When do you know if you have eaten enough and how do you ensure that you do not eat too much? Together with nutrition researcher Guido Camps (and former finalist of Heel Holland Bakt), Janny conducts an experiment that shows that you are more satiated if you eat something with structure. Janny also tests the importance of chewing, together with star chef Joris Bijdendijk.
