When it comes to weight loss, most people don't think about hormones. But when you develop resistance to your seven major metabolic hormones--cortisol, thyroid, testosterone, growth hormone, leptin, insulin, and estrogen--your body adjusts by increasingly raising your hormone levels and ultimately slowing down your metabolism. And a slower metabolism leads to weight gain and difficulty losing weight. The solution, Dr. Sara Gottfried contends, is to reset the efficiency of your hormones by repairing and growing new hormone receptors. This is her proven weight loss and energy program to reverse hormone resistance in just three weeks. It will help you: Boost your metabolism and calorie burning by growing new and fresh thyroid receptors; Increase your weight loss by re-balancing estrogen and progesterone receptors; Reverse your aging by resetting glucocorticoid receptors (for better processing cortisol)
