Will eating ponkan oranges at night make you gain weight?
Generally speaking, "lugan" refers to citrus fruits. Whether eating lukan at night leads to weight gain depends on specific circumstances. If discomfort occurs, it is recommended to seek medical advice promptly. The detailed analysis is as follows:

If the portion is controlled when eating lukan at night—consuming only 1–2 fruits—and the total daily caloric intake remains within a reasonable range with moderate physical activity, weight gain typically will not occur. Lukan has high water content and low calories, and contains dietary fiber that provides a certain degree of satiety. Eating a small amount can help relieve mild nighttime hunger without causing excessive calorie intake or placing undue metabolic strain on the body.
However, consuming large amounts of lukan at night—more than three fruits at once—or having already consumed many high-calorie foods during the day while lacking physical activity may lead to weight gain. Although lukan is low in calories, it does contain natural sugars. Excessive consumption may cause sugar to be converted into stored fat, potentially leading to weight increase over time. It may also加重 the digestive burden on the gastrointestinal tract at night.
When eating lukan at night, attention should be paid to controlling portion size, and it should be avoided within one hour before bedtime to prevent sleep disruption or gastrointestinal discomfort. Rinse your mouth after eating to prevent sugar residue from harming teeth. Maintaining a balanced diet and combining it with moderate exercise, rather than relying excessively on any single type of food, is key to maintaining stable body weight.
