Body set point

How long does it take to lower the body's weight setpoint?
Over the last few years I found that at 71 kilos, my appetite seriously decreased till I returned to 70-69 kilos. This was a 26.5 BMI. I have worked very hard and am now fluctuating around 65.5 kilos. My tolerance for the work and hunger has finished. I will go to a maintenance mode till I recover my tolerance and can make more efforts toward 63 kilos. How long should I anticipate till the unconscious balance of the weight set point kicks in to help me?

I don't know that set point is the phenomenon you think it is...
A lot of what you experience has correlation(s) to how large your deficit was while you were losing, how long you maintained that deficit, what 65 kilos means to your BMI and other factors.
Here, read the first couple pages of the Refeed thread, I think it will answer all your questions:

Some say there's no such thing as your set point but here's some recent MFP takes on it.

big hug momma bird.....
OP, I don't believe in a set point. More of a settling range. From what I have read, there are many factors that go into this. First, weight history. Leptin is a master hormone produced by fat cells in relation to their size. It is sensed by the hypothalamus and that controls hunger and metabolic rate. So, when you lose body fat, leptin lowers and there is an increase in hunger and a decrease in metabolic rate driving you back to the lvl of leptin your hypothalamus likes. It has been suggested that as one increases in weight for longer periods of time, this level raises, making it harder to maintain lost weight. Second, there is environment. This is a rather long one. Our environment plays a role in where out body sits. There is evidence that a diet higher in Less refined, lower energy density, less palatable, higher in fiber, higher protein foods, it helps that set point lower. If we look at several kevin hall studies, many more rodent studies, when a diet is switched to a more "natural" dietary pattern, many people spontaneously reduce calories and do not complain of hunger of hunger. Third is genetics, some people I think are just wired to have a bigger appetite and response to food reward. This is usually centered in the brain, not the fat cells. Fourth is physical activity. What the research suggest is, people who are more active are better at matching energy expenditure with intake. We also see people who are more active post weight loss keep the weight off better. I think this goes farther than calories burned. There is new information that there is a gravity system in our bone that remember how much we weigh to help us not gain or lose weight.
So, to sum up.... Eat a less refined, Low E.D. diet, higher fiber, higher protein, less rewarding diet. Full of fruits and veggies. Exercise, sleep...... See what happens. A 26.5 bmi? thats just slightly over weight. How about trying not to gain weight? Just a thought.13 -

Well this is a fascinating sentence...@psychod787

Ma'am, there isn't much for me to teach you. YOU are the unicorn! I will gladly learn from you. The gravistat does not seem to be as vigorously defended as the lipostat. It seems to act independent of the leptin system. The weight of a person is sense by the osteocytes in the bones and decreases appetite when weight is increases. This would only make sense because as a prey animal, we would have to climb and run. I think the modern food environment of hyper palatable / energy dense foods overrides it. We just eat past it because satiety does not always track well with caloric intake. I think that people who are more active might increase the load on the bones. Thus making caloric intake more in line with needs.4 -
Well, the increased load on the bones would then be more pronounced with lifting
I am teetering on not knowing WTH I'm talking about, so I'll just be quiet now.4 -

LOL ma'am I so very rarely know what I am talking about!
Yes, I think weight lifting does have an effect, but far smaller than just standing and walking. In a training session I may put 20 tons of load on me. Sounds like a lot, but compared to walking, not really. You have to figure every step I take is over 200lbs of pressure per step. I think weight lifting doe other things to the body. We have seen where it helps mitigate the increase in skeletal muscle efficiency post weight loss. Probably dt protein turn over and the increase in cellular mitochondria energy use.
I, unlike others, think the equation is a far deeper subject than eat less more more. While yes, you need a caloric deficit to lose weight, dt over lapping systems in the body making it harder, it is far more complex. We have to learn to work with our brains and bodies, not against it. I was reading an interesting research review today. It was on the impact of green veggie membrane supplementation on obese women. It showed that it had a similar effect as liraglutide on glp 1 production. The women in the supplementation group ate less without being asked and lost more weight than the control group. So while a calorie is a calorie, the kind of food that calorie comes from can have remarkably different effects on hunger and satiety.5 -
liraglutide on glp 1 production
k. whatever you say.
I am not a medical professional. I am more like Rachel.3 -
I do agree that it is far more complicated than eat less move more, HOWEVER, eat less move more gets the job done.9

