NCT04991714

Brief Summary

The aim of the present study is to investigate the influence of the modulation of the sweetness intensity of a carbohydrate (sucrose)-containing solution on metabolic effects, in particular the regulation of blood glucose concentration and regulation of hunger \& satiety.
