What Makes Mukbang Stars Eat So Much? Doctors Weigh In

South Korean mukbang celebrities Tzuyang and Heebab recently revealed why they can consume enormous quantities of food, often shocking viewers with their eating abilities.

Medical examinations provided some clarity: both women have unusually large stomach capacities and extremely rapid metabolisms, making them capable of handling the vast amounts of food they eat during broadcasts.

During one segment, Heebab ate 14 rice servings in a single day before undergoing an X-ray. The results were astonishing—even the doctor had difficulty pinpointing her stomach because of how full it was.

“It was hard to locate the stomach due to its fullness. Her intestines had moved downward to allow for more room in the abdominal cavity,” the doctor noted.

This indicates that Heebab's stomach is extremely elastic and capable of expanding dramatically with each large meal she consumes.

According to Heebab, she typically has bowel movements three to four times daily, suggesting that her digestive system is constantly active and highly effective.

Doctors diagnosed her with an accelerated metabolism and superior digestive function, allowing her to manage and eliminate large meals quickly.

Tzuyang, too, underwent medical procedures and received similar feedback. Her stomach was measured to be significantly larger than the average, explaining her constant hunger and ability to eat in bulk without discomfort.
