Increase in physical activity is also linked to a parallel improvement in diet quality, according to researchers at the Harvard University.
Exercising increases gray matter and pre-frontal connections in the brain, which in turn brings on 'inhibitory control'. Exercise makes people more aware about their own bodies. Active people realize they are full sooner and stop eating sooner than inactive people.
Lead researcher Miguel Alonso Alonso said, "Physical exercise seems to encourage a healthy diet. In fact, when exercise is added to a weight loss diet, treatment of obesity is more successful and the diet is adhered to in the long run."
The study helps us understand the interaction between exercise and a healthy diet. This could improve preventative and therapeutic measures against obesity by strengthening current approaches and treatments.
