So tonight I work I forgot to bring my stuff to make a protein shake so I just purched a protein bar. I only ate two bites of it though. Is this OK???

Protein bars are one of the available supplements to get in your protein. But generally, this is not right after surgery. Several months after surgery, I began to use Protein Bars when I was up and about (and couldn't drag along my blender). They are costly and I generally buy them over the internet. But bars are offered in so many flavors it is best to buy a sampling and pick one you like. I use Quest Bars (Coconut Cashew). There are many types of protein bars. Some contain too much sugar and should be avoided.

Quest Bars have 20 grams of protein and 1 to 4 net carbs depending on flavor. I eat the for breakfast a lot but can only eat 1/2 at a time.
