Consumption of takeaway and delivery meals is associated with increased BMI and percent fat among UK Biobank participants.

Homecooked meals were more often consumed by those with low BMI and percent body fat, whereas delivery and takeaway meals were more often eaten by individuals with higher BMI. Consumption of fast-food/café meals was not consistently associated with BMI or percent body fat. The direction of causality in these associations cannot be inferred from this cross-sectional study.
