The term "carb face" has sparked controversy on Chinese social media, with many criticizing it for turning normal eating habits into a source of appearance anxiety.
On short-video platforms, some influencers blame carbohydrates for fuller faces, while others celebrate sharper jawlines after cutting carbs. The trend has also fueled the marketing of anti-sugar supplements and meal replacements, reinforcing the idea that "carbs equal ugliness and lack of self-discipline".
The national dietary guidelines recommend that carbohydrates provide 50 to 65 percent of daily energy intake.
Experts note that carbohydrates are essential nutrients and that high-quality carbs such as whole grains, beans, potatoes and fruits play an important role in health and weight management.
By contrast, foods such as chips, cakes and sugary drinks are considered low-quality carbs because of their high sugar, salt or fat content.
While some online discussions label refined rice and flour products as "bad carbohydrates", nutritionists note that they are easier to digest and may be better suited to people with sensitive stomachs, stressing that a balanced diet remains the healthiest approach.
