I personally believe that the 'setpoint theory' may be true. That is, your body knows the weight it wants to be and will eventually 'defend' that weight when more than 10-15 pounds is lost. It 'gets the weight back' by means of ramping up hunger and ramping down satiety.
THAT SAID - and this may go to your question - it doesn't appear that disordered eaters have any idea what tneir setpoint is until they reach the point where they're eating intuitively and thereby give their body the opportunity to 'find it's weight.'
Some people, I'm sure, are under-eating. And I'm equally confident that others are overeating.
Ex: a recent client of mine was an acknowledged stress-eater. As soon as he got a handle on that he: (1) likely stemmed future weight gain and (2) lost about fifteen pounds and settled in there. In his case, he lost weight more or less accidentally. Others are likely to gain some weight at which point they let go and give themselves permission to savor the foods they enjoy, eating when hungry and stopping when satisfied.
I myself no longer invite people to lose weight or gain weight.
Unable to maintain weight loss/gain. Eating disorder. And what I can imagine "set point theory" is...
In my opinion... 98% mental inability, 2% physical inability.
I recognized that there exists REAL physical limitations.
That said, there is a reason a person's day may go like this:
Breakfast: 2x toaster waffle with syrup and butter, glass of OJ
9-10 AM: Bagel with cream cheese, coffee with easily 10% of the cup volume sugar, 10% cup volume half/half
Lunch: Wendy's dollar menu: 2x jr bacon cheeseburger, fries, frosty
Afternoon: Snickers with a 20oz coke.
Dinner: A couple of slices of pizza and a coke.
Snack: Ice Cream
MENTALLY INEPT to realize that the calories ingested FAR EXCEEDS what is needed to sustain 200 lb, far exceeds what is needed to sustain a current weight of 260 lb, and is probably what is required for 325 lb.
Realizes all the above, and either chooses to not care (mental) or does it because he knows that he can try to change the habits but just fall back into them after a few weeks (not mentally strong enough).
I wish I could tell you that I made up that scenario... but, that was me, a long time ago.
