All chocolate will still contain calories and binge eating isn’t healthy but if you are aiming for less sugar, the darker the chocolate the better it is.
A 100g bar of milk chocolate contains about 530kcal – roughly a quarter of your total recommended calories for the day. If you switched that for a bar of 90 per cent cocoa dark chocolate, you wouldn’t save any calories, but dark chocolate does have 75 per cent less sugar than milk chocolate.
Binging is not a healthy way to eat, but the lower sugar and more intense taste of dark chocolate makes it less likely that you will feel the same craving to eat it in large quantities. White chocolate is the worst – it has more calories than milk chocolate and more sugar than dark.
