Constant hunger is not always a simple signal to “eat more.” It can reflect blood sugar swings and insulin imbalance. Feeling hungry soon after refined carbohydrate-heavy meals may relate to reactive hypoglycemia patterns or insulin resistance. Low protein/fiber intake, poor sleep, chronic stress, and certain thyroid issues can also increase appetite. The key is the type of hunger: true physical hunger versus cravings focused on sweets and snacks. A practical strategy is to structure meals with adequate protein and fiber, remove sugary drinks, restore sleep, and consider lab evaluation to assess metabolic status. If persistent, an internal medicine evaluation helps identify the underlying driver and build a targeted plan.
