Online eating shows originated in South Korea and have gained popularity     1     ( global).

Many hosts of such shows become popular for their ability to eat large    2    (amount) of food. But these shows have also received criticism for their waste of food. While some hosts actually do consume the amount of food    3     (show), others may be faking(假装)     4    .

To discourage this practice, many video and livestreaming (直播)platforms have removed videos     5    show food waste and have promoted (宣传)messages to stop food waste and eat reasonably.
