High protein supplements or bar suggestions?

QuestBar chocolate brownie bar is one of my favorites! Only 6g net carbs and very filling, also helps satisfy a sweet tooth.  

I would use caution on processed foods. They may also have a higher total carb and that may hider losses. Not to mention sugar alcohols can affect some differently. I personally try to stay away from processed foods as much as possible. Home made beef jerky or no carb jerky found online for on the go. Pack of tuna you can stick a fork in is a great one.
