I'm just wondering what people think is a safe amount of dark chocolate to eat. I bought a 100% bar with no sugar, but to be honest I felt like spitting it out. I've bought a different one 90% with a bit of sugar. Looking at the back 100g with 10 pieces has about 15g of carbs of which 7g is sugar and about 600kcal. So I'm thinking one piece is about 60kcal which seems a lot, so maybe half a piece might be safe at 30kcal?
