PI2 (Slendesta) from potatoes may help curb our appetite

Nov 07, 2011

The ingredient from potatoes known as proteinase inhibitor 2 (PI2) with the trade name of Slendesta has been proven to increase the level of CCK if taken an hour before meals. CCK stands for Cholecystokinin. It is a hormone that triggers particular events when released; the digestion of food and the suppression of hunger.

Lean men were split into three groups and were fed a lunchtime meal. One group was fed the lunchtime meal only. A second group were fed the same meal but this time with a bowl of soup 5 minutes before and this addition of the soup decreased the amount of food eaten (as calories) by 3%. The third group was also fed the same lunchtime meal preceded 5 minutes before with the same soup but this time they had PI2 added to the soup. Adding PI2 cut the intake of food calories from the same lunchtime meal by 17.5%. The study was performed at the University of Leeds in the UK and is published in the journal Physiology and Behavior.
