What is Obesity?

Obesity is a condition that occurs when an individual’s body weight exceeds the normal or healthy range for their height and age. 

It is commonly caused by consuming more calories than your body requires, which leads to excess fat accumulation in the body.

Obesity can lead to several health problems, including high blood pressure, type 2 diabetes, heart disease, stroke, and certain types of cancer. 

The condition can also affect an individual’s mental health as it may lead to low self-esteem and depression.

While there are no quick fixes for obesity, treatment or prevention involves making lifestyle changes such as adopting healthy eating habits with a balanced diet rich in fruits and vegetables while avoiding junk food and sugary drinks. 

Incorporating regular physical activity into one’s routine can also help promote weight loss.

Causes of obesity

There are several causes of obesity, including genetic factors, lifestyle choices, and environmental influences.

1. Genetics

Research shows that genetics plays a role in determining someone’s likelihood of developing obesity. Some people may have a genetic predisposition towards gaining weight due to their family history and inherited genes.

2. Unhealthy eating habits

The main cause of obesity is an unhealthy diet, which includes consuming foods high in calories.

One of the leading causes of unhealthy eating habits is convenience. For most people, today’s fast-paced lifestyle means we have less time to prepare meals at home, so we often turn to fast food or processed snacks for quick sustenance. These foods are typically high in calories and low in nutrients, leading to excessive weight gain over time.

Another contributing factor to unhealthy eating habits is emotional eating. Many people turn to food as a way of coping with stress or anxiety. This can lead to binge-eating episodes where individuals consume large amounts of high-calorie foods out of boredom or emotional distress.

Additionally, social factors play a role in promoting poor dietary choices. For example, peer pressure can influence individuals into unhealthy food choices, such as indulging in junk food while watching movies or ordering pizza for late-night study sessions.

Lastly, lack of education about proper nutrition also contributes significantly to unhealthy eating habits. Many people do not understand the importance of balanced meals and how different types of foods affect their overall health.  We will go further in-depth about Obesity Causing Foods, in this article.

3. Sedentary lifestyle

A sedentary lifestyle refers to a lack of physical activity or movement throughout the day. 

This could be due to various reasons, such as being stuck at work behind a desk for long hours, watching television for extended periods, playing video games excessively, or simply not engaging in any form of exercise regularly.

When we don’t move our bodies enough, we burn fewer calories than we consume through food and drink, which leads to weight gain over time. 

Moreover, sitting for prolonged periods also negatively affects our metabolism by slowing it down, making it harder for us to burn excess calories.

Furthermore, sedentary behavior can also contribute to increased snacking on unhealthy foods high in sugar and fat due to boredom rather than hunger signals from the body.

Medical conditions

Certain medical conditions like hypothyroidism (under-active thyroid), Cushing’s syndrome (excess cortisol production), Prader-Willi syndrome (a genetic disorder causing constant hunger), and Polycystic ovary syndrome (PCOS), among others, can cause or exacerbate existing obesity cases.

4. Medications

While poor diet and lack of exercise are commonly known causes of obesity, many medications can also contribute to weight gain.

Here are some commonly used medications that may cause weight gain:


Many antidepressant drugs, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs), can cause weight gain. These drugs alter the body’s metabolism, causing it to store more fat.


Corticosteroids like prednisone and methylprednisolone are often prescribed for inflammatory conditions like arthritis or asthma. However, these drugs can lead to increased appetite, fat redistribution, and fluid retention, resulting in weight gain.

Diabetes medications

Some diabetes medications like insulin and sulfonylureas can also lead to weight gain by increasing insulin levels in the body.


Drugs used to treat mental illnesses such as schizophrenia and bipolar disorder can cause significant weight gain due to their effects on the central nervous system.

Birth control pills

Hormonal birth control methods like oral contraceptives have been linked with an increased risk of obesity due to changes in hormone levels that affect metabolism.


These drugs are often prescribed for high blood pressure or heart disease but can cause weight gain by slowing down the metabolism and reducing energy expenditure.

It’s important to note that not everyone who takes these medications will experience significant weight gain, but it’s essential always to discuss potential side effects with your healthcare provider when starting a new medication or adjusting doses.

If you suspect that your medication is contributing to your obesity or worsened symptoms, talk with your healthcare provider about alternative treatment options or lifestyle modifications you could make alongside your medication regimen.

5. Environment

One of the most significant environmental causes of obesity is the availability and accessibility of unhealthy foods. In modern society, fast food restaurants, convenience stores, and vending machines are all over. These outlets often offer cheap, high-calorie snacks and meals that are loaded with sugar, salt, and fat.

Additionally, modern transportation has made it easier for people to live sedentary lifestyles. Cars have replaced walking or biking as primary modes of transportation; elevators have replaced stairs; televisions and computers have replaced physical activity.

The built environment is another critical factor that contributes to obesity. Many urban areas lack safe sidewalks or bike lanes, which makes it challenging for people to engage in physical activity such as walking or cycling regularly.

