Obesity is a complex disease involving an excessive amount of body fat. Obesity isn't just a cosmetic concern. It's a medical problem that increases the risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure and certain cancers.If a person does have obesity, it can increase their risk of developing a number of other health conditions, including metabolic syndrome, arthritis, and some types of cancer.Metabolic syndrome itself involves a collection of conditions, including high blood pressure, type 2 diabetes, and cardiovascular disease.Maintaining a moderate weight or losing weight through diet and exercise can help prevent or reduce obesity. In some cases, however, a person may need surgery.
Some processed food products, such as ketchup, contain high fructose corn syrup as a sweetener.Eating too much of these foods and doing too little exercise can result in weight gain and obesity.
The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended. Globally, there has been:
•an increased intake of energy-dense foods that are high in fat and sugars; and
•an increase in physical inactivity due to the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization.
Obesity is a leading preventable cause of death worldwide, with increasing rates in adults and children. In 2015, 600 million adults (12%) and 100 million children were obese in 195 countries.Obesity is more common in women than in men. Today, obesity is stigmatized in most of the world. Conversely, some cultures, past and present, have a favorable view of obesity, seeing it as a symbol of wealth and fertility.Nevertheless, in 2013, several medical societies, including the American Medical Association and the American Heart Association, classified obesity as a disease.
People with diets that consist mainly of fruits, vegetables, whole grains, and water are still at risk of gaining excess weight if they overeat or if genetic factors increase their risk.
However, they are more likely to enjoy a varied diet while maintaining a moderate weight. Fresh foods and whole grains contain fiber, which can encourage healthy digestion and help a person feel full for longer.
