Okay so the past two days COMBINED...I've probably eaten maybe 500 calories?
Yes I've had the lovely stomach flu.
As a result I'm down 7.4 lbs this week (that's a total of almost 17 lbs in 3 weeks). Now we know I'm likely going to gain some of this back once I get back to eating normally. But is there any chance of me NOT gaining it back? I mean, there should be some positive out of puking for two days straight, right?

Just curious.

You'll probably gain some of it back, but there's a possibility you won't gain it all back. I'd just keep trying to eat what you can (and lots of fluids).

Please please please stay hydrated! If some of your weight loss is due to dehydration (and it probably is), it can be dangerous.

I'd guess that you have lost less than a pound of "real" weight. People just don't burn up a lot of calories in 2 days. The rest of the scale loss is water weight and the weight of undigested food that is normally hangs around. Please don't be upset if nearly all of it returns as you recover. It means you are back on the healthy weight loss path!

Feel better soon!
