Sick and struggling!

First of all, congratulations on your loss!

When sick, it's better to eat at maintenance for a few days (until you're better) and take care of yourself. You need to be kind to your body while it's struggling against an illness or you risk prolonging said illness. You need to give your body the nutrient and energy it needs to fight off what ever bug you picked up.

Be kind to yourself. 1 week over the span of an entire life is negligible.

Good luck.

Select "sedentary" as your activity (you're not going to be moving much if you're sick).
Select "maintain my current weight" under what is your goal.

This will give you a calorie estimate based on your stats on how much you need to eat to maintain your weight.

I usually try to stay just a smidgen under that number just because of logging errors.

Your weight might go up a bit. This is due to a combination of more food in your intestines and added water weight (often more food = more carbs and those cause added water weight).

Once you're feeling better, just go back to the page I've linked above, and select the suitable weight loss goal and simple return to business as usual.

Good luck and get well soon

you do nothing, you get better

Rest, get plenty of fluids.
Don't worry about diet and exercise so much until you feel better.

Sleep as much as you can. If you're craving something, eat it. Drink some orange juice. Get better and start another day.
