why does this happen? its frustrating!!

i ate horribly this weekend and the scale says im up four pounds. but i know that i didn't eat enough for 4 pounds. i ate less than 3500 extra calories. will this weight go down? if so how soon?

I'm sure you've heard it before...but you would have had to eat 3500 calories over maintenance to gain ONE pound. You're most likely bloated from water retention because of a higher salt intake. Give yourself a week and you'll be back down.  In the mean time, lots of water to flush out the bloat, do some good cardio/weight sessions to sweat it out and don't stress.  ;)  You gotta live a little.  Just get back on track today.

i hate that its probably going to take a whole week to get back down. argggg!!

It may not take you that long.  I know for me it takes me anywhere from 4 to 7 days to get back down after a really bad weekend.  It's only a number on the scale.  Don't worry!!  

I am right there with you - I am so upset this morning, and trying to be patient to weigh again tomorrow.  I was at 130.2 for the last 5 days, didn't drink even ONE beer all weekend, get on the scale this morning and it read 133.4!

AGH!!!  I stayed on track all weekend except for going over by 200 CALORIES on Saturday and Sunday.

Totally frustrated with you, hopefully tomorrow will be better news!

If I have a bad weekend I just suck it up, move on, and don't weigh myself for at least a few days.  No point in hopping on the scale right away, you're only going to upset yourself with all of the water you're retaining.  Don't worry, it'll go away.  ;)

i can't wait till i get home from school to see what i weigh. hopefully it's gone down!
