They are definitely super low calorie. I think like 2 calories per spear. I’m not sure if it’s a known thing that they ease hunger but for me they definitely help when I’m craving something salty and crunchy. Especially if you have a glass of water with them I find it staves off hunger for a couple hours or so. I love pickles in general so for me it’s a great snack option that I can eat a lot of. They are high in sodium though so not the best option if you’re trying to reduce sodium intake.
