Found an informative slideshow about foods which contain 40 calories or less. I tried to post the link but apperantly I don't have 25 posts in order to do that -_-.

Here are the counts:

Arugula Calories: 4 per cup
Asparagus: Calories: 27 per cup
Broccoli: Calories: 31 per cup
Broth: Calories: 10 per cup (I think this might be questionable since no broth is that same.)

Lettuce: Calories: 5 per cup
Beets: Calories: 37 per 1/2 cup

Thanks for this list.

I see a trend! This is why we are told to eat our fruits and veggies .

I just realized that I never count calories in my garlic......;-)

Thanks for the list. That will come in handy. P.S. 3 more posts to go.

I wish there was a 40-calorie donut. Quick someone make a recipe for veggie donuts!

oh crap! I don't count calories in my garlic either! And I eat it like my husband is Dracula (which..could be hot?)
