A study from the German Research Center for Food Chemistry found that even just smelling EVOO may lead to greater feelings of fullness. When an aromatic extract was added to yogurt, participants consumed fewer calories and had a better blood sugar response compared to those who were given plain yogurt without any added extracts.
