Obesity is a complex multifactorial chronic disease that develops from an interaction of social, behavioral, culture, psychological, metabolic and genetic factors. The condition of obesity is chronic, relapsing and neurochemical and involves interaction between host and environment and the need for permanent lifestyle changes supersedes the person`s desire for quick weight loss. Environmental causes of obesity are often related to overconsumption of high-fat foods, decrease in activity and smoking cessation. Obesity is an increase in body weight as the result of excessive accumulation of body fat and occurs when the calorie value of food intake exceeds energy output. Overweight and obesity is one of the preventable causes of death. Morbidity associated with overweight and obesity is also enormous. The social implication of obesity and overweight is a major problem that is often neglected. Obesity is emerging as a serious problem throughout the world, not only among adults but also children, teenagers, and young adults. Of the factors contributing to obesity, stress seems to be particularly important as stressful conditions lead to irregularity in diet, lack of exercise and addiction, each being considered an independent factor leading to obesity and the prevalence of obesity is increasing rapidly worldwide. The professional students, including medical students, are in a highrisk side when obesity is concerned. This is mainly because medical education is stressful throughout the whole course of training. The amount of material to be absorbed, social isolation, the pressure of examination, discrepancies between expectation and reality all can be anticipated to bring psychological stress. This information can be published in our peer-reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
