Therefore here lieth all the mastery and skill to be able to distinguish wisely need from lust and voluntary liking, being so knit together that the one cometh with the other. So that it is hard to take the one (which is the meat or drink) as need requireth, and to reject or not to admit the other, namely, the voluntary and willingly admitted lust and liking, which often cometh under the colour of need.(John Climacus)

How should I distinguish need from voluntary liking? I have not read ahead.

The implication is that if I enjoy something I need - such as food, drink, or clothing - I am edging toward sin.

The Latin word from which glutton is derived means to gulp, to swallow without tasting. The glutton does not enjoy. The glutton is obsessed, which is entirely different.

I am reacting so strongly that I will need to give particular care to the advice Climacus offers.

I do not doubt the problem of gluttony and other aspects of over-consumption, but I tend to see the source as insatiability rather than sensuality.

The image is from an allegory of gluttony by Hieronymus Bosch.
