why am i still hungry after eating

The main reasons for still feeling hungry after eating relate to meal size and composition, hormonal signals, and lifestyle factors. Often, this occurs because the meal did not contain enough calories or key nutrients like protein, fiber, or healthy fats, which are essential for signaling fullness effectively. Meals rich in protein and fiber help slow digestion and stimulate hormones that promote satiety, such as leptin, cholecystokinin (CCK), GLP-1, and peptide YY (PYY). Additionally, rapid changes in blood sugar levels from meals high in simple carbohydrates or processed foods can lead to quick hunger recurrence. Other reasons may include hormonal imbalances, insufficient calorie intake throughout the day, or lifestyle factors like stress or lack of sleep that influence hunger signals. Eating balanced meals with adequate protein, fiber, and healthy fats, and maintaining consistent calorie intake, can help reduce persistent hunger after eating.
