Protein bars, they’re a tricky one to know about and many wonder whether or not to eat them when dieting.  To some degree they’re good.  They can fill you up fairly quickly, and realistically speaking, many have used them successfully.  They make a quick and convenient snack that is generally recognized as being better than chips.  But you should be eating a few small meals per day if you are going to use this rather than 3 big ones or even 2 big ones. 

Realistically speaking they differ.  You have to choose the right one to be sure.  Some are high in sugar, some almost eliminate sugar.  But they are all high in calories, which is part of what makes them so quickly filling.  The long of the short is that not all energy bars are created equal, not all protein bars are created equal.  So you have to actually look at the nutritional facts and choose accordingly.  You also have to look at your existing program and see how many calories you can actually handle from them and how many you are actually burning off in general terms.  So it depends on you and the energy bar combined in so many ways.
