What is fiber?

Dietary fiber is the indigestible part of plant foods that supports gut health, satiety, and blood sugar control. It aids digestion and long-term health while supporting diet adherence.

How does it work?

Soluble fiber slows digestion and stabilizes glucose; insoluble adds bulk for regularity. Fiber feeds gut microbes, producing short-chain fatty acids that support gut lining and metabolic health. It increases fullness, helping maintain calorie targets during cuts.

Practical application

Include vegetables at most meals, 2-3 fruits daily, and some whole grains/legumes. Increase fiber gradually and hydrate to avoid GI distress. Time high-fiber meals away from immediate pre-lift windows to prevent bloating. Track tolerance; some sources (beans, certain veggies) may require portion tweaks.

  • Target10-15 g/1,000 kcal; increase slowly.
  • SourcesMix fruit, vegetables, legumes, whole grains, nuts/seeds.
  • TimingKeep very high-fiber meals away from pre-lift if they cause discomfort.

Common mistakes

  • Jumping fiber intake too fast, causing bloating.
  • Ignoring water intake when increasing fiber.
  • Over-relying on supplements instead of varied whole-food sources.
