Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is ad libitum energy intake of an ad libitum test meal served 30 minutes after start of the oral exposure/ intragastric infusion. To measure energy intake, the amount of provided food will be determined, as well as the leftovers. Chemical analyses will be performed to determine the exact energy and macronutrient content of the lunch. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes measures are - subjective feelings of satiety that are measured via Visual Analogue Scale ratings. Hunger, fullness, prospective consumption, desire to eat, desire to eat something sweet, desire to eat something savoury, thirst, wellbeing and nauseous feelings will be rated. - gastric emptying rate will be measured with a non-invasive breath test. The gastric load which the subjects receive for the gastric stimulation will be labeled with a stable isotope: 13-C acetate. After some time part of the 13-C acetate will be present in the breath of the subjects. During a test day, 7 breath samples will be collected of a subject. The rate of gastric emptying will be determined by measuring the 13-C isotopic enrichmen in the collected breath samples. Gastric emptying rate of 1min/800ml treatment The gastric emptying rate of the 1min/800ml treatment will be compared to the control, to see whether it is significantly quicker. That might be the reason that we did not found a significant effect of gastric filling volume on ad libitum energy intake in our previous study. | — |
