Replacing calories lost when sick?

This may be a touchy topic so please bear with me? :flowerforyou: Context: I am overweight and have been successfully dieting and exercising to lose weight gradually over the past four months.

I have been diagnosed with IBS and have a really sensitive digestive system. Every so often I eat something (usually an unexpected combination of somethings) that promptly gives me diarrhea. This is not fun. :explode:

The next day after one of these episodes I typically find myself to be monstrously hungry. So I eat a little more than usual. And I see that I'm not ballooning up afterwards, my weight trend remains pretty steady.

What I want to know is how many calories am I losing when I get sick?

I want to know what is typical, so I know how many calories I should be replacing, without overdoing it. (If I was an inborn expert at judging food quantities I wouldn't be counting in the first place ) Today is an example. I was sick last night, and I have eaten a little more than usual today. :drinker: If I can have a ballpark idea of how many calories I lost, I can say "hmm I haven't actually made up for what I lost yet, so I'm ok", or vice versa.

You can see why this is a sensitive question: googling on this I came up with all kinds of returns on how horrible it is to be bulimic. But that's truly not me, never has been, and I'm asking for the right reasons.

So anybody have a clue?
