Note: MLM = multilevel model; avg. = average; BMI = body mass index; stress impact = daily stress impact. All daily variables were averaged across the 49 days of data collection, and BMI was averaged across the 3 study assessments. Betas represent standardized effects. Effects significant at p <.01 are bolded.
