i'm on a diet

I think a piece of some sweetness and sugar is good for once in a while. After all, you even need the sugar and also a bit fat, for example in the winter, since fat will be turned into something that keeps your body warm in cold places. As long as it was a little bit it just doesn't matter. As no one ever tells you but everything should be eaten in little portions, a little of this and a little of that spread out over weeks or months.
