Okay, there are some energy and sports bars that are good for you. But, energy bars are also the ultimate test of reading labels. While, at times, these are a better choice than the bag of chips or twizzlers sitting on your desk, but they may contain high levels of carbs and sugar. Energy bars also depend on you, as an individual. Though a particular brand works for your friend, doesn't mean it'll work the same way for you. 

How should you find what works best: Find a dietitian who can help what works best for you

Everyone is different, which is something that we have stressed probably a million times. So, it's vital to ask your physician any questions that you can about what may or may not work for you. If your physician cannot answer these questions, find someone who is trained to know what you should eat as a diabetic like a dietitian.

And, while taking their advice, find snacks that can satisfy your fix and that can be considered low in carbs, like light popcorn, string cheese, or almonds.
