How Fiber Supports Digestion and Weight Loss Naturally
Fiber is often overlooked, but it plays a powerful role in maintaining a healthy gut and a balanced weight. Found in fruits, vegetables, whole grains, and legumes, fiber helps your body digest food efficiently while keeping you full longer.
There are two main types:
-
Soluble fiber dissolves in water and helps regulate blood sugar and cholesterol.
-
Insoluble fiber adds bulk to stool and supports regular bowel movements.
Together, they make fiber a digestion hero—and a secret weapon for weight loss.
