"I Let My Guard Down for a Moment, and Gained 11 kg"... Park Seo Jin Also Fell for This Habit's Warning [Health Talk]

[Financial News] Singer Park Seo Jin (30) recently drew attention after admitting on an entertainment program that he had gained 11 kg in five months after stopping his diet. He said, "I often ate Tanghulu and late-night snacks," explaining the reason for the sudden weight gain. As Park Seo Jin's case shows, once people return to high-calorie, high-sugar foods and late-night eating after an extreme diet, they can quickly regain weight and experience rebound weight gain, so caution is needed.
When people severely restrict their food intake for a long period during a diet, the body becomes more inclined to store energy. If they stop controlling their meals and start eating again during this period, the hormonal balance that regulates appetite can break down, leading them to eat more than usual.
In particular, the feeling of "I haven't been able to eat this before" can trigger a sense of compensation, which often leads to binge eating. At the same time, a body with a lower basal metabolic rate quickly stores incoming nutrients as fat, causing serious rebound weight gain.

High-sugar snacks such as Tanghulu, which people often reach for when they stop managing their weight, can have an immediate negative impact on health.
Excessive intake of simple sugars causes a rapid rise in blood sugar, known as a "blood sugar spike." To regulate this, the pancreas secretes too much insulin. When insulin levels in the blood rise, the process that converts excess sugar into body fat speeds up. If this high-sugar eating pattern continues, it can not only lead to weight gain but also cause insulin resistance, greatly increasing the risk of metabolic diseases such as diabetes.
Late-night snacking is also a major factor that can quickly increase body weight. Foods commonly chosen for late-night meals, such as fried chicken, pizza, and ramen, are mostly high in calories, fat, and sodium. When eaten at night, when activity levels are lower than during the day, they are not burned for energy and instead remain largely as body fat.
The harm caused by eating late at night goes beyond simple weight gain. If a person falls asleep before food is fully digested, the digestive system keeps working throughout the night instead of resting, which disrupts deep sleep and significantly lowers sleep quality.
Lying down with food still in the stomach is also a major cause of digestive disorders such as reflux esophagitis, gastritis, and chronic heartburn. If this late-night eating habit continues for a long time, blood cholesterol and triglyceride levels can rise sharply, further increasing the risk of adult diseases such as high blood pressure and hyperlipidemia.
Experts advise that "to maintain a healthy weight, it is important to follow a sustainable diet rather than extreme restriction" and that "people should avoid late-night snacks and high-sugar treats, and make it a habit to finish eating at least two to three hours before bedtime."
