Buy low calorie Tv Dinners, around 180-280 calories each. Popcorn has low calories and is filling. Eat lots of fruits/veggies, as they are negative calories and won't count against you.

SO SORRY!

I meant to type 210, not 110. I am definitly not underweight, XD

Sorry, but I'd laugh at any adult wearing them.

A lot of kids have them at school, and personally I think they are immature, but do whatever you'd like. You wouldn't be completely standing out, but yes, will look immature.

Apparently they were a big hit in the closing ceremony of the Olympics:

More adults are wearing them.

I say do whatever you want in fashion if it fits your personality.

Prince the musician wore them all the time and he was considered to have great fashion sense and was invited all over the world, including France and Italy,  to famous designer fashion shows.
