I'm not sure if I'm convinced of the idea either.. but I'll be interested to see how my weight loss fits into the theory from here on out.
One of my 'set points' in weight was 257 pounds, which I was for many years. I hit that weight about 2 1/2 months ago in this weight loss journey, and have been STUCK like glue to it ever since. I did eat maintenance level cals for a month of that time however.. so I can only say I've been plateaued at that level for about 1 1/2 months now.. but it's interesting that I'm stuck here and this was my weight for many years. Hmmmm...
My other weight that I held for many years was around 240 pounds. I'm super interested to see if I hit a plateau at that weight too... I'll check in with this post when I get there!
