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:

    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

    Well this is a fascinating sentence...@psychod787

    Someday I'll come sit at your feet and you can teach me everything.

    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.

    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.

    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.

    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. B)

    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......

    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.

    ...The term "refeeding" has such difficult associations...

    Try to think of it as a diet break then. We need to give ourselves a break now and then from the constant restriction. :)

    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.

    One wonders whether it would've even gained popular attention, and persisted, if it were not such an appealing reason/excuse about why "weight loss is impossible, and keeping it off even worse!"

    I don't think one can't lose weight and keep it off, but I think people have to understand that the biological changes that happens when one tries to downsize can't be ignored. I like settling range vs set point. Do I think some people can maintain a leaner body easier than others doing the same protocols? Yes. There are genetics that go into it. Does one get obese just because of genetics? No. Though, there are genes that most likely make some people have a higher appetite and hunger signal. There are others that may control how much slowing of "metabolism" one has while losing weight. If there was a "set point", we would never gain weight. We do though. We see overfeeding studies that when allowed to go back to ad librium feedings, most folks drift back down to near their old weights. I think that the maintenance of a higher bf level over time may dampen the bodies ability to get back to an old level. Could it be leptin resistence? The gravistat? Changes in environment? Yes to all.

    No argument with any of that.

    My point was that psychologically appealing theories with X amount of evidence have more impact and duration in the popular imagination than psychologically unpleasant ones with similar evidence (adjusted for some people enjoying perverse things, however). This, even if the thories eventually significantly debunked. Who doesn't love a good excuse, or a plausible rationalization? At least better than we like concrete evidence that our own voluntary choices have some serious downsides?

    Magnifying that, often 3rd parties with something to market will exploit the psychologically appealing ideas in some way, spreading them further. (Can't make much money from an idea people don't want to adopt, though negatively-weighted ideas can be painted as "the thing we're fighting" in a marketing plan, of course.)

    Not saying the above applies in a pure way to set point theory, but it might be in the mix.

    For sure, I believe there are physiological/biological effects and forces to be reckoned with (including genetic ones), in weight gain, weight loss, weight maintenance. Physiology and psychology operate in the same body, and aren't *really* separate, either.

    I'm not sure I see set point as "psychologically appealing". For me, if its true, it would mean I have messed up my life permanently and there's nothing I can permanently do about it. Not very appealing to me!

    I see your point. I do think, though, that it can be a convenient reason that it's not even worth trying to lose weight, since it can't succeed long term; or that if we regain weight, it was our inevitable fate because of our "set point", not an outcome of choices: A rationalization, or excuse. I won't speak for you, but it seems as if for some of us humans, it's appealing to believe that unfavorable outcomes are not the result of choices one could've made differently, to get different outcomes.

    I think the reason set point theory gets me down so much is that implies the opposite: you could have avoided pushing your set point up if you had never made the choice to overreat in the first place (assuming you became obese in adulthood), but now its up you can't bring it down again. So yes, its your fault, and no, you can't do anything about it (any more).

    I advise depressed people not to talk to me! I will always find the worst case scenario! :smiley:

    Of course, I have met many people on here who have kept weight off for years, and I have read studies suggesting that even yo yo dieting is better for you than constant obesity, so I don't think all hope is lost. And after all, it's still just a theory.
