low carb low calorie snacks

The internet and book stores are filled with it. What you like is subjective, you are supposed to hit your calorie target, healthy adults don't need to snack, snack foods are typically calorie dense and nutritionally poor (but taste great, that's why we like them and that's why they're easy to overeat), low carbs tends to take away the need to eat between meals. At least go to the Recipes section and ask there.
