Food and Function

A nutraceutical product composed of a combination of Garcinia cambogia, l-carnitine and a seaweed extract of Ascophyllum nodosum has been recently developed. The aim of the present study was to characterize its effects on subjective satiety sensations and food preferences in healthy volunteers. In a crossover design, 28 subjects (21 females and 7 males, aged 31 ± 5, BMI 22.6 ± 1.7) were randomly assigned to receive the active treatment (LIS) or placebo (PL) over one week. At the end of each treatment period, subjects were instructed to consume ad libitum a test meal. Food preferences and appetite sensations were evaluated by means of the Leeds Food Preferences Questionnaire and visual analog scales, before and after meal, over three hours. There were no differences in energy intake between study groups. LIS was associated with a reduction in subjective hunger sensations (p = 0.018) and to an increase in satiety (p = 0.02) and fullness (p = 0.01) ratings. The preference for high fat foods was reduced after consuming the test meal in both study groups. There was a significant effect of LIS treatment on food explicit liking and implicit wanting, as evidenced by an increase in preference for sweet foods (relative to savory foods; p = 0.03 and p = 0.004, respectively), but no differences were observed regarding the preference for low or high fat foods (NS). These results provide proof of principle for the satiating properties of a nutraceutical containing Garcinia cambogia, Ascophyllum nodosum extract and l-carnitine and suggest that it might be useful as an appetite modulator.
