OBJECTIVE: A combination of bioactive food ingredients (capsaicinoids,
epigallocatechin gallate, piperin, and l-carnitine, CBFI) may promote satiety and
thermogenesis. The study was conducted in order to assess whether there is any
effect on satiety, resting energy expenditure (REE), respiratory quotient,
glucagon-like peptide-1 (GLP-1), free fatty acids (FFA) and glycerol release,
following a standardized mixed meal with or without single consumption of a CBFI.
DESIGN: An 8-week randomized double-blind placebo-controlled trial.
SETTING: Dietetic and Metabolic Unit, Azienda di Servizi alla Persona, University
of Pavia and "Villa delle Querce" Clinical Rehabilitation Institute, Rome, Italy.
PARTICIPANTS: Thirty-seven overweight adults (body mass index [BMI]: 25-35).
INTERVENTION: Nineteen overweight subjects were included in the supplemented
group (14 women, 5 men; age 46.4 ± 6.4; BMI: 30.5 ± 3.3) and 18 in the placebo
group (13 women, 5 men; age 40.8 ± 11.5; BMI: 30.1 ± 2.6). Satiety was assessed
using 100-mm visual analogue scales (VAS) and the area under the curve was
calculated.
RESULTS: All measured parameters increased significantly in comparison with
baseline in response to meal, both with CBFI and with placebo. However,
throughout the study day, the supplemented group experienced a significantly
greater increase than the placebo group in their sensation of satiety following
acute administration of the supplement.
CONCLUSION: CBFI may therefore be of great value in the treatment of overweight
patients by increasing satiety and stimulating thermogenesis.
