Questions about software and portals
The portal has the advantage of being variable. If you eat more of one item and less of another specific item, that is also OK. The portal can do this, unfortunately the booklet cannot.
There are 0 food items which are considered in the booklet as an arbitrary number, but when I incorporate this in a menu or change other foods, this article is also changed and suddenly goes from +++ g to 432 g. I don't understand this.
You should either use the booklet OR the portal. Both work on their own, but they are based on different principles. Thus, the comparison of the two systems is not practical or possible. The reason why it is changing from an arbitrary number to a particular weight in grams is that it is simply how the program works. If you add too many other calories, at some point it will no longer allow an arbitrary number.
