to studies, obesity can cause the heart to work harder, leading to an increased risk of heart disease.
Stroke
Obesity can cause stroke, which is a condition that occurs when blood flow to the brain is interrupted. According to studies, obese individuals are at an increased risk of stroke compared to those with a healthy BMI.
Cancer
Obesity can cause certain types of cancer, including breast, colon, and pancreatic cancer.
Studies have shown that obese individuals have a higher risk of developing cancer compared to those with a healthy BMI.
Ways to Get Back in Shape
Obesity can be effectively treated and prevented through healthy lifestyle changes.
The following are some ways to get back in shape and prevent obesity:
1. Eat a Healthy Diet
Eating a healthy diet is the most effective way to prevent and treat obesity.
A healthy diet should include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats.
Avoid sugary drinks, processed foods, and foods high in saturated and trans fats.
2. Exercise Regularly
Regular exercise is another effective way to prevent and treat obesity.
Physical activity helps burn calories and build muscle, which can help reduce body fat and prevent weight gain.
Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
3. Manage Stress
Stress can lead to overeating and weight gain. Manage stress through mindfulness practices such as yoga, meditation, and deep breathing exercises.
4. Get Enough Sleep
Sleep deprivation can lead to weight gain and obesity. Aim for at least 7-8 hours of sleep per night.
5. Seek Professional Help
If you are struggling with obesity, seek professional help from a nutritionist, a dietician, or a healthcare provider. They can provide you with personalized advice and help you develop a plan to get back in shape.
Obesity is a complex chronic disease that has become a global health crisis. It is a risk factor for various chronic conditions, disabilities, and premature death.
However, it can be effectively treated and prevented through healthy lifestyle changes such as a healthy diet, regular exercise, stress management, getting enough sleep, and seeking professional help.
Remember, it's never too late to start living a healthy lifestyle and get back in shape.
