Glycemic Variability in Intermittent Fasting

Overview

The aim was to test the difference in glycemic variability after meal consumption during intermittent fasting and the usual diet.

Healthy participants were recruited for this crossover study aiming to determine the difference in glycemic variability after meal consumption while practicing intermittent fasting and the usual diet. Prior to the protocol assignment, participants were followed for 3 days - they were instructed to maintain their usual sleep pattern, level of physical activity and diet. Control of dietary pattern was conducted by using the 3-day food diary. Day zero was preparation day for the protocol (Intermittent fasting or Control diet) when all participants received individualized 3-day diet plan. Each protocol lasted 3 days with a 7-day washout period. Each protocol consisted of 3 meals per day, each providing a third of the total energy requirement. Control diet protocol was set at 12 hours eating/12 hours fasting, and Intermittent fasting protocol 6 hours eating/18 hours fasting. Blood glucose was measured at zero, 15, 30, 45 and 90 minutes after meal consumption. Before breakfast, blood glucose was measured also at minus 5 minutes prior meal consumption.
