Meet the Hosts


Rachel Scheer

Rachel Scheer is a Functional Medicine Nutritionist who received her degree from Baylor University in Nutrition Science and Dietetics and became certified in functional medicine through the Kalish Institute.

Rachel's journey as a nutritionist began in bodybuilding and athletic performance, however, a couple years into her practice she began to suffer from severe gastrointestinal dysfunction (IBS.) After many false diagnoses, spending thousands of dollars on doctor visits and tests, and one doctor even suggesting the removal of her entire large intestine, Rachel decided to take her health into her own hands.

Rachel says "using a functional approach and focusing on the health of the gut microbiome saved [her] life. All disease begins and ends in the gut, so rather than putting a 'band-aid' over an issue I.e. medications/drugs/surgery, we need to get to the root cause and that's what functional medicine comes in. My gut issues came from a bacteria imbalance or gut dysbiosis, and once I was able to address that through diet, stress, supplements, and lifestyle changes I was able to heal my body, avoid surgery, and come off dozens of medications I was put on over the years."
