Stovetop popcorn is yummy. I agree that its just the popcorn calories unless there was oil in with the popcorn.
I make microwave popcorn most of the time myself. Their calories always confuse me too. The unpopped calories are just so much higher than the popped version it makes me wary lol But i guess not every kernel pops and most of that oil and butter is on the bag. *shrug*
