What is your fitness goal? Gain muscle, lose fat, etc?
Do you not like eating "whole foods"
Agreed, stick to eating food, stay away from the protein bars unless absolutely necessary. A lot of junk in them that you'd have to read the fine print to see, many pack a lot of cals too. Most that are carried at my neighborhood GNC range from 350-450 cals, and provide max 30g protein. for 400 cals, you could have an 6oz chicken breast, some veggies and sweet potato or a bit of brown rice - hitting all your macros, and breaking down quickly. Protein bars are processed, so the junk sits on your stomach, harder to break down.
