power bars for breakfast

if you eat a power bar for breakfast will you gain weight?  do you guys have some ideas on a quick but very healthy breakfast to eat when your on the go?

Admittedly, I am very bad about eating breakfast. I always have been. I like a hard boiled egg for breakfast (or really anytime). Another thing I'll do is cook some plain quinoa in my rice cooker one evening and keep it in the fridge. For breakfast I'll do a cup of it with some honey and cinamon and throw it in the microwave for a second.

I'm not sure about the Power Bars since I don't think I've ever had one. For a while I was doing the FiberOne Apple Struesel bars.

I don't think so if you're staying within your daily calories because most are very high in protein.  I do oatmeal with lots of cinnamon and a few almonds  and oj which only takes a couple minutes.  I also do brown rice or eggs. 

I never lost weight eating power bars because I got hungry fast . I find that a protein shake I like nuti burn by natures sunshine realy last for me and I add blueberries or 1/2 a peach good luck!
