I read somewhere that it is very common to hit a wall at around 15-20% weightloss. At that point, your physiology is just designed to put the brakes on it. The stall can last several months until your new, lower weight becomes the new normal. Then (so I read) your system will allow weight loss to resume, though probably not as quickly as before, and you will probably hit another stall after losing another 15-20% (though, in your case, that’s probably more than you even need to lose).
Not everyone experiences this, but it seems to be a common pattern, and it matched my experience. People at this wall are often advised to buckle down and give up various things, and sometimes that seems to work, but sometimes it’s probably just a coincidence. I gave up dairy and sweeteners when I hit the wall, and I lost a few pounds, but then I gained them back, and my weight just kind of bounced there. Adding dairy and sweeteners back in didn’t seem to make things any worse, but it did make me a lot happier.
One thing I found helpful was to log my weight daily in a spreadsheet and produce averages for the month. In July, for example, I gained two pounds, but my daily average for the month was actually down three pounds from my daily June average. That was enormously reassuring. If I had only weighed at the beginning and end of the month, I would have totally missed that trend and thought my entire month of hard work was for nothing. Three pounds down isn’t huge, but it’s progress, and, most importantly, it’s in the right direction.
But, of course, if you discover the magic bullet that gets you rolling again, we’ll all want to hear about it.
