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.

Different studies have assessed the influence of chewing gum to aid control of appetite and reduce food intake.The aims of the present study were to evaluate the effects of chewing gum on satiety, food hedonics and snack intake and to explore the potential effects of the combination of Garcinia c ambogia, green coffee extract and L-carnitine on satiety, when administered in a gum format.This was a prospective study in which 57 subjects randomly received three kinds of treatments, in a crossover design: (1) active gum; (2) placebo gum; and (3) no gum. Food preferences and appetite sensations were evaluated by means of the Leeds Food Preference Questionnaire and visual analog scales.There was a significant reduction in low-fat sweet snack intake with placebo gum and the active gum compared to no gum and a reduction in high-fat sweet snack intake with the active gum compared to placebo gum and no gum. Total caloric intake was only reduced in the active gum condition. Both the active and placebo gum conditions significantly reduced hunger and prospective food consumption and increased fullness compared to no gum and were associated with a reduced wanting for sweet food in the LFPQ, consistent in a reduction in the relative preference for sweet snacks versus savoury snacks.This study supports the notion that chewing gum containing nutraceutical products might aid in the control over snack intake and reduce hunger sensations.
