James LeCheminant, PhD, and associate professor of exercise sciences at Brigham Young University in Provo, Utah, did a study of 35 women who had brain scans to figure out how their brains responded to pictures of food.  One group of scans was done after the women walked briskly on a treadmill for 45 minutes.  A second study was completed of their brains without having the women exercise first.  LeCheminant's study found that when the women had just exercised, the brain responses to the pictures of food, which were considered a marker of appetite, were reduced.  Dieting to control your weight can be difficult if you are not exercising.  Reduce your desire to eat by doing moderate exercise.  And remember, a hypnotherapy session can be a great motivator to get moving!
