21. Dark Chocolate
A lot of us are big chocoholics and that's fine as long as you go for the really dark ones.
The dark chocolate you buy should be made up of 70% cocoa, has little sugar and packed with antioxidants.
This is a wonderful substitute for plain chocolate. Another perk of eating dark chocolate is it helps to lower your blood pressure.
But don't over do it, just eat a few cubes and you will be filled for the night.
One of the few reasons why popcorn is on this list is because they are very low in calories and are 95% fat free.
Just make sure to avoid using butter and use lemon powder to flavor instead.
