Wow...
Liz your original post was made about a year ago, when I was about 40 lbs. down and losing 1-2 pounds a week, thinking it would go on forever. It did, until about May 2004, when I stopped losing. Since then, I've lost about
thirteen total pounds -- I used to do that in a month.
I knew it would happen, but my understanding of thermodynamics led me to think that if I kept at it, I'd eventually lose the same amount of weight over time, if I kept a caloric deficit in place. That hasn't happened. After some soul searching, I realized that there has to be something more happening.
I do subscribe to the inevitable truth that, if over time, I establish a 500+ caloric deficit a day, I'll lose. And I have been. But the body isn't a diesel engine and it can't really be treated as such; algebra might not quite apply to its operation.
My skid hit at about 70 pounds lost, in the middle of the range you described. I found something else odd...
Over the holidays, I ate way more calories and way more carbs than usual. Fudge, even nachos and sugary treats at Christmas parties. My weight shot up from 260 to 265...for about a week.
I got back on the diet, and the 5 pounds vanished as easily as the first 70 did! when I hit 260 again, without variance to my diet, I stayed there. It was as if there were a "glass floor" that I can't easily pass beyond. Does this prove the set point theory? I don't know. It sure helps me to believe in it more. Why would that particular five pounds drop so effortlessly -- but not the
next five pounds?!
I also look back to the fall, when I dropped from 272 to 260, all in about 8 weeks. I changed nothing, yet I had a 1.5 lb. drop per week on average. It was as if the body finally understood it could let go of that fat/water, on the same calories and output as before.
I have stuck to the same eating patterns since then, with the variances of the holidays and a Chicago trip that did lead me to cheat some.
Is set point real? Maybe.
I don't see myself adjusting my 1600-2000 calorie diet down much. I know myself and know I wouldn't be able to sustain it.
So, I'm staying the course and hoping for a very modest weightloss of maybe 15-20 pounds for ALL of 2005. Anyone else?
