The Claim
In Chinese adolescents aged 17–22 years, females have a higher body fat percentage than males, and males have a higher visceral fat area than females.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among Chinese adolescents aged 17 to 22, females have more body fat than males, and males have more visceral fat than females.
See the scientific wording
In Chinese adolescents aged 17–22 years, body fat percentage is significantly higher in females than males (20.00% vs. 31.72%), and males have higher visceral fat area (70.96 cm² vs. 56.33 cm²), indicating sex-specific patterns in fat distribution that may influence obesity risk.
When teens sleep too little or at irregular times, their body produces less of a hormone that tells them they're full and more of a hormone that makes them hungry. This causes them to eat more, especially late at night, and their body stores more fat. In girls, this leads to more fat all over the body. In boys, the same disruption causes fat to build up deep inside the belly around organs. This happens because the body's internal clock gets thrown off, which changes how fat cells work and how the body uses energy.
What the research says
1 studyThe study found that poor sleep makes teens store more fat around the belly and overall, and since boys and girls often sleep differently, this helps explain why girls tend to have more total body fat while boys have more belly fat.
