When does gluttony constitute a serious sin?

[BornInMarch]

Obesity is an indication of a disease, not simply a moral fault of over-indulgence. Nobody wants to be fat.

To further complicate the mater, foods that cause obesity/excess weight actually cost LESS than healthy foods. Unlike in the past, impoverished people are often MORE likely to have excess weight simply because McDonalds is less expensive than Whole Foods.

Individual acts of overeating…intemperance (gluttony in this sense) are ordinarily venial matter for* venial *sin…(and one older moral manual even notes that such is even if one foresees it shortens ones life to some extent).

Can gluttony be grave (serious)? Yes - Such as when one is getting drunk where one looses ones reason (or if it leads to other mortal sins)…or when there uncorrected habits of eating in a way that will “seriously harm ones health or life” --at least in the “short term” that is…

But again individual acts of overeating are ordinarily venial sins.

Ones confessor can help in this…
