2. Personally, except for 100% chocolate, it is really not easy to get fat. According to different ingredients, there are different degrees of weight gain risk. But the concentration of 72% is really much better than milk chocolate!
The real focus is how much chocolate you ate:
Personally, I eat chocolate almost every day (but the boss who sells chocolate cries. . . ) So my classmates said they didn't see me gain weight.
If you only take it occasionally (not in large doses), don't care about this problem. If you don't want to gain weight, don't believe some gimmicks that won't gain weight.
Bottom line: eat in small quantities (I have a look, a box is about 135g, so I will finish it within one week).
