Brief Summary

Dietary fibers likely have a role in body weight management. They may increase satiety and, as a consequence, reduce energy intake during the next meal. There are, however, many different types of dietary fiber, which have diverse physical properties and can therefore impact these outcomes differently. It is, however, unclear whether dietary fibers with different properties lead to differences in energy intake during the next meal. The objective of this study is to study the effect of pectin in 4 different physicochemical states on ad libitum energy intake and possible underlying mechanisms; i.e. gastrointestinal hormones, gastric emptying rate, feelings of satiety and the method of fiber supplementation. We hypothesize that viscous and gelling fibers will reduce ad libitum energy intake compared to low viscous and low gelling fibers.

Arm && Interventions

Group	Intervention	Description
fibre supplement	pectin supplement	high viscous, high gelling fibre is added, not to the breakfast meal, but as supplement
low viscous, low gelling	breakfast with low viscous, low gelling pectin	low viscous, low gelling fibre added to breakfast meal
high viscous, low gelling	high viscous, low gelling pectin	high viscous, low gelling fibre added to breakfast meal
low viscous, high gelling	low viscous, high gelling pectin	low viscous, high gelling fibre added to breakfast meal
high viscous, high gelling	high viscous, high gelling pectin	high viscous, high gelling fibre added to breakfast meal

Primary Outcome Measures

Name	Time	Method
energy intake	3 hours	3 hours after ingesting the test breakfast ad libitum energy intake is measured.

Secondary Outcome Measures

Name	Time	Method
appetite sensations	3 hours	appetite is measured by VAS scales over a period of 3 hours after ingestion of a test breakfast
satiety hormones	3 hours	satiety hormones (ghrelin, PYY, GLP-1, CCK) are measured over a period of 3 hours after ingestion of a test breakfast
gastric emptying rate	3 hours	gastric emptying rate is measured over a period of 3 hours after ingestion of a test breakfast
method of supplementation	3 hours	One of the fibers will be offered as tablets that will be ingested with a glass of water right after the test meal.
