Hi - I am 6 days post op. I am in phase 2 of eating where i am ok to eat soups, jello, yogurt, etc.. but I'm supposed to be getting 64g of protein per day. My problem is that i can't tolerate any sugar substitutes. I am really struggling with things i can eat (drink) that are high in protein but don't have any fake sugar substitutes. I have tried the GenePro tasteless protein powder as well and couldn't keep that down either. Does anyone have any other suggestions of foods/drinks to try that do not have sugar substitutes but are high in protein? There is only so much plain yogurt, tea, broth etc... i can take in and am no where near the protein goal with those options. Any suggestions would be appreciated!
