Causes of Obesity

Dr Bhavna Kalvala, The Clinical Research Director of IEEARC Tech explains that Obesity is more than simply a visual issue, A condition known as obesity involves having too much body fat. It is a medical condition that raises the chance of various illnesses and conditions, including heart disease, diabetes, high blood pressure, and some malignancies.


There are numerous causes why some people struggle to lose weight. Obesity typically develops from a combination of dietary, physiological, and environmental factors along with exercise, physical activity, and lifestyle choices.

The good news is that even a small amount of weight loss can help or even stop the health issues linked to obesity. You can lose weight by changing your habits, increasing your physical activity, and eating healthier. Additional alternatives for managing obesity include prescription drugs and weight-loss techniques.


Causes of Obesity

Causes of Obesity

Obesity develops when a person consumes more calories than they expend via regular daily activity and exercise, despite the fact that genetic, behavioural, metabolic, and hormonal factors all play a role in body weight. These extra calories are converted by your body into fat.

The majority of the Indian Population consumes too many calories daily, often from fast food and high-calorie beverages. Obese individuals may consume more calories before feeling satisfied, experience hunger sooner, or consume more food in response to stress or anxiety.

Now because many jobs in nations are far less physically demanding, people there don’t tend to burn as many calories while working. Thanks to conveniences like remote controls, escalators, internet shopping, and drive-through banks, even ordinary tasks require less calories.


Genes play a modest role in body weight, but other variables also affect it, including prenatal and early life impacts, bad diets, excessive television viewing, insufficient sleep, and the environment surrounding our food and physical activity.


What are some of the things that make obesity riskier?

Genes Don’t Define Us

Generally speaking, heredity has significantly less of an impact on obesity than many might think. Genes appear to enhance the chance of weight gain and interact with other risk factors in the environment, such as bad diets and sedentary lifestyles, rather than being the only factor contributing to obesity. Furthermore, healthy lifestyle choices can offset these inherited consequences.

Influences during and after pregnancy

Young life is also crucial. Smoking or being overweight during pregnancy increases the likelihood that the unborn kid will become an obese adult. While being breastfed may reduce the risk, excessive infant weight gain increases the chance of adult obesity.


Unhealthy Diets

One of the biggest contributors to obesity is what has come to be the standard Western diet, which consists of frequent, large meals heavy in refined grains, red meat, unhealthy fats, and sugary drinks. Whole grains, vegetables, fruits, and nuts—foods that are absent in the typical Western diet—appears to aid in maintaining a healthy weight and preventing chronic diseases.


Too much television, not enough exercise, and not enough sleep


Watching television is a significant risk factor for obesity, in part due to the ability of food and beverage advertisements to affect consumer behaviour. Despite the fact that physical activity can prevent weight gain, it is just not practised by enough people worldwide. Sleep deprivation, another hallmark of the Western way of life, is also being recognised as a risk factor for obesity.


Environment, food, and exercise in a toxic way


No one acts in a vacuum, notwithstanding how important individual choices are to health. People’s decisions about what to eat and how to spend their time are greatly influenced by the physical and social environment in which they live. Unfortunately, this environment has grown poisonous for healthy life both in the United States and increasingly everywhere in the world: the constant and inescapable promotion of unhealthy meals and sugar-filled beverages. the absence of secure spaces for exercise. the fast meal offered at the neighbourhood store, at work, and at school. When you add it all up, it becomes difficult for people to make the healthy decisions that are crucial to a high quality of life and a healthy weight.
