Abstract

The objective of this study was to investigate the efficacy of lipid emulsions encapsulated in calcium-alginate beads in reducing food intake and appetite sensations. These emulsion-alginate beads were ingested in a yogurt (active) and compared to an equienergetic yogurt containing nonencapsulated nutrients with comparable sensory properties (control) in a randomized placebo-controlled trial with crossover design. Thirty-three healthy overweight volunteers (mean age: 43 years; body mass index: 27.7 kg/m2; 14 male) received the 2 treatments. Test days started with a standardized small breakfast (t = 0) followed by an active or control yogurt (t = 90 minutes). Appetite sensations and gastrointestinal symptoms were monitored prior to and after consumption of the yogurt, and food intake was measured during ad libitum pasta meal consumption (t = 210 minutes). The hypothesis for this study was that delayed release of encapsulated lipids suppresses appetite sensations and reduces food intake. Food intake was significantly reduced with 51 ± 20 kcal (213 ± 84 kJ) (P =.016) after intake of the active yogurt (770 ± 38 kcal (3222 ± 159 kJ)) compared to the control (821 ± 40 kcal (3435 ± 167 kJ)). The approach that we chose is promising to reduce food intake and could contribute to the development of an easy-to-use product for weight management.
