Alternating Energy Intake and Blood Fat Content After a Meal

25. August 2022 aktualisiert von: Maastricht University Medical Center

The Effect of Alternating Energy Intake Compared to Regular Energy Intake on the Fat Content in the Blood After a Meal in Abdominally Obese Adults

Increasing evidence suggests that meal timing affects metabolic health. For example, intermittent fasting (IF) may have positive effects on plasma glucose and lipid levels, insulin sensitivity, and blood pressure. However, IF protocols often result in significant weight loss. Therefore, it is not clear to what extent these beneficial metabolic effects are due to IF or to weight loss. Although the effect of IF independent of weight loss has been studied, daily energy intake in those studies did not differ between the days. Therefore, the investigators aim to examine the effect of alternating energy intake - i.e. standardised day-to-day fluctuations in energy intake - on metabolic health independent of weight loss.
