Self‐selected diet composition changes as predictors of short‐ (12 months) and long‐term (24 months) adherence to CR
REGRESSION
The variability in CR adherence is shown in Figure Distribution of adherence to calorie restriction (CR) at 12 (a, b) and 24‐month follow‐up visits (c, d) in the CR and ad libitum (AL) control groups. Percent calorie restriction (a, c) is shown with CR in gray and AL in green. Adherence for the CR participants are shown in (b, d), with adherence calculated as the natural log of the ratio of prescribed energy intake to total energy intake.We used mixture models to assess whether dietary composition affected adherence to CR. At the 12‐month time point, a null model was favored by AIC (AICAssociation between percentage reported energy from carbohydrate, fat, and protein at 12‐ and 24‐month follow up visits (a, c). Fitted trends are from linear regression to help interpret the sign of the association (coefficients not shown). Right‐angle mixture triangles at each time point (b, d) show the association between percentage reported energy from each macronutrient and adherence. Surface is as estimated by the AIC‐favored model. Red areas indicate high adherence, while blue areas indicate low adherence. Contours indicate the absolute value of adherence score.
