Abstract

The researcher observes recently  that the individual has become rapidly tired and stressed, and many healthy and natural physical characteristics have changed,  postural deviations have increased and spread , and  body resistance to diseases has decreased , and a person shifted from practice to viewing, so obesity and flabbiness increased as a result of the lack of daily physical activities.                                          

Fats are the most likely component of the body to increase or decrease, and most of their increases or decreases in the body are caused by the nutritional imbalance between the number of calories entering the body through foodstuffs and the number of calories consumed through vital life and sports activity, .Therefore, it is imperative to take all measures to combat weight gain and the percentage of body fat because of this importance in avoiding the health problems that are associated with these two factors, which are considered health risk factors.
