There are several scientific organizations such as World Health Organization and International Obesity Task Force that have been working on the causes, symptoms and treatment of obesity and its related diseases. These organizations have calculated reference values for Obesity and Overweight. According to the results obtained, there was a difference among these values. The IOTF values were shown to be more conservative than that of the WHO values. A significant difference of 4-6% has been found among these values. The results concluded that caution has to be maintained while collecting weight data from a population. Various Health care professionals are also working in the societies in order to give counseling and training programs for eradication of obesity and related disorders from the society. However, it has been seen that these health care individuals, who are expected to be the ideal persons for the obese individuals have also been seen to gain weight. This has a strong impact on the society. Healthier Health care professionals will be a way of encouragement towards the diseased individuals.
