Brief summary
Dietary fibre seems to have a relevant role in body weight management. In an acute study the investigators found that high viscous-high gelling pectin increased feelings of satiety. The objective of this study is to study the effects of 2 weeks of supplementation of high gelling-high viscous fibre or a high gelling-high viscous non-fibre control on energy intake. The investigators do this by measuring the difference in ad libitum energy intake after 15 days of pectin or 15 days of control supplements. The investigators will further measure differences in 24h feelings of satiety, fasting blood glucose and insulin, fermentation and composition of microbiota.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Energy intake | change from placebo after 2 weeks | after 14 days of both intervention and placebo supplements ad libitum energy intake is measured for 3 days in a row. The change in energy intake will be calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| fasting glucose | change from placebo after day 0, 1 and 15 | at day 0, 1 and day 15 of supplementation period fasting glucose is measured |
| fasting insulin | change from placebo after day 0, 1 and 15 | at day 0, 1 and day 15 of supplementation period fasting insulin is measured |
| fasting leptin | change from placebo after day 0, 1 and 15 | at day 0, 1 and day 15 of supplementation period fasting leptin is measured |
| satiety | change from placebo after 1 day and 15 days | at day 1 and after 15 days of both supplement and placebo intake satiety is measured hourly over 1 day at waking hours. The change in satiety will be calculated. |
| energy intake | change from placebo after day 0 and 1 | before supplement intake and after 1 day of supplement 1-day ad libitum energy intake is measured. The change in energy intake will be calculated. |
| body weight | change from placebo after day 0,1,2,14,15, 16 and 17 | Each day the subject reports to the research center, body weight is measured. The change in body weight compared to placebo will be calculated. |
| adverse events | daily from day 0 to day 16 | participants will be asked to register adverse events daily in a diary. They are also asked to report ae's to the researchers. number and type of AEs after fibre supplements will be compared to number and type of AEs after placebo supplements |
| hydrogen in breath | change from placebo after day 2 and 15 | at day 2 and at day 15 hydrogen is measured hourly over 1 day at waking hours |
