Several epidemiological, pathophysiological and clinical studies reveal that obesity and overweight conditions are the two major factors contributing to the risk of cardiovascular diseases. Obesity is now a world-wide epidemic, more pronounced in USA, Europe and all other developing nations. Obesity/ overweight is due to the imbalance between physical activity and dietary energy intake. Sedentary life style, unhealthy diet and consequent overweight and obesity markedly increase/worsen the risk of cardiovascular disease.

By now, it is an admitted fact that obesity causes insulin resistance and diabetes. The evidence linking early stages of Glucose dysregulation with cardiovascular diseases, needs a serious consideration. Overweight / obesity raise the heart rate and reduce the body's ability to transport blood through vessels.

Aggressive treatment of subjects with impaired fasting glucose or impaired glucose tolerance have the potential to reduce both the incidence of diabetes and its related cardiovascular disease. Another research study ( Ref: Health ramification of the obesity epidemic- Li. z.Bowerman S and Heber D. ) indicates that obesity and overweight related to health problems including prediabetes and diabetes and the metabolic syndrome, musculoskeletal disorders, cardiovascular disease, pulmonary disorders and certain forms of cancers. Obesity and overweight conditions account for a significant percentage of overall health care costs and significantly contribute to morbidity and mortality in USA and all around the globe.

Another research study on Nutrition and cardiovascular mortality states that about 17 million persons die in cardiovascular disease yearly in the world. Most part of this disease can be prevented by the elimination of primary risk factors, thus by the abolishment of unhealthy nutrition, physical inactivity and by the absence of smoking. The cost-effective national program, as well as the lifemode with decreasing individual risk factors can give a trend to decrease the cardiovascular mortality. Individually the usual blood pressure and cholesterol control, the inhibition of obesity and the lifemode without smoking are able to decrease the organic changes, which produce the lethal consequencies of this disease. The different kinds of diets can significantly influence the development of human diseases. The Western diet has atherogenic effect, increases the risk of myocardial infarction.

It is, therefore, a health hazard to be obese/ overweight which lead to serious health complications. Proper food habits, intake of proper and sufficient nutrition through food and food supplements, coupled with regular exercise shall lead to a healthier life. Weight loss and prevention of weight gain have to be considered as the most two important strategies to reduce the incidence of cardiovascular disease.
