Eating when you're sick

Like many people at this time of year, I've come down with a cold/sinus infection. I've had a couple of days where I didn't work out (other than my campus trudging -- I couldn't cancel classes due to illness because of all the snow day cancellations), and I have been drinking orange juice, which has a lot of calories, and just wanting to eat soup. I'm also eating more fruit. Today, for instance, I had blueberries, fresh pineapple at the meeting breakfast spread, an orange, and orange juice. If I do end up drinking a lot of juice and eatingmore fruit, should I be reducing my intake of other foods so that I'm still at a deficit? I'm not usually a juice drinker because of the high calorie count, but now I just seem to crave it. Plus, it's easier to wash down all the decongestants, etc. with something sweet. If I'm eating less of other foods due to juice consumption, do I need to worry about protein macros,etc.? The only protein I want presently is what's in a bowl of soup, although I did manage a small slice of veggie pizza at a faculty meeting because that's what was served. When I recover, should I be adding extra time to my workouts to make up for time lost and to restore muscle tone? I was up to light strength training today, but hadn't done any since a modest leg workout Monday, and it seems as if already I'm seeing my body get slacker.
