Usually, obese individuals go on various diets in the ambition to lose weight, most with the typical reasons of looking better, feeling better and most importantly, being healthier, as obesity has been known to cause many health problems and heighten the chances of getting certain sicknesses and diseases; such as an increased risk of potentially fatal health problems such as heart attacks, high blood pressure and diabetes. However, several studies have shown that many misguided dieting methods are actually harmful to health; which is highly ironic, taking that most go on diets to improve their own health.
An example of a harmful dieting effect is known as the "yo-yo effect", in which an individual constantly loses weight and puts them back on. Doctors say that repeated change in body weight eventually puts additional stress on the heat and leads to other health problems; in which dieters put themselves in the risk of a heart attack. Among the potential ailments stemming from repeated weight loss and regain are cardiovascular disease, stroke, diabetes and altered immune function. Further more, the dieters who lose the weight initially are found not only to gave gained back the pounds and kilograms, but have ironically been shown to gain more, defeating the purpose of a diet.
Researchers have concluded that for many individuals, it would have been healthier for them not to have tried to lose weight by dieting at all. Exercise, on the other hand, appears to have been more helpful. Researchers identified exercise as a key researcher leading to sustained weight loss. Studies consistently find that dieters who exercised the most also had the most weight loss.
The "yo yo effect" is caused by "yo yo dieting", a diet, or rather, diets in which obese individuals resort to highly extreme ways to lose weight, often with the typical and highly upsetting and discouraging result: initial loss of weight, then regaining of the initial weight loss and even more weight later on. This is as many dieters look for quick fixes to their weight problems, either by starving themselves or by going on fad diets. However, as soon as they revert to their unhealthy eating habits, the weight is regained in full force; bringing along with it many health risks and problems which may be potentially fatal.
Therefore, it can be seen that the typical yet highly successful dieting method of adequate exercise and a healthy diet is the best way to shed the pounds and kilograms; quick fixes and fad diets are not the way to go.
