Diets in Type 1 Diabetes Study Research | Overview

 

A clinical trial conducted at Boston Children's Hospital currently recruiting participants with type 1 diabetes.

The Diets in Diabetes Study

We are studying how the carbohydrate content of the diet affects blood glucose control and brain function in patients with Type 1 Diabetes.

  • Are you between the ages of 18 and 40?
  • Have you had type 1 diabetes for at least one year?
  • Are you using a continuous glucose monitor (CGM) and insulin pump?
  • Is your hemoglobin A1c (HbA1c) between 6.5 and 9 percent?

If you answered "yes" to all the questions, you may be eligible to participate in the Diets in Diabetes Study.

The study involves:

  • Consuming foods given to you by the study team for 12 weeks. Study meals will be delivered to your home by a company specializing in food delivery. You will be randomly assigned to receive one of two different diets: the standard carbohydrate diet, which follows routine dietary recommendations for diabetes, or the very low carbohydrate (ketogenic) diet, which provides a reduced amount of carbohydrate.
  • Up to five weekday in-person study visits at Boston Children’s Hospital or Beth Israel Deaconess Medical Center over the course of 12 weeks. Most visits take about one to two hours, and some involve a blood draw.
  • Two of the visits take longer, about four to five hours, and involve IV placements, frequent blood draws, and a glucagon injection or MRI studies of your brain during hypoglycemia (low blood sugar). One of these visits may include a ketone drink.

You will receive:

  • free home delivery of all your meals for 12 weeks
  • intensive diabetes management and medical supervision
  • free parking or travel reimbursement for the study visits and compensation up to $1,300.

Eligibility criteria include:

  • age 18 to 40
  • type 1 diabetes for at least one year
  • BMI between 18.5-35 kg/m2
  • stable glycemic control (HbA1c = 6.5-9 percent)
  • current use of a CGM and insulin pump
  • attendance of at least one diabetes care visit with your diabetes doctor and/or diabetes nurse educator in the past year (including virtual)
  • For more details on who can participate in the study, see the "who is eligible?" section on the study details page.
