De: It is mainly the "Rat Poison" which deregulates homeostasis in the human body which constitutes the main problem with gaining weight. Without Rat Poison, the vast majority of humans would find it very unappealing to eat enough calories to gain, and keep, a lot of extra weight. So I wouldn't fear "eating" to fullness, at all; You mainly need to avoid any Rat Poison and the body will gradually begin to lose weight (absent onset of metabolic diseases which can take on a life of their own with a 'brain' of its own).
Also, as you probably, know:
(1) When losing weight quickly, dehydration tends to constitute a signficant portion of the weight loss; so you hare hopefully drinking lots and lots of water?
(2) Almost everyone who loses weight quickly gains it all back, and typically MORE, when they get tired of the "diet". The body was DESIGNED to handle a famine and feast availability of food. You can't easily outsmart it nor "out will" it for very long.
I consider it important to have rules of engagement for how much, and when, you are allowed to break from the diet. Otherwise it becomes a willpower issue: like holding your breath indefinitely by will power. You will always lose that game after a predictable limit.
If you want to change something that physiologically programmed you need to be wise about it. Go SLOWLY. Have those rules I mentioned. Ideally, BECOME A DIFFERNT PERSON AT A SIGNIFICANTLY DEEP ENOUGH LEVEL. At an IDENTITY level, or even above that. E.G., http://www.skillsyouneed.com/lead/logical-levels.html
P.S. Actually, the article said one thing slightly incorrect: Dilts didn't originate this, although he put them into that neat format. The great Anthropologist Gregory Bateson discussed the hierarchy previously. And you see a sketch of this sort of thinking going back to earlier psychologists and Maslow (Hierarchy of Needs).
Indeed, "Men are anxious to change their circumstances, but are unwilling to change themselves. They, therefore, remain bound." -James Allen (1902)_As _a_Man_Thinketh. And probably William James himself was well aware of the basic hierarchy.