Very few sensible people here have ever said otherwise, I think.
I feel like you, Psycho, were driven a bit into the minutia because of taking an extreme-ish approach in the first place, that got you some extreme-ish effects as a result. Maybe I'm wrong: I often am.
I'm with cmriverside:cmriverside wrote: »I do agree that it is far more complicated than eat less move more, HOWEVER, eat less move more gets the job done.
. . . for most average cases. Satiety, in that context, seems to be somewhat personal & individual, anecdotally, though I have no doubt that the aggregate data reflect commonalities/generalities (i.e., studies find some statistically significant stuff), and the minutia and mechanisms are interesting, even though most of us can operate successfully with a few, much simpler, rules of thumb.
OP, Sarah - the "Refeeds and Diet Breaks" thread posted above is probably the best specific answer you'll get.
I don't personally believe in set points per se (I think bodyweight is significantly an output from habits that we find sustainable and happy-making). However, I do assume - as per the linked thread - that we stir up some interesting body systems when we intentional cut calories, and that that has consequences for hunger, appetite, cravings, fatigue, mood, motivation, and more. Those are things that influence us, but don't *necessarily* control our behavior (just make certain behaviors hard (require "will power" or "motivation") or easy).
To the extent that you're experiencing some diet fatigue, or hormonal snap-back, or whatever, I think the linked thread will have suggestions about what time it might take on average to settle it, but sometimes individuals vary. You'll possibly need to run your own n=1 trial.
Best wishes!

Thank you all for the comments and the threads. I read them all , havent seen the ytube film yet. The term "refeeding" has such difficult associations... I think my conclusion is that I need at least half a year of maintening before I relax my grip on calorie watching.3

Another n=1.
My setpoint was "about a pound or two heavier than last year" for about 30 years. This doesn't really sound like a setpoint.
Then I had enough of that.
There was definitely hunger at first, and I was able to manage that. It got better, and my hunger adjusted to I got to a point where I actually enjoyed the "empty" feeling part of the day. It made me appreciate food even more (hard to imagine because I love food), and it encouraged me to eat more mindfully. Even before I started to lose, I could easily skip eating for most of the day and then make up for it later. My ex never understood how I could go through the day and do physical activity and never have breakfast and even a late lunch. Worked for me.
I wish I had a "setpoint" that I could somehow reset and then no longer have to track my intake and activity. Maybe I'll find it in a decade. For now it's just about paying attention and trying to make sure to eat things that fill me up, fuel my body, and stay within my goals.

@psychod787 I was outside irrigating fields until 10:30 pm but that one statement ..I kept mulling it over. The gravity system in our bones that remembers how much we weigh...dem bones dem bones dem bones. Everything has a memory. What about space bones, living on the space station. What do you think?
Long term exposure to zero gravity causes loss of bone and muscle mass. I recently had a dream that I traveled to Mars but I think I'm better off here with gravity for dem bones. Thanks for your thought provoking posts.
Sidenote: I could easily eat my weight in gummy bears, live on gummy bears but that green vege membrane supplementation made an impact on me, too. I ate whopping boatloads of that at lunchtime. I know about the transition from a sugar burner to a fat burner.1 -
So interesting.... I definitely have a set point. I was looking into how to eat and found some help using the zigzag method... Go to calculator.net. You plug in your weight activity level, etc. And it give you a weekly zigzag calories goal tip confuse the body's set point. Maybe I will try it......0

I see to have 3 set points around 15 pounds apart. I'll just sit there pretty stubbornly and then run from one to the other.1

Try to think of it as a diet break then. We need to give ourselves a break now and then from the constant restriction.0 -
I have to say personally I'm not a believer in the body having a set point.5

Set point theory was popularized in mainstream press around 1980 or a little earlier than that. 40 years is a long time for a hypothesis to garner evidence. Is there any scientific evidence supporting the set point mechanism at all?
The likely explanation for the observation (bodies tend to stay the same weight) is habits (that don't tend to change) rather than any biological mechanism.6
