The Venus Factor is a weight loss/exercise program developed by John Barban, a nutrition and fitness expert who believes that female resistance to the fat-burning powers of the hormone Leptin is the reason so many struggle to lose weight. His program provides online nutrition advice that steers clients away from foods that contribute to Leptin resistance and toward foods that reduce this phenomenon and according to other Venus Factor nesw live, it’s working for thousands of other women around the world. In addition, Barban has designed an exercise plan that also helps ramp up a woman’s weight loss ability.
