In plain English

People who eat more ultra-processed foods have a higher average body mass index than those who eat less, with the highest consumers averaging 25.91 kg/m² compared to 25.30 kg/m² overall.

See the scientific wording

Higher consumption of ultra-processed foods is associated with higher body mass index, with individuals in the highest UPF intake group having a mean BMI of 25.91 kg/m² compared to 25.30 kg/m² in the overall sample, suggesting a link between UPF intake and weight status in this population.

Why this might work

Eating more ultra-processed foods delivers more calories in smaller volumes, making it easier to consume more energy than the body needs. These foods also do not trigger fullness signals as strongly as whole foods, so people keep eating. The extra calories get stored as fat, increasing body weight over time.
