I think the percentages listed in that article are just the average.
My doctor did not give me a weight goal - but felt that most of my weight would be off after a year or so. My body would 'settle' by then to what it wants to weigh.
I used to always beat myself up over my weight until years ago I saw a doctor that had this special program. It was a weight measurement they use in the space program. They put a little wire on my right big toe and shot these whatevers into my system. You don't feel anything.
Anyway, when it came back there was a lonnnnnng printout on the details my body composition, water, fat about 7 pages... lots of stuff. I didn't even care about all that stuff because I knew I was in good health. BUT the one thing was ....
it tells you what YOU should weigh. (Not someone your height etc) but exactly what
YOUR body should weight.
IT SAID I SHOULD WEIGH 168!!
I almost dropped a lung when he said that!!!!!!!!!!!!
why, because allllll those early years I would starve myself, workout etc... but no matter how much I tried, I could not get past
EXACTLY 168!!. Can you believe that? A few times I was able to hold 165. Once I even hit 150 .. but that literally only lasted about 5 minutes. Hee hee! I had to eat!!!
So even though I would like to be smaller - my realistic weight goal is now 165. This is because I gave my sister a kidney a few years ago and that's about 3 pounds. Umm of course, I'm older now ... but still I'm shooting for 165 or ... thereabouts!
My doctor also gave me this general guideline:
1. 6 weeks - should lose 10 - 12% of my weight
2. 3 months 15 - 18% of my weight
3. 6 months 23 - 27% of my weight
4. 1 year 33 - 38% of my weight ... (which is 175)
The goal I've (re)set for myself of 165 ... is a tight 10 or a loose 12. But even if I only get to this 38% of my weight I will weight 175 which is a solid size 12and I will be WELL into the 'human' range.

175 on my frame is very, very nice!!!
I haven't weighed in for weeks ... no sense upsetting myself

but I know I'm a slow loser as I was not quite what the guide said I should have been at week 6. I'm coming up on my 3rd month out .... hopfully I make that goal range.

We'll see.
I'm not so worried though ... as long as
I'm losing weight ... I'm happy. I can tell that certainly by looking in the mirror ... even without the scale.
I just can't bear to be GAINING anymore weight which I surely would have done by now without wls!
