Franklin presents dietary moderation as a way of promoting a longer life. The saying reflects a long-standing belief that excessive eating can damage health, while restraint may help preserve it. By linking smaller meals with longevity, he turns moderation into a practical rule for everyday conduct.

The maxim should not be read as a precise medical prescription or as evidence that simply eating less will extend every person’s life. Modern health depends on factors including nutrition, illness, genetics and overall lifestyle. Franklin’s broader point is that excess can carry physical costs and that moderation may support wellbeing. The saying therefore belongs to a tradition of practical health advice that values restraint, while its specific claim about longevity is better understood as an historical generalisation than a universal medical rule.
