Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present study was to compare the effects of three different dietary patterns on glycemia in individuals with type 1 diabetes (T1D).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of the present crossover study was to compare the effects of three different dietary patterns on glycemia in individuals with type 1 diabetes (T1D).

Three different isocaloric diets, namely, a Mediterranean style diet, a low-carbohydrate diet and a reference diet were provided to patients with T1D for three separate weeks, in a random order, and with 7-day washout periods in-between. Glycemia was assessed during each 7-day period using a continuous glucose monitoring system. Participants were recruited from the outpatient diabetes clinic of a University Hospital in Athens, Greece.

The primary outcome was time spent in euglycaemic range (TIR: 70-140mg/dl) during the diet period. Secondary outcomes were: (a) time spent below euglycaemic range (TBR: \<70mg/dl); (b) time spent above euglycaemic range (TAR: \>140mg/dl); (c) glycaemic variability and (d) insulin needs.
