Understanding the fundamental science of weight management and some of the techniques for achieving and maintaining a healthy weight is very important to a person's overall health because obesity is a risk factor for many chronic disorders, like Type 2 diabetes, hypertension, and cardiovascular disease.
The prevalence of overweight and obesity are increasing in India in recent years even though under-nutrition continues to be an important public health issue even in the 21st century. Despite the availability of a few therapeutic agents, the management of obesity is still mainly non-pharmacological. Physical activity and dietary modifications are the cornerstones of the management of overweight and obesity as well as in the correction, management, and prevention of lifestyle disorders.
There are many factors that contribute to a person's weight, including diet, physical activity, genetics, environmental factors, medications, and illnesses. Each of these factors affects weight in different ways and to varying degrees, but health professionals most often stress the importance of diet and physical activity above all other factors because they can be affected by conscious behavior modification.
