Same here. I very much value my sense of smell, and the one and only time I got Covid so far, a year and a half ago, I had very mild symptoms otherwise, but utterly and completely lost my sense of smell. A mentholyptus cough drop may as well have been a sugar pill for all I could smell or taste it. But! My sense of smell came back completely in a couple weeks to a month. So don’t despair.
Mrs. solost, on the other hand, claims her sense of smell hasn’t been quite the same since she had it (same time as me). But I’m skeptical of this, since whenever I try to have a drink or two on a weekday she can smell it on me instantly 
Oh, and your hope to lose some weight while you can’t smell? Nice optimism, and I hoped for the same thing. But don’t go shopping for skinny pants just yet
