Just curious, for those that like protein bars...
Why do you use protein bars? Is this a "fill-in" of convenience for crazy, busy days when there is literally is no time to eat regular food, or do you feel it is important/desirable to eat them as part of your normal plan? If so, is it a known indulgence, i.e. sugary-but-better-than-a-regular-candy-bar, or is it perceived as healthy? Do you have any concerns about excess protein intake affecting your kidneys or depleting your body's calcium?
