Are You Addicted to Eating?

According to the World Health Organization (WHO), worldwide obesity has nearly doubled since 1980. Researchers have discovered that the most startling cause for the increasing obesity epidemic is diet induced addiction to foods. Scientists have discovered that certain highly palatable foods disrupt the smooth functioning of the same brain-reward-pathways as cocaine and heroin. Overeating affects many of the bodies systems.  Functional MRI scans performed on two patients with congenital deficiencies of the food satiety signal (Leptin) revealed the fundamental role this food signaling hormone plays in switching off the desire for food. The word Leptin is derived from the Greek word (Leptos) which means thin. Leptin is released after meals to enhance the satiety signals that diminish perception for food. Researchers have discovered that hormones like Leptin are altered in obese patients and thus they are less responsive to its signaling capacity. Food is the life bridge for our well-being, and what we intake for the normal functioning of our bodies really needs to be examined if we’re going avoid the deleterious effects of overeating.