6. Stress

Stress is a common problem that affects many people around the world. When you are under stress, your body produces hormones such as cortisol and adrenaline. These hormones can cause a number of physical changes in your body, including an increase in appetite and a decrease in metabolism. This combination of factors can lead to weight gain and obesity.

Obesity Causing Foods

Sugar-sweetened beverages 

1. Soda

Soda is a popular drink that is consumed by millions of people worldwide. It is often enjoyed alongside meals or as a refreshing beverage during hot weather. However, it is important to note that soda can contribute significantly to the development of obesity.

One of the main reasons why soda causes obesity is due to its high sugar content. Consuming too much sugar on a regular basis can lead to insulin resistance and eventually type 2 diabetes, which are both risk factors for obesity.

Furthermore, drinking soda does not provide any nutritional value to the body. Unlike whole foods that contain essential vitamins and minerals needed for optimal health, soda only provides empty calories. These calories add up quickly and can cause weight gain over time if not burned off through physical activity.

Another factor that contributes to obesity from consuming soda is the habit-forming nature of this beverage. People often consume more than one can per day without realizing it because they become desensitized to its sweetness over time. This leads them down a path where they need more and more sugar just to feel satisfied.

Lastly, when you drink soda regularly, your body becomes accustomed to receiving an influx of sugar all at once. This causes your blood sugar levels to spike rapidly and then crash shortly after digestion. When this happens repeatedly, it leads to insulin resistance and, eventually, weight gain.

2. Fruit juice

Many people assume that fruit juice is a healthier option than soda or other sugary drinks. However, most commercial fruit juices are heavily processed and contain added sugars or concentrates, which make them just as unhealthy as soda.

In fact, consuming too much fruit juice has been linked to an increased risk of obesity and type 2 diabetes. This is because the body processes the sugar in fruit juice differently than it does the fiber in whole fruits.

When you consume whole fruits, the fiber slows down digestion and helps keep you feeling full for longer periods of time. However, when you drink fruit juice, all of the fiber has been removed, and your body absorbs the sugar more quickly. This can lead to spikes in blood sugar levels and increased feelings of hunger.

Additionally, many people underestimate how many calories they are consuming when they drink fruit juice. A single cup of orange juice can contain up to 26 grams of sugar, which is equivalent to 6 teaspoons of sugar, or a glass of Coca-Cola.

To avoid obesity caused by excessive consumption of fruit juices, it’s best to limit your intake or switch to whole fruits instead.  

3. Sports drink

Sports drinks are commonly marketed as the perfect solution for athletes and fitness enthusiasts who need to stay hydrated and replenish their electrolytes. However, these beverages can also be a major contributor to obesity.

One of the main reasons why sports drinks are linked to weight gain is because they contain high amounts of sugar. Many sports drinks have added sugars in the form of high-fructose corn syrup or other sweeteners, which can quickly add up in calories when consumed regularly.

Moreover, many people mistakenly believe that sports drinks are necessary for hydration during physical activity or exercise. While they do provide some benefits in terms of electrolyte replacement, water is still the best choice for staying hydrated and avoiding unnecessary calories.

4. Refined grains (white bread, pasta)

These types of grains have been stripped of their natural nutrients, including fiber and protein, leaving only the starchy endosperm. Although refined grains may taste good, they can be detrimental to one’s health.

One major concern with consuming refined grains is that they can cause obesity. Studies show that individuals who consume a diet high in refined carbohydrates tend to gain more weight than those who eat whole-grain products. The reason for this is that refined carbs spike blood sugar levels quickly, causing an insulin release which promotes fat storage.

Additionally, refined grains also lack the necessary fiber required for proper digestion. Fiber helps to slow down the absorption of sugars into the bloodstream, which prevents sudden spikes in blood sugar levels and keeps us feeling full longer. When we don’t get enough fiber from our diets, we tend to feel hungrier more often and eat more calories overall.

5. Red meat and processed meats 

Red meat is typically higher in calories for a few reasons, including its high saturated fat content.

Processed meats, such as bacon, sausage, and hot dogs, are even worse for your waistline. These meats are often loaded with preservatives and additives that can contribute to weight gain and obesity. 

A study published in the American Journal of Clinical Nutrition found that individuals who ate more processed meats had a higher risk of becoming obese, especially central obesity over time.

So why do red meat and processed meat cause obesity? One reason may be their effect on hormones like insulin and leptin. Insulin helps regulate blood sugar levels by signaling the body to store glucose as fat.

Leptin on the other is a hormone that tells your brain when you’re full. When you eat too much red or processed meat, your body produces more insulin and less leptin, making it harder for you to feel full after meals.

Another reason why these types of meats can lead to weight gain is that they are often served with high-calorie sides like French fries or Mashed potatoes. The combination of red or processed meats with starchy sides can quickly add up to a lot.
