Effect of Kefir on Appetite

Effect of Kefir on Appetite

This study aimed to determine the effect of kefir on appetite in healthy subjects. A randomized, single-blind, and 3-intervention crossover trial included 22 healthy and normal-weight (BMI 18.5-25 kg/m2) females aged 21-24 years. Participants were recruited to three test meals: an LGI-Milk, an LGI-Kefir, and an HGI-Kefir, with a one-week washout period. Appetite ratings were measured at 0, 15, 30, 60, 90, 120, 150, and 180 minutes. At the end of three hours, participants were served an ad libitum lunch meal. Then, the foods eaten at lunch were recorded and their energy and nutrient analysis was calculated.
