Quick Answer (TL;DR)
Constant hunger has many causes—not just "lack of willpower":
- Satiety = the feeling of fullness after eating. It's influenced by fiber, protein, water, meal timing, and hormones.
- Fiber (like glucomannan) may help you feel fuller longer by absorbing water and expanding in your stomach [1].
- But: No single ingredient "stops hunger completely" or guarantees weight loss.
- Best approach: Balanced meals + adequate protein + hydration + sleep + activity.
Who Should See a Doctor
- Hunger that doesn't go away even after eating
- Unexplained weight changes (gain or loss)
- Excessive thirst combined with hunger (could signal diabetes)
- Mood changes or anxiety around food
These may indicate underlying conditions. Consult a clinician.
