“Obesity is not a personal choice. It is a complex interplay of genetics, environment, and other factors. The magnitude of this disorder’s impact on health can be understood when we realize that obesity impacts 236 diseases, of which 13 are cancers.” (Obesity Medicine Association) Genetic factors that include thousands of different genes contribute to 40 to 70 percent of obesity.
The World Health Organization (WHO) defines obesity as “abnormal or excessive fat accumulation that presents a health risk.” World Obesity Organization puts obesity as one of the most critical public health problems facing the world today.
Three factors are externally responsible for obesity and obesity control. These are:
Nutrition: Certain foods, such as refined carbohydrates and unsaturated fats, contribute the most to obesity
Medicine: Certain prescription medicine, including anti-depressants, steroids, contraceptives, medications for diabetes, hypertension, migraines, seizures, bipolar disorder, allergies, insomnia, and a host of others, are associated with weight gain.
Sleep: Disrupted sleep or sleep less than 7 hours or more than 9 hours can lead to obesity. Difficulty in breathing can also be a reason for disturbed sleep.
Given the complexity of this disorder, there are no simple definitions nor simple cures to this condition.
