I don't know when I'll be allowed solid food again. And I love food. Today I cannot eat anything more solid than Jello. I can drink "clear" liquids, which do include Coca Cola. Basically I can eat or drink anything that you can pour out of a glass and it leaves nothing behind, coating the glass.
Tomorrow I get no food or drink whatsoever. And I know from experience that I'll not be allowed anything more solid that Jello or a popsicle during my week in the hospital. Maybe towards the end I'll be allowed cream of wheat or some brothy or creamy soup.
Anyway, it's true that you should be careful about what you wish for. If you wish to lose a few pounds it may happen.
