I know this information must be useful to someone out there who is considering weight loss surgery and is on a budget, or who has had weight loss surgery and on a budget. Everything seems to cost more lately, so I compile the most popular protein shakes in this list. I tried to include those I know are the tastiest, but I have not included which I prefer. Please feel free to comment as to which you like the best. I will say, the one that's the most expensive is the one I like the least!
