Why don't I lose weight even though I feel hungry every day?

Under normal circumstances, feeling hungry every day without losing weight is generally related to improper dietary structure, excessive water intake, increased muscle mass, slowed metabolism, and hidden calorie intake. A detailed analysis is as follows:

1. Improper dietary structure: Consuming large amounts of high-fat and high-sugar foods when hungry may not reduce total calorie intake—in fact, it may exceed the body's consumption. Excess calories are converted into stored fat, leading to no decrease in body weight despite hunger.

2. Excessive water intake: Drinking large amounts of water in a short time may cause temporary water retention in the body, making body weight remain stable or even increase temporarily. Even with hunger, weight loss won't be observed until the excess water is expelled.

3. Increased muscle mass: Consistent exercise might reduce body fat while increasing muscle mass. Since muscle density is greater than that of fat, body weight may show little change. Despite frequent hunger, body shape may appear more toned.

4. Slowed metabolism: Prolonged insufficient calorie intake may cause the body to enter an energy-saving mode, reducing metabolic rate and calorie expenditure. Even with frequent hunger, if the body burns fewer calories than consumed, weight loss will be difficult.

5. Hidden calorie intake: Some people eat large amounts of snacks or drink calorie-dense beverages when hungry. These foods may appear small in quantity but contain high calories. Accumulated over time, they exceed total calorie requirements, causing hunger to persist without weight loss.

When this situation occurs, it is recommended to adjust the dietary structure by reducing high-sugar and high-fat foods, ensuring adequate protein and dietary fiber intake, exercising regularly, and controlling hidden calories. If this persists long-term or is accompanied by other discomforts, a medical evaluation should be sought promptly.
