Grazing. Chronic stress. Poor sleep. Rushed meals. Sitting for long hours. Underfueled workouts. Estrogen decline. There’s a lot more behind our fasting glucose and A1C than how many carbs we eat. This week we return to one of the most consistently requested topics: blood sugar meaning and management with Liz McKinney, CNS, LDN. We explore what glucose spikes really mean, why time-in-range and variability matter more than a single peak, and how stress, sleep, and even eating speed affect your numbers. We cover carb timing, meal sequencing, post-meal walks, creatine, why under-fueling can make exercise spikes worse, and much more so you can keep glucose working for your performance and overall health.

Liz McKinney, CNS, LDN, heads up the clinical nutrition team at Nutrisense. Liz holds a Master of Science degree in Clinical Nutrition and Integrative Health and is a board-certified nutrition specialist (CNS) as well as a licensed dietitian nutritionist (LDN). In her time as a nutritionist, Liz has educated and counseled hundreds of clients in areas such as weight loss, hormonal imbalances, and gastrointestinal diseases. Her approach is rooted in the tenets of functional medicine, and she strives to identify the root cause of the issue instead of simply treating the symptoms. She realizes there is no one-size-fits-all approach to achieving optimal health and feels it is crucial to be in an equal partnership with her clients.
