Eating that much food can cause the stomach to rupture or tear due to excessive stretching.
Eating a massive amount of food can also lead the stomach to expand and become distended, which can compress surrounding blood vessels as well as put pressure on the heart, raising the risk of cardiac arrest.
It can also cause a severe electrolyte imbalance, which can cause severe cardiac effects.
The appeal of mukbang videos originally began as a way to make people feel less lonely, especially when eating alone.
Dr Harris said: ‘While some studies suggest that watching mukbang videos can alleviate feelings of loneliness by providing a sense of social connection or companionship, others indicate that excessive consumption of these videos may exacerbate loneliness by substituting deeper real-life social interactions with more superficial virtual ones.’
But it has since become a grotesque display of gluttony and self-harm, according to registered dietitian Katie Lopez.
She told DailyMail.com: ‘Sadly, this is another example of the glorification of self-harming behavior.
‘More specifically, these people are at risk for stomach perforation, significant elevations in glucose and lipids, acid/base disorders, electrolyte shifts, dehydration, and heart rate abnormalities.’
Watching people gorge themselves on unhealthy foods can reinforce unhealthy eating habits, according to Dr Harris, who said the videos ‘centre around consumption and indulgence, potentially reinforcing a cycle of overeating or unhealthy food relationships.’
