Intermittent Fasting Versus Carbohydrate Drinks Before Surgery

Sponsor: Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA)

View on ClinicalTrials.gov

Summary

The purpose of this study is to investigate whether time-restricted feeding, a form of intermittent fasting, before surgery improves insulin resistance around the time of surgery, compared to carbohydrate drinks and standard fasting before surgery.

Interventions

BEHAVIORAL

Time-restricted feeding

Subjects in the will be instructed to follow a TRF regimen consisting of a daily 8h ad libitum eating period and 16h water fasting period during the last 2 weeks before surgery. Participants will be encouraged to begin their eating period at 08:00h and end it at 16:00h, since the metabolic benefits of TRF appear to be considerably more pronounced when the eating period starts early in the day.

DIETARY_SUPPLEMENT

Carbohydrate loading

Subjects will continue their usual diet and will receive two quantities of a clear beverage containing 12.5 g/100 mL maltodextrin (50 kCal/100 mL, pH 5.0); 800 mL at 22.00h on the evening before surgery and 400 mL two hours before anaesthesia induction.
