Fiber Is the Carb You Are Skipping

Fiber is not technically digested in the way starch and sugar are, but it is the most underrated component of any diet. Soluble fiber slows digestion, blunts blood-sugar spikes, and feeds the gut bacteria that influence everything from mood to immunity. Insoluble fiber keeps things moving and reduces hunger by adding bulk to meals.

The target most adults should hit is thirty to forty grams a day. The actual average sits closer to fifteen. Closing that gap improves digestion within a week and reduces snack-driven hunger within two.

The sources are unglamorous and effective: oats, beans, lentils, vegetables, fruit, whole grains, and seeds. If you are coming from a low-fiber baseline, ramp up gradually over two weeks to avoid digestive complaints. Drink more water as you do. The benefit shows up everywhere, appetite, energy, training, sleep.
