In today’s What the Fitness I ask the age old question “Who invented estrogen?”. I was sent a video of Dr. Mark Hyman and my old friend Dr. Steven Gundry discussing estrogen and it’s affect on weight gain and I HAD to cover it. In this video we will look at the claims they make around estrogen and chemicals called phthalates. I will go over the research I could find on the subject and maybe have a laugh here and there. Let’s get into it!
