Food For Your Thoughts!

(Ivanhoe Newswire) -- Here's a new reason to hit the gym. Besides burning calories, it also makes you think you're fuller.

New research shows exercise restores the sensitivity of neurons involved in the control of satiety or feeling full, which in turn contributes to reduced food intake and consequently weight loss.

Obesity has been an increasing problem in the world. Just in the U.S, in 2009, only Colorado and the District of Columbia had a prevalence of obesity less than 20 percent. Thirty-three states had prevalence equal to or greater than 25 percent. Factors such as changing eating habits and a sedentary lifestyle both have a role in the pathogenesis of this disease.

Researchers at the University of Campinas, Brazil, demonstrated that exercising obese rodents showed signals of restored satiety in hypothalamic neurons and decreased food intake. Physical activity has always been considered a cornerstone in the treatment of obesity, however, only now have the effects of exercise on the control of body weight been understood.

These findings, besides reinforcing the necessity for regular exercise also change the current paradigm established between physical activity and weight loss.
