We've all been told that to lose weight you need to eat less and move more. In many cases, it is not as simple as calories in vs calories out. Some women are eating very little and continue to gain weight. Some are working out very hard and feel like they have nothing to show for it. In many cases, hormones play a role in finding a healthy body weight. The one I come across most frequently in my work with athletes is cortisol. Cortisol plays an important role in the body.
