Nutrition and Type 1 Diabetes: What Are Best Practices for Insulin Dosing?
I recently had the opportunity to contribute to an upcoming text from the American Diabetes Association on nutrition therapy in diabetes care.

I recently revisited Lingo, Abbott’s direct-to-consumer continuous glucose monitoring (CGM) system, after a new wave of clients began seeking guidance on how to use it to support metabolic health, including diabetes prevention, insulin resistance, and weight loss.
