I substitute the LAWL snacks (most of which I think are disgusting) with 90-100 calorie packs of cookies and the like all the time. The extra sodium really doesn't bother me, because I usually drink upwards of 3 L (96 oz) of water a day (sometimes as high as 4 L!!!). As for the other differences in nutritional value, I figure it's still better than choosing a really heavy starch (like a bagel). Generally it hasn't slowed me down, as long as I don't get stupid and think I can get away with having more than one bag
