I was a not hungry or interested in eating person too. I’m glad it lasted for quite some time. But I knew I had to eat & did find eating to a routine helped me meet my goals. Don’t worry too much if you can’t meet your caloric goals yet. Focus on getting all your protein in first, then vegetables & then carbs & starch last if you can. Make sure you let your dietician know you’re struggling with the quantity of food at the moment. You can only eat what you can physically eat.
The change to your taste buds & maybe sense of smell is temporary so things that taste disgusting now will be okay again in a few weeks. Also your tummy can be a bit sensitive & their may be foods that just don’t sit comfortably or heavily. Usually this passes too but there may be things that you will always have to avoid. I still can’t eat bread, rice, pasta (even vegetable low carb ones) & potatoes. Try some plant based proteins until you want to try meat again.
