If I understand correctly, Shangri La theory regarding setpoints says that the setpoint is like a thermostat, and it goes up and down throughout the day, depending on whether and what you are eating.
How would you interpret the experience of someone who loses, say fifty or more pounds (either through SLD or conventional diet), and then regains, going back up to virtually the exact weight she had before the diet? Was she able to lose all that weight without changing the setpoint? If she did change the setpoint in order to lose weight, how did the body know how much weight to regain?
Is there a fluctuating setpoint that moves up and down throughout the day and another setpoint that is harder to change permanently?
Does Shangri La really change/lower the setpoint, or is it suppressing the setpoint for as long as the dieter is taking flavorless calories (or eating bland foods, crazy spicing, etc)?
If not eating lowers the setpoint, what does fasting do to it, either for an extended period (say 1-6 weeks) or for shorter, more frequent periods (say 36-72 hours)? I know there are a lot of people here who fast for a portion of the day, but I am wondering if anyone has tried a longer fast.
Sorry for all the questions, but I can't quite grasp how this works, and I am hoping that if I can understand it before I lose weight, then maybe I can avoid losing a bunch of weight and gaining it right back again. Thanks!
