Second, dark chocolate with high cocoa content is not easy to get fat, but it is not fat. As long as you pay attention to the consumption, it is best not to exceed 200 grams per week (when eating snacks) with more than 75% content, and eat less with lower content. And form a good habit of regular exercise.
Third, as to which brand is better, it depends on everyone's taste on the premise of meeting my first two points.
If you don't get fat after drinking, you can choose tea and cocoa powder (preferably sugar-free skim). Both will do.
Finally, remind the landlord that there are many sub-varieties of dark chocolate, and there is no problem in eating it properly with high content.
