We never repent of having eaten too little.

The saying expresses a moral of moderation: overindulgence commonly brings discomfort or regret, while restraint rarely does. Cast as a universal “we,” it turns private bodily experience into a general rule of conduct—suggesting that self-control is a safer default than excess. In quotation culture it is often grouped with aphorisms about temperance, health, and prudence, and it can be read both literally (dietary moderation) and figuratively (avoiding excess in pleasures, spending, or appetites of any kind).
