Don't despair Loqui. You did not gain 5 pounds of fat in a few days. This is water retention and something we all have to deal with to some degree or another. Are you anywhere near your TOM? If so, that could be an easy explanation. Your hormones are in a bit of a quandry at the moment due to suddenly changing the way you metabolize fuel. It's going to take some time for everything to even out.

I lost 13 lbs on induction and then gained 6 of it back within a few days as well. BUT, I am feeling so much better and I am getting smaller. I can tell by my clothes. Around TOM time, things get a little bit tighter then loosen up again as soon as it's over. Also, all that protein you're eating is being used to rebuild muscle and other tissues at the same time that you're burning fat. Net result on the scale can equal stalemate or a gain.

This is the major reason why I am so much against using the scale too much, especially at first. It's going to fluctuate and make you sad and frustrated. So just do what I did. Put it away. Don't even weigh yourself except for once a month. Use your clothing as a guide instead. (or measurements) When we get so obsessed with what a silly piece of metal tells us, it tends to get discouraging and makes us wonder if this WOL is really for us.

Instead of worrying about the scale, focus instead on how good you're feeling now....how much energy you have....how wonderful it is to be in CONTROL of your eating for a change and not be hungry. If you choose to take this kind of positive attitude instead, time will just fly by and your clothes will start falling off of you before you know it. If you make it a day-by-day struggle with what the scales say, then it's going to be painfully slow and discouraging.

Keep the faith, girl. I know you can do it!
