Its probably pretty obvious that she has some mental issues, but from a healthcare workers standpoint I will share some quick hit thoughts on her fallacious reasoning.
-She "feels" better the bigger she gets. This one is solved a few lines down when she says "I actually started attracting more men." She doesn't actually feel healthier as the article (and she herself) implies. She merely feels wanted. Newsflash: Attracting men with a fat fetish =/= feeling "better."
-"I take my blood sugar like a diabetic." (emphasis mine). If you are taking your blood sugar, you have diabetes. This is one we get all the time in the ER. You ask someone if they have any previous medical problems, and they say no, and then they pull out a med list ten feet long. If you have medications or monitor for a disease process, you still have that disease, even if its well-controlled. Same goes with her blood pressure. Just because she is not dangerously hypertensive does not mean that its normal to check it every day after exercise and once a week just because. Obvious, but it still needs said. She is NOT healthy as she claims. An old medical saying; "Treat the patient, not the numbers."
-When the doctor says "I don't see any psychiatric problems" he means that there is not enough for them as medical staff to force a change of lifestyle on this women. The quote is taken out of context in this article and twisted to mean "she has nothing wrong with her mentally and emotionally." This is simply not true.
-She knows her time is limited. She insists that its healthy but then admits that reaching 1,600 pounds will be "pushing the limits." What limits? Her own dedication and eating ability? No. She assumes she will die before hitting that weight.
Being that fat, especially by choice, is not ok. She is on borrowed time. There is absolutely NO chance she will make her "goal" of weighing one ton. She is mentally unstable, and basically executing a slow-motion suicide plan.
