Dr. Ben House, PhD. is a Nutritionist (CN), Functional Diagnostic Nutrition (FDN) practitioner, and Certified Functional Medicine Practitioner (CFMP), as well as a strength coach and the owner of Functional Medicine Costa Rica. He has a passion for researching, writing, and teaching, and hosts professional and wellness retreats in the Jungle of Uvita, Costa Rica.

Today Ben is talking with Dr. Tommy Wood, MD, PhD, about his pragmatic approach to health coaching and training. They discuss testosterone, estrogen, ketosis, and building strength, muscle mass and resilience. They also share problem-solving strategies for helping clients who aren't making the progress they want.

In the intro, I also mentioned our new Blood Chemistry Calculator that utilizes a machine learning algorithm and blood chemistry data from 36,000 people. This is a powerful tool that can help identify your specific health challenges without directly testing for them, pointing you more squarely in the direction of your health and performance goals.
