I too am having problems getting in my Protein. I was drinking banana cream Protein shakes for Breakfast before surgery. Now, I can NOT stand them. I am one week out from being sleeved and am down 16 pounds. The doctor told me today to add reduced fat Peanut Butter to my shakes. He also said I could blend a very ripe banana in them also. One receipe I can't wait to try is using vanilla protein adding just a little instant decaf coffee to it and I also got sugar free carmel flavoring. I bet it will taste like a caramel frappacino. I am up for any ideas to spice up these protein shakes!! You may also look into getting different flavoring extracts to change the taste. Try adding mint extract to your chocolate shakes. I bet it will take like mint chocolate. Just a thought, my mom and I have been thinking of different ideas today, just haven't tried them all. Sorry I am just rambling on and on. It makes me feel better that I am not the only one that is having trouble getting in all the protein.
Best of luck to you on your WL journey. Keep me posted if you come up with any other protein ideas.
