Viral TikTok Trend: 'Mouthful Diet' Sees Users Chewing Food and Spitting It Out

A new, concerning weight loss trend has gone viral on social media, originating in China. The method involves chewing food and then discarding it without swallowing, using plastic wrap or a bag in the mouth. The logic behind this practice is to taste the food without consuming calories, with the belief that the brain will feel satisfied. However, experts point out that there is no scientific basis for this method and that it can be dangerous, causing choking, plastic ingestion, or reinforcing disordered eating behaviors. This trend reflects an unhealthy obsession with weight loss and a distorted relationship with food.
