This blog discusses this year’s theme, the origin of World Obesity Day, its importance and the causes and strategies for preventing obesity. 

World Obesity Day 2025: Theme 

This year’s theme is ‘Changing Systems, Healthier Lives’. It focuses on addressing the broader systemic factors responsible for obesity such as food systems, healthcare policies and environmental influences. 

It shifts the focus from individual responsibility of preventing obesity and highlights the need for collective action towards transforming our health, food and government systems to bring a change that overcomes the obesity crisis and promotes healthier living.

• World Obesity Day 2022 Theme: Everybody Needs to Act
• World Obesity Day 2021 Theme: Everybody Needs Everybody
• World Obesity Day 2020 Theme: The Roots of Obesity Run Deep

Origin of World Obesity Day 

World Obesity Day was initiated on 11th October 2015 by the World Obesity Federation to raise awareness about obesity and its health consequences. In 2020, the date was shifted to 4th March to encourage global efforts and enhance the effectiveness of the campaign. 

Since its origin, the day has now turned into a significant global movement achieving a remarkable reach with social media campaigns and events engaging millions of people worldwide. For example, the 2021 campaign witnessed a considerable increase in engagement, showing a growing global commitment towards addressing obesity. 

The day continues to bring nations together to implement strategies for the prevention and treatment of obesity.

What is Obesity?

Obesity is a health condition in which an individual has excessive body fat. It’s usually measured in Body Mass Index (BMI) which takes into account the weight and height of an individual. Having a BMI of 30 and above puts individuals in the obese category. It’s often caused by consuming more calories than their body can burn, but other factors such as genes and medical conditions also play a role.

Common Misconceptions about Obesity 

Here are the five most common misconceptions related to obesity:

Misconception 1: Obesity is just about overeating and lack of willpower

Fact: Obesity is a complex condition triggered by genetic, environmental and emotional factors, not just poor eating habits. 

Misconception 2: Obesity is only a cosmetic issue

Fact: Obesity is a serious medical condition responsible for other chronic diseases. 

Misconception 3: Only adults can be obese

Fact: WHO reported approximately 37 million children below 5 years of age as overweight. 

Misconception 4: People with obesity don’t care about their health

Fact: Obese individuals face body-shaming, causing a detrimental effect on their mental well-being. The social stigma associated with obesity and the lack of proper support leave them suffering. 

Misconception 5: Obesity can be tackled with a quick-fix diet 

Fact: Tackling obesity requires healthy lifestyle changes including proper diet, exercise, stress management and adequate sleep. 

Importance of World Obesity Day 

As per the World Health Organization (WHO), more than 2 billion people worldwide are affected by obesity. It is a complex, chronic disease that contributes to other diseases including high blood pressure, high cholesterol, heart disease, liver disease, sleep apnea and different types of cancers.  Despite its rising cases worldwide, it is not considered a global health concern. 

World Obesity Day is a significant event that challenges the misconceptions surrounding obesity and brings an opportunity to educate the public about its causes. It calls for collective action from individuals, governments, and organisations globally to create healthier environments that promote weight management. 

Causes of Obesity

Obesity is a complex and chronic disease linked to numerous factors. Some of the common causes of obesity include:

Genetics 

Genetics play a vital role in determining how our bodies store fat, burn calories and regulate appetite. Some people inherit genes that help them burn fat faster. On the other hand, in some cases the inherited genes can make the metabolism slow, resulting in more weight gain. 

Sedentary Lifestyle and Lack of Physical Activity

Having a sedentary lifestyle and not indulging in any type of physical activity can result in weight gain. When it becomes uncontrollable, obesity kicks in. The worst part of it is that obesity becomes a contributor to other lifestyle diseases such as diabetes and hypertension. 

Hormonal Imbalance

Certain conditions such as polycystic ovary syndrome (PCOS), hypothyroidism, Type 2 diabetes, hypertension, obstructive sleep apnea and Cushing syndrome can lead to hormone imbalance in the body, leading to obesity. 

Emotional Factors 

Individuals with depression and anxiety often turn to food for comfort, leading to overeating, particularly unhealthy foods. This emotional eating behaviour can result in weight gain over time.

Risk Factors of Obesity

Some of the common risk factors of obesity include:

• Unhealthy Diet: Eating high-calorie foods such as junk food, sugary drinks, and snacks are a significant cause of weight gain, increasing the risk of obesity.
• Poor Sleep: Lack of proper sleep or a poor-quality sleep disrupts the balance of hormones that regulate hunger, causing people to overeat. Thus, making them highly prone to obesity.
• Age: As individuals get older, they lose muscle mass that results in slow metabolism of the body, making it easier for them to gain weight.
• Medications: Certain medications including antidepressants and diabetic medicines cause weight gain as a side effect.

Prevention of Obesity: Top five ways

It is said that prevention is better than cure. Knowing some strategies for effective weight management can help in reducing the chances of developing obesity. Some of these strategies include:

Consuming Adequate Amount of Water 

Studies suggest that drinking water helps in boosting the metabolism of the body by 30%. It enhances the digestion process by breaking down fat and carbohydrates, helping with effective weight management. 

Staying Physically Active 

Indulging in physical activities every day can help in burning the calories you consume. When you burn as many calories as you intake, the likelihood of gaining weight significantly decreases. Try starting with activities that aren’t excessively draining, such as walking, cycling, and yoga, which can be some refreshing ways of staying fit.  

Not Skipping Meals 

Most individuals believe that skipping meals will help them lose weight. However, it’s quite the opposite. Skipping meals increases your appetite, leading to overeating later. Consuming meals at regular intervals keeps you full and energised, enabling proper functioning of the brain and body. 

Adding Fruits and Vegetables to your Diet 

Fruits and vegetables are packed with essential nutrients like vitamins, minerals, and antioxidants. They are also naturally low in calories, meaning you can eat large portions without consuming too many calories. Some fruits and vegetables are also rich in dietary fibre, which adds bulk to your meals, making you feel fuller for a longer time. 

Sleep and Stress Management 

Studies have shown that lack of sleep is one of the major risk factors for obesity. Getting 8 to 9 hours of sleep helps in the proper functioning of the brain and body throughout the day and also eradicates the risk of developing obesity.

On the other hand, stress is inevitable with a fast-paced lifestyle. However, managing it through exercise, a healthy diet, yoga or counselling can keep obesity at bay.

Bottom Line 

This year’s World Obesity Day aims to bring collective efforts of individuals, governments and organisations to control obesity. Knowing about its causes helps us avoid potential risk factors. Besides this, some positive lifestyle changes can help in healthy weight management, reducing the chances of developing obesity.

However, despite practising weight management strategies, it’s difficult for some people to maintain a healthy weight, resulting in obesity. This further increases the risk of numerous health conditions including hypertension and diabetes. Here, medical insurance plans relieve financial pressure from your shoulders, ensuring that all the diagnostic and medical tests will be covered.
