Best Fiber Supplements for Weight Loss

Can a spoonful of fiber double as a hunger zapper? Meet the unglamorous secret to feeling full (and skipping the snack run).

HUNGRY AFTER LUNCH AGAIN? You’re not alone — everyone’s been there: the 3 p.m. slump, the snack drawer calling your name. Fiber can help blunt that urge by bulking up your meals and slowing digestion. Simple, effective, and kind of boring in the best way.

Think of fiber as a quiet sidekick. Some types swell into a filling gel, others feed your gut bugs. Use them right and you get fewer cravings, steadier energy, and better regularity. No miracle, just smart, small wins.
