Daily fiber needs: how much fiber should adults eat?

Fiber supports fullness, digestion, and overall diet quality. The practical target scales with calories, which makes it useful for both weight loss and maintenance plans.

Quick answer

A common adult fiber target is 14g fiber per 1,000 calories.

For a 2,000-calorie diet, that works out to about 28g fiber per day.

How Fit Crate uses this

If a meal plan is low in fullness or vegetables, Fit Crate can add fruit, vegetables, legumes, oats, or whole grains. Fiber should be increased gradually, especially for users who currently eat very little fiber.
