Lean Body Protein Bars

I'm on a low carbohydrate, high protein diet. I eat mostly egg whites with guacamole chicken breast and some vegetables. I also drink protein shakes Muscle Milk.
Anyway, I just discovered these Lean Body Bars. I really like the taste, but I think they might be a little high in sugar.

Am I ruining my diet by eating these?

Here are the nutritional facts.
Calories - 330
Total fat - 16g
Sodium - 190mg
Potassium - 150mg
Total Carbohydrates - 26g
Fiber - 2g
Sugar - 15g
Protein - 21g

Thank you!

It looks like a portion already exceeds the consumption of carbohydrates generally attributed to maintaining a diet low in carbohydrates ... unless you exercise regularly and I am allowed a high intake of carbohydrates ...

Even subtracting the fiber from the total carbohydrate, it is still high enough to stay in "fat burning".
