Brief summary
The objective of the study is to establish whether a Pineapple juice with Viscofiber and Red ginseng can enhance satiety and reduce appetite and/or accelerate satiation in the short-term.
Detailed description
A double-blind, randomised crossover design will be employed with an experimental (active) condition and a control condition at least one week apart. After having successfully completed screening procedures eligible participants will be invited for two separate test days, at least 7 days apart. On the two test days, the products will be provided in a randomized order as part of a fixed breakfast meal, and subjective appetite ratings will be measured every 30 min for the following 8 hours. Satiety and satiation will be measured through administration of test meals in the laboratory supplied with controlled food intake under free-living conditions
