Outcome measures
Primary outcome
The primary study parameter is energy intake at the ad libitum lunch.
Secondary outcome
Secondary parameters are subjective feelings of satiety, gastric emptying rate, and blood glucose levels.
Background summary
It is known that some dietary fibres are beneficial for health, and some are associated with body weight management. A lot of fibre(mixtures) are not studied and their application is often limited. However, these fibres may have beneficial effects in humans, e.g. on satiety and energy intake.
Study objective
We hypothesize that in this short term study the testproducts with added fibre will increase satiety, slower gastric emptying, will give a later blood glucose peak and that it will decrease energy intake when compared to the controlproduct.
Study design
Every subject will visit the laboratory 6 times:
Once for an information and screening meeting and five times for the five testsessions. Subjects will have one testsession a week with in each session:
1. An ad libitum lunch after eating the testproduct;
2. Appetite questionnaire: At baseline and multiple times after eating the testproduct;
3. Breath sample collection: At basline and multiple times after eating the testproduct;
4. Measure of bloodglucose concentration: At baseline and multiple times after eating the testproduct.
Intervention
After a standard breakfast at home subjects will eat the testproduct (with added fibre or the controlproduct). There are 5 different testproducts: the type of testproduct (solid mueslibar/liquid yoghurt) and the dose of fibre (0 or 10g in the mueslibar and 0, 5 or 10g in the yoghurt) varies. Before each test session (baseline) and multiple times after eating the testproduct, subjects rate their appetite, blood glucose concentration will be measured and breath samples will be collected. Following this an ad libitum lunch is offered to the subjects.
