Any low calorie snack (boredom food). Calories in coffee?

okay so I tend to like little snacks and nibble on things when im at home... bored... not cause I'm hungry (we all do it sometimes) do any of you have any like 20 calorie-30 calorie recepies. Something like a smoothie (like lots of ice) with some fruit and coffee or something? I don't know haha something like that... as well... does coffee have calories (like without sugar/cream etc)?

coffee has 5 calories or so per cup. I will add it on to the sugar/cream but if I'm having black coffee then I don't bother counting it.

Great boredom food... SUGAR SNAP PEAS. :)

Keep a container of cut-up fresh veges, like celery, carrots, radishes, summer squash, broccoli, cauliflower, bell peppers, etc. in your fridge. You can snack on those all day for very few calories! Sounds old fashioned but it works for me!

Cheerios, yogurt, sugar free pudding, jello, gum.

snack on fruit like i am right now (a grapefruit)

Have you tried Laughing Cow Lite cheese wedges?  It's very nice with celery.

1 c. almond milk with loads of ice and 1 TB of cocoa...for a simple chocolate shake...mmmm...that would 55 cals...course, you can add vanilla instead or extract of peppermint or orange and then it would be 40 cal.
