Mine presented as a very high fever along with loss of appetite and unwillingness to drink.
The first and last of those combined to create severe problems related to dehydration, such as when I briefly passed out in the kitchen and had an uncontrolled fall into the furniture there.
So my advice tends to be focused on that problem: force yourself to drink as much as you can (I was given a target of two liters a day which proved to be less than would have been ideal, but it was about all I could do to drink that much in a day), stock water or, better, sports drinks close to your bed so that you don't have to get up before rehydrating, and ideally have some people around you who can check on you and bring you things.
When I did not appear to be getting any better after three days, and a splitting headache persisted through a fairly aggressive schedule of tylenol and ibuprofen, I visited an emergency room and was given antibiotics. That's when I learned I had pneumonia.
Medical advice on loss of appetite was: don't worry about it; whether you eat or not doesn't matter at all (assuming you and your appetite recover on a reasonable time frame).
Back on topic, this is true in general of formerly healthy people. Lack of food will not cause any problems in the present, because you were not suffering from it in the recent past. And unless it persists a long way into the future, it also won't cause any problems in the future, because you will regain access to food and start eating again.
