Protein Isolate? Protein Concentrate? Super Duper Blend? All I know is the one I got at WalMart smells like rotten meat and I cant drink it! 

Many of us never put a protein shake to our lips before our weight loss surgery and suddenly they are our life. Not all protein is the same. There is a reason many are cheap – there is a reason many taste bad – there is a reason your hair is falling out – there is a reason the smell of the powder you bought at the warehouse store makes you gag. Protein does not have to be a punishment if you know the difference.
