Vitamins and minerals being non caloric molecules do not really have any impact on the caloric weight of a meal. However, we can say that vegetables, which often come with high amounts of vitamins, are not an important source of calories, most of the time. Avocados, for instance, are more caloric, nut are also a more important source of fat. We can say for sure that foods with fat and sugars are inevitably high in calories, because those molecules (glucose and lipids) can be converted into a lot of energy.
