P<0.05.

Each model controlled for age, sex, ethnicity, SES and physical activity.

The value of the R² shows the proportion of the variance in BMI or that could be explained by all the variables included in the model.

The value of the partial R² shows the proportion of the variance in WC that could be explained by the meat and/or VF or grain variables included in the model.
