I've been eating clean for a week now (that is a LONG time for me). In order to this, I have had to use protein bars. Sometimes, I'll be at the mall or over at someone's house during a 'meal' or 'snack' time. It is very hard to eat protein on the run (a can of tuna, etc. is a tad cumbersome to open and eat while walking through Target). So I keep Myoplex Lite bars in my purse for days when I'll be out and about. They have 200 calories and 15 gm of protein. Anything with less than 15 gm. of protein I try to stay away from. Granted, this isn't eating food in it's most natural state, but it was a lot better than grabbing an ice cream cone or a bag of chips, like I used to do. Have fun!
