This study aims to explore dietary factors that influence glycemic control in night shift EMS providers and to test the feasibility of a dietary intervention among these providers.

This study can be broken down into two phases. Both phases will take place over the course of 3 weeks. During the first week, participants will be scheduled for a single 60-90 minute zoom appointment. During this appointment, informed consent will be obtained, participants will provide health and demographic information, complete several questionnaires, and be familiarized with study protocols. The following week, participants will wear a continuous glucose monitor, actigraph activity monitor, document everything they have to eat and drink, and rate their daily stress levels. Participants will continue this during the final week and will be randomized to consume either a 2:1 or 1:1 protein to carbohydrate ratio during the night shift during this week.
