Primary Outcome Measures

Name	Time	Method
The main outcome parameter in this study is the composite satiety score (CSS), measured from baseline until 120 minutes after starting the consumption of the study product: <br>-Area under the curve (AUC; score x minutes)<br>-Incremental area under the curve (iAUC; score x minutes) <br>-Absolute values (score) at baseline (-5 minutes) and 15, 30, 45, 60, 90 and 120 minutes after starting the consumption of the study product <br>-Change from baseline (score) at 15, 30, 45, 60, 90 and 120 minutes after starting the consumption of the study product <br><br>The CSS will be calculated through the equation (satiety + fullness + (100 – hunger) + (100 – prospective food consumption))/ 4. Satiety, fullness, hunger and prospective food consumption will be assessed on a VAS, with scores ranging from 0 to 100. The CSS also ranges from 0 to 100.

Secondary Outcome Measures

Name	Time	Method
Other outcome parameters in this study are:<br>-Satiety, fullness, hunger, prospective food consumption measured from baseline until 120 minutes after starting the consumption of the study product<br>-AUC (score x minutes)<br>-iAUC (score x minutes)<br>-Absolute values (score) at baseline (-5 minutes) and 15, 30, 45, 60, 90 and 120 minutes after starting the consumption of the study product<br>-Change from baseline (score) at 15, 30, 45, 60, 90 and 120 minutes after starting the consumption of the study product<br>-Adherence to use of the study product, defined as volume consumed within 15 minutes relative to 1 serving (%)<br>-Overall liking of the study product (score), assessed 15 minutes after starting the consumption of the study product on a liking scale ranging from 1 to 10.
