Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health, leading to lower life expectancy. The worldwide prevalence of obesity has nearly doubled since 1980. According to the outcome of Saudi Health Interview Survey (SHIS) 2013 conducted by the Ministry of Health (MOH), the rate of obesity in Saudi Arabia hit 28.7%, while the rate of weight gain recorded 30.7% in the age group of 15 years and above. The weight gain and obesity is caused by the imbalance between your energy input (the calories you consume) and energy output (the calories you burn).
