How many calories are in chocolate?
Quick answer

According to the German BLS food database, 100 grams (3.5 oz) of milk chocolate deliver around 535 calories. A classic 100-gram bar therefore covers roughly a quarter of an adult’s daily energy needs. The gap between dark and milk chocolate is smaller than most people assume.

Why dark chocolate is not lower in calories

Contrary to popular belief, dark chocolate is not lighter than milk chocolate. A higher cocoa percentage means more cocoa butter — and with it, more fat. As the cocoa content climbs, the sugar content does drop, but the fat share rises at the same time. At 85 percent cocoa, the calorie density actually exceeds that of milk chocolate. The real difference lies in the composition, not the calorie count.

Typical bar sizes

A single Kinder chocolate bar (12.5 g) delivers around 70 calories; a 50-gram Snickers bar comes to around 245 calories. A 40-gram (1.4 oz) portion of dark chocolate lands at roughly 215 calories — a small piece that many diets treat as "justified," yet within a daily budget it can equal the carbohydrate load of a full meal.

A meta-analysis by Tan et al. (2021) examined the effect of dark chocolate on blood pressure and endothelial function. The effects were measurable but small — and according to the authors, they only showed up consistently at amounts below 30 grams per day. Bigger portions add no extra benefit; they just add calories.

Chocolate in a training lifestyle

With an energy density above 5 calories per gram, chocolate is hard to fit into a tight calorie deficit. If you eat chocolate regularly, weighing it deliberately pays off — according to a study by Wansink and Chandon (2006), intuitive estimates undershoot the actual amount by 20 to 30 percent on average.
