Ketogenic Diet and Diabetes Demonstration Project

KDDP is a prospective, 12-month pilot study comparing the effects of the KDDP vs. CDC NDPP in patients with obesity and dysglycemia. KDDP is the Ketogenic Diet and Diabetes Demonstration Project arm. Individuals enrolled in the KDDP arm will attend a mandatory Weight Management class through the Center for Diabetes and Nutrition Education, and they will participate in a standard comprehensive lifestyle intervention program that is identical to that of the NDPP with the exception of dietary recommendations. Individuals in the KDDP arm will be educated on and follow a ketogenic diet (<20g carbohydrates/day). They will receive guidance on tracking carbohydrate intake daily, and home point-of-care ketone breath testing will be performed at regular intervals to ensure that ketosis is being achieved and maintained. They will attend weekly educational sessions facilitated by trained dieticians. Individuals enrolled in the CDC NDPP arm will adhere to a low fat diet and receive identical follow up with the dieticians relative to those enrolled in the KDDP arm. Individuals in both arms will be matched for age, sex, weight, and A1c.

Baseline measures at study entry will include weight, height, systolic and diastolic blood pressure, heart rate, hemoglobin A1c, fasting plasma glucose, total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol. These parameters will be measured every 3 months throughout the study and at study completion. Additionally, participants in both groups will be consented to undergo CAC scanning at baseline and at 12 months to assess for any differences in dietary interventions on CAC scores.
