Low-calorie foods up to 40 kcal per 100 g

92 foods on 17 Fit meet the EU criterion “low energy”. The lightest: konjac, clear broth and espresso.

In the EU a food may be called “low energy” when it has no more than 40 kcal per 100 g, or 20 kcal per 100 ml for a drink. Most of the foods that qualify are vegetables, mushrooms, some fruit, broths and light drinks: mostly water and fibre. The table groups them by category and shows the calories in a usual portion and how much of each food makes 100 kcal, which helps when you want a bigger plate for the same calories.

How the list is made

Every food on 17 Fit that meets the EU’s “low energy” criterion per 100 g: at most 40 kcal, or 20 kcal per 100 ml for drinks (Regulation (EC) 1924/2006). Foods with under 5 kcal per 100 g, such as tea and black coffee, are left out, and so are the foods whose usual portion is under 10 g. Values from the 17 Fit catalog, for the form each page leads with.
