The purpose of this project was to elucidate the phenomenon of elevated blood glucose in the context of dietary carbohydrate restriction. Accordingly, we sought to quantify glucagon, and related hormones, between individuals that are adhering to a low-carbohydrate diet that manifests with normal vs. elevated glucose. Moreover, we sought to test the dynamic effect of macronutrients on these same outcomes. Each participant completed 3 testing periods that included the consumption of a glucose drink, protein drink, or fat (olive oil) drink in a random order and separated by at least 2 days. Each drink was matched for volume and total calories and bloodwork was taken every 30 minutes to assess the outcomes of interest.
