I started protein shakes and liked them... there are lots of low carb options out there that taste good! Like SlimFast's low carb version, or even Muscle Milk Vanilla flavor ( I like it with water instead of milk cause then it becomes too sweet and rich ). And you can add a spoon of peanut butter to it or half a banana a week out of surgery. Post op, I did a lot of Muscle Milk strawberry flavor, premixed individual cartons - those were great! Give some of those a try!
