Time-restricted eating in pregnancy
Time-restricted eating in pregnancy
Time-restricted eating is a dietary strategy in which you limit the daily time-window for energy intake, typically to 8-10 hours. Such an eating pattern has shown benefits for individuals who are at risk of developing diabetes. We are assessing whether time-restricted eating is feasible for pregnant women who have increased risk of gestational diabetes, and whether it can improve glucose control.
Half of the participants in this study is asked to limit their daily time-window for energy intake to maximum 10 hours for 5 weeks. All participants are recommended to follow the nutritional guidelines for pregnant women from the Norwegian Directorate of Health.
Criteria for participation
- 18 years or more and in gestational week 12-30
- Habitual daily eating window of 12 hours or more
- At least one of these criteria must be fulfilled: BMI of 25 kg/m2 or more (pre-pregnancy)/more than 25 years old and expecting the first child/previous gestational diabetes/previous child with birthweight of more than 4.5 kg/Asian or African origin.
The participants will undergo blood sampling, including an oral glucose tolerance test, measurements of blood pressure, and body composition. All participants will additionally wear a continuous glucose monitor. The study is undertaken at the Faculty of Medicine and Health Sciences, NTNU, in collaboration with the Women’s Clinic at St. Olavs hospital, and is approved by the Regional Committee for Medical and Health Research.
