It helps some when one can't taste things to have more texture and temperature variation in food, so at least you have those sensations. With me, the grieving process takes about 1.5 years with a major loss. My TBI was 31 years ago, and my olfactory bulbs were impacted by the injury. It took a few months to be able to taste anything, and then it was butter, chicken, and chocolate. Didn't do much for controlling my weight, but did bring to mind the "everything tastes like chicken" joke. After a year and a half I started to taste more things, but the complexity and strength of flavor was muted. After 8 years I could taste most things, enough that I didn't know what I was missing. Beef was the last. I still can't tolerate the smells of cigarettes or perfume, and am probably not detecting some odors. Smell and taste are a major (hopefully temporary) loss, hopefully you can fill that space by finding fun interests, hobbies, or other escapes.
