My question and an answer I found from Gwyneth Olwyn about set point weight I think fit.

I wanted to ask a question because I could not find it on eatopia. But  later I found an answer on a pretty similar question. This is my question: 

According to youreatiopia we have a set point weight so we don't have to worry about gaining and gaining in recovery, but what about the fact that i gained in my teens before the anorexia when i ate candy every day and junk food? I wonder if I will be as big as then when i have recovered. Cause the set point theory says my set point should regulate so that I should not gain even though I ate more, so even though I gained weight at 16 was it not because of the bad diet/comfort eating? Was my weight the weight my body wanted then and also want for me now? Will I be as big as then even though i eat more healthy now in recovery? 

To become thinner than your body is natural meant to be (at your setpoint) then you have to restrict and that is uncomfortable and miserable would you not agree? You are eating less than you want and need, all of the time, and it hurts physically and mentally to do this. So to become heavier than your natural setpoint, you would have to eat more than you want, all of the time, and eat so that you mentally and physically do not want any more but still go on eating, to the point of being sick and miserable and in pain.  With the exception of people who have binge eating disorder, people just do not do this. (BED is however frequently misdiagnosed in those in recovery from REDs when the person recovering is clearly experiencing reactive eating or extreme hunger). Other than these circumstances, and those that suffer from Prada-Willi syndrome, people do not keep eating when they do not want to, when they mentally or physically do not have any inclination to eat, and are suffering if they eat more. Unfortunately, because of restrictive eating disorders, and the way that society is, people will suffer like this for the opposite effect of becoming underweight for their own body.

BMI is more accurate on the lower end because being underweight is not natural nor is it healthy (although there is a tiny percentage of people that are naturally on the very low end of a healthy BMI, yes). It is pretty obvious that restricting is going to cause problems when your body and mind are telling you to eat and you ignore it. The upper end of the BMI system is a load of crap because it has been adjusted to fit our society. Did you know that in 1998, the National Institutes of Health lowered the overweight threshold from BMI 27.8 to 25? The move added 30 million Americans who were previously in the “healthy weight” category to the “overweight” category.

The only way you go below your setpoint is to make yourself miserable by starving. The only way to go above your setpoint is to make yourself miserable by over-eating. If anyone is eating however much and enjoying the food, then that is healthy. If they are in pain and forcing it in to the point of suffering, then yeah, I’m sure you can go over your setpoint. But who do you know who does that on a regular occasion (unless you know someone with BED)?
