Diets, like clothes, should be tailored to you.

The line uses a fashion metaphor—one of Rivers’s signature comedic terrains—to argue against one-size-fits-all prescriptions. By comparing diets to clothing that must be “tailored,” it suggests that bodies, lifestyles, health needs, and preferences vary, so any eating plan should be individualized rather than adopted as a trend. The quip also lightly punctures the diet industry’s promise of universal solutions, implying that what “fits” (and is sustainable) depends on the person. In Rivers’s broader persona, the joke doubles as social commentary: modern culture polices bodies while selling quick fixes, yet genuine well-being requires personal fit and realism rather than conformity.
