Covid weight loss

I had covid and was in bed for 3-5 weeks with a fever. I did not eat much because everything smelled and tasted so bad, I drank water, milk and ate some Finnish salted Licorice. I lost 9-10kg because my body started eating my excess fat. After covid, I began eating 3-4 eggs in the morning and at lunch one orange, later at dinner a kids meal of whatever we made that day, oh and at work, I'm drinking apple cider vinegar with lemon, honey, ginger root, and water, been losing weight like crazy. And NO snacking. Hope I'm not drinking too much.
