Fixing Diabetes At The Cellular Level with Dr Jason Shumard

Send us Fan Mail

Most advice for type 2 diabetes starts and ends with “lower your blood sugar.” That sounds logical, until you realize blood sugar can be the smoke, not the fire. Joe Grombine sits down with functional medicine practitioner Dr. Jason Shumard to unpack a different model of insulin resistance and metabolic health, one that focuses on why your cells stop handling fuel well in the first place.

We break down diabetes in plain language: how glucose is supposed to move from food to bloodstream to cells, why insulin is the key, and how chronically high insulin can drive cellular damage over years. Dr. Shumard explains why diabetes gets labeled “progressive,” why an A1C can look “managed” while complications still build, and why the term “pre-diabetes” can be misleading if it makes you think nothing is happening yet. You’ll also hear how diet matters, but why diet alone may not fix a broken foundation.

From there, we zoom out to the root causes that keep metabolism stuck: fatty liver or liver congestion, systemic inflammation, gut health issues like dysbiosis and leaky gut, adrenal stress, thyroid dysfunction, autoimmune patterns, infections, and toxin exposures. The big theme is smarter precision: comprehensive lab testing, prioritized problem-solving, and a plan built around your biology instead of generic rules. Dr. Schumard also shares how his telehealth practice works across all 50 states and where to find his free webinar at drshumard.com.
