You look like you are doing great on induction 4 pounds in 5 days is pretty good.

Don't worry about putting that pound on. It is your body adjusting and just holding on to a little water while it sorts itself out. It is very tempting to weigh yourself everyday, I know I do, but I only record my weight once a week. Alternatively you can weigh every day and then average it across the week. In that way you get the bigger picture.

I have read many peoples experiences on this forum who have lost a lot in the first week to put back on a couple of pounds in the second. It is only temporary. After all, how long did it take for you to gain it in the first place. Hopefully it will not take as long to loose it.

Just keep on doing what you are doing and the pounds will come off when they are good and ready. You do not seem to be doing anything wrong, so just continue.

Every success and let us know how things progress.
