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.
