title: Comparison of the effects of a liquid yogurt and chocolate bars on satiety: a multidimensional approach.
abstract: In the context of epidemic obesity, satiety is an important target for nutritional interventions. Using a multidimensional approach, we compared the effect on satiety of two food products frequently consumed in France by young adults as a small mid-afternoon meal called the 'goûter'. Participants were eighteen healthy young males (aged 20.8 (sd 1.8) years) of normal body weight (BMI 21.7 (sd 1.7) kg/m2) used to eating four times per d including a 'goûter'. On two occasions, under laboratory conditions, the time-blinded participants consumed a fixed energy lunch (2.8 MJ) and, 240 min later, either a liquid yogurt or chocolate bars matched for energy (1.2 MJ) and weight (366 g). Then, satiety was assessed by: (1) ratings of hunger, appetite, desire to eat and fullness at 20 min intervals (perception), (2) the delay until the subject requested his dinner meal (duration) and (3) energy intake at this meal (consumption). Results showed that satiety was perceived higher after liquid yogurt than chocolate bars over the 60 min preceding the next meal, as evidenced by hunger (P < 0.005), appetite, (P < 0.005), desire to eat (P < 0.04) and fullness (P < 0.05) ratings. However, its duration was similar between liquid yogurt and chocolate bars (165 (se 8) and 174 (se 7) min respectively) and this difference was not followed by reduced intake at dinner. In conclusion, this approach of satiety revealed that a liquid yogurt induced a lower subjective motivation to eat than chocolate bars during the hour preceding the spontaneous onset of a meal, without affecting subsequent food intake.
