To be honest, I am the complete opposite... if I eat popcorn before bed, I am always down the next morning (not that I eat it that often). Funny how different foods affect different people in different ways.
Hmmmm.... I was wondering the same thing when I stepped on the scale this morning. I dont eat popcorn often, but I had a lot of it last night - air popped with a bit of garlic salt. I was up 1 pound and my tummy felt a little bloated. I am interested to see what others' experiences are.
May be going out on a limb on this but popcorn is VERY absorbent and if you're also drinking a lot of anything before bedtime maybe by the time you've woken up in the morning it's still retaining some of the liquid through the digestion process ...either way, does the weight not come off in the next day or two??
