Lowest calorie snacks
These are the snacks with the fewest calories in a normal portion, from a single Ferrero Rocher up to a handful of walnuts.



Numbers for the portion shown, the same as on each food's page. Sports are for someone of about 70 kg.
A Ferrero Rocher tops the list because it is one small chocolate, not because it is light. Portion is doing a lot of the work here.
Beef jerky and popcorn are the ones that actually fill you up for what they cost. Crisps, Pringles and Doritos are fine in a small bag, it is the sharing bag that adds up.
Nuts are further down, but they come with protein and keep you going. A handful is a snack, the whole bag is a meal.

They are dense, but a small handful is fine and gives you protein and fat that keep you full.
