Complementary foods for appetite suppression

Abstract

New diet strategies are needed to aid with weight loss and adherence to energy‐restricted diets. This study examined the appetite suppression and antiglycemic effects of two novel foods: algae and gelatin. In a double‐blind, randomized, crossover study, 15 healthy individuals (7 M, 8 F; 28±7y, BMI 26.1±5.6kg/m2) consumed an isocaloric breakfast meal under three treatments separated by 1–2 wk: control (buttered bagel, juice); algae (algae [4g protein] enriched butter, bagel, juice); and gelatin (gelatin [4g protein] enriched butter, bagel, juice). Five blood samples (0, 30, 60, 90, 120 min postprandial) were collected and analyzed for glucose. Hunger was assessed using a 100mm visual analog scale. Food and beverage consumption for the remainder of the day was recorded. Neither algae nor gelatin altered postprandial glycemia or perceptions of hunger up to 2 h post‐ingestion. However, there was a marked decrease (300–400 kcal) in subsequent 24 h energy consumption in the gelatin group when compared to the algae (p=0.01) or control (p=0.07) groups. These data suggest that gelatin ingestion may be associated with appetite suppression over a 24 h period.
