Feeling very hungry can stem from several factors. Common reasons include not eating enough protein, fiber, or healthy fats which help keep you full; eating too quickly so your body doesn't register fullness in time; stress and lack of sleep which affect hunger hormones; dehydration mistaken for hunger; and certain medications or health conditions like diabetes or thyroid problems. Sometimes hunger is psychological, driven by emotions rather than actual need for food. Drinking water, balanced meals with adequate protein and fiber, managing stress, and getting enough sleep can help reduce excessive hunger. If hunger persists without clear reason, it might be worth consulting a healthcare provider to rule out medical causes.
