568 Kara Collier- Constant Glucose Monitor: EVERYTHING you want to know

·1 hr 19 min·5 clips

Kara Collier reveals why hospital diabetic meal plans are so bad they should be thrown away.

This episode features Kara Collier, co-founder of NutriSense and a Forbes 30 Under 30 honoree, discussing continuous glucose monitors (CGMs) with host Eddie. Collier is a registered dietitian and certified nutrition specialist who previously worked in hospital ICUs. She explains that CGMs were originally FDA-approved medical devices for type 1 and later type 2 diabetics. Collier describes the CGM insertion process as involving a painless, momentary needle that places a microfilament under the skin on the back of the arm. She states optimal fasting glucose should stay under 90 mg/dL, while post-meal spikes should remain below 140 mg/dL and return to baseline within two hours. Collier shares that her frustration with hospital food systems, like serving sugary sodas on patient trays, motivated her to found NutriSense. She reveals research indicates an average glucose level below 105 mg/dL correlates with a hemoglobin A1C around 5.2-5.4%. A key behavioral insight is the "protein first" rule, where eating protein before carbohydrates in a meal can significantly improve the glucose response. Eddie recounts his own experiment eating only McDonald's for 30 days by removing buns and sauces, which resulted in improved metabolic markers. Collier emphasizes that 90% of chronic conditions leading to hospitalizations are preventable, linking metabolic health as a root cause. A surprising claim is that the official "non-diabetic" fasting glucose threshold of under 100 mg/dL may not be optimal, with under 90 being a better target. Collier notes that people are increasingly proactive, seeking interventions when their A1C is near the pre-diabetic threshold of 5.7% rather than waiting. The conversation critiques institutional food, from hospital meals to school lunches, highlighting systemic barriers to change. Eddie's personal story of childhood sugar crashes illustrates the direct impact of diet on energy and focus. The tone is conversational and educational, blending personal anecdotes with practical data. Listeners interested in biohacking, nutrition, and preventive health will find this episode valuable, while those averse to discussions of blood sugar metrics or dietary restriction may want to skip it.

As heard by us

A lively CGM conversation that makes blood sugar feel practical, not mystical.

Continuous glucose monitors give this WODcast a strong hook, especially as Eddie starts from his own uneasy but curious A1C check and turns it into a personal experiment in fitness-world health tracking.

Why you'd press play

You want a CGM conversation that starts with bloodwork and a slightly high A1C, not abstract theory.
