No, not shouting, emphasizing
" Clearly one who uses food or drink in such a way as to injure his health or impair the mental equipment needed for the discharge of his duties, is guilty of the sin of gluttony." OCE

But that is if it is consential, and knowing, and so- it could even be mortal sin, but is often accredited to psychological causes, and much of these cases probably need both prayer and a psychologist (I think it is largely psychological, but the original guilt may remain, in which case confession may be both aid and requirement in the matter)
for a look at some sources, it seems a sign of internal workings, fears, or desires, which are improportionate, but perhaps so from mental illness:
"In order to help us to understand the psychology of scruples it is important to make certain distinctions about the notion of guilt. There are really four types of guilt. First there is theological guilt. This is the condition of a person who has sciens volens violated the law of God. Secondly there is rational guilt. This is the condition of a person who has sciens volens violated the natural law, even though he does not explicitly advert to the element of transgression of the commandments or the law of God. Thirdly there is the condition of normal or healthy emotional guilt. This is the state of emotions, which is experienced when a reasonably balanced person, who is neither hardened to sin, nor pathologically cold, commits a serious sin or transgression of the moral order. It is perfectly healthy or normal for a youth, for example, to feel something of this if he commits a sin of impurity, or for an adult to feel this if he commits a serious violation of positive law. This is the state of feeling, which most people feel at some time or other in connection with confession. It is not itself “real” guilt, but is a natural concomitant of real guilt, and serves as an “indicator” that something is wrong in the moral order. Finally there is neurotic guilt. This is a complex state of the emotions, involving dread, anxiety, fear of punishment, desire for punishment, a sense of horror, depression, self-loathing, etc. It is neurotic if it is out of all proportion to the apparent cause, or if it exists without apparent cause, and is usually protracted through time and of such magnitude that it interferes with one’s normal adaptation, or produces physiological consequences (e.g., insomnia, loss of weight, morbid suicidal ideas, sweating, anorexia, gastric symptoms, etc.). "

In any case- it is complex, for instance, of gluttony, which is the sinfulness of disordinate eating Aquinas states:
"I answer that, Gluttony denotes, not any desire of eating and drinking, but an inordinate desire. Now desire is said to be inordinate through leaving the order of reason, wherein the good of moral virtue consists: and a thing is said to be a sin through being contrary to virtue. Wherefore it is evident that gluttony is a sin. "

And the encyclopedia says
“Gluttony
(From Lat. gluttire, to swallow, to gulp down), the excessive indulgence in food and drink. The moral deformity discernible in this vice lies in its defiance of the order postulated by reason, which prescribes necessity as the measure of indulgence in eating and drinking. This deordination, according to the teaching of the Angelic Doctor, may happen in five ways which are set forth in the scholastic verse: “Prae-propere, laute, nimis, ardenter, studiose” or, according to the apt rendering of Father Joseph Rickably: too soon, too expensively, too much, too eagerly, too daintily. Clearly one who uses food or drink in such a way as to injure his health or impair the mental equipment needed for the discharge of his duties, is guilty of the sin of gluttony.”
newadvent.org/cathen/06590a.htm
but as to anorexia, well, it is the result of other factors, yes- the body is the temple of the Holy Spirit, but, as with many things, we must not try to say that this is necessarily mortal sin, in that it is caused by psychological imbalances, but then again- all sin is insanity, but must be chosen and knowing insanity, to be mortal, and so we must question if this is consential, to even be venial sin, if not- then it is not sinful, but the workings of a unstable mentality, and word view.
The problem lies in generalization- the fear, anxiety, and wrong world view is itself sinful matter, and confession frees one from the forces that manifest in anorexic diseases, but there is also the purely psychological disease, which also needs curing- so- such people should see both confessor, and anyone qualified to aid them.
as the Summa state, but not of the gluttony (though this seems connected)-
"Yet in this case some might be excused from sin, when they do this not through vanity but on account of some contrary custom: although such a custom is not to be commended. " 169 modesty of outward apparel
newadvent.org/summa/3169.htm#article2
therein, their actions could fall also into sinful ideas, or vanity- but still, should not be commended-
rather- it should be seen by those who are to deal with these problems, and every effort should be made to end such disruptive temporary insanity- for to harm one’s own body s to act against sound reason, and therefore either slight insanity, or sin,
the guilt is not to be over or underestimated- rather- help must be given in conquering this often fatal disease, and part of such is grace, if it is their fault that they fell there, or even if it is not.
In the end, it is up to the confessor, the psychologist, and those involved to insure that the party receives the help needed, physical, spiritual (priestly aid, prayer, reason), and psychological.
