About this trial
This study will address the following aims:
Aim 1: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on body adiposity in adolescents with obesity.
Aim 1a (Primary): Evaluate intervention effectiveness on total fat mass following the 8-week intervention.
Hypothesis 1a: Adolescents randomized to the whole foods intervention will have lower total fat mass (kg) at the 8-week follow-up than those in the control group.
Aim 1b: Evaluate intervention effectiveness on anthropometric changes following the 8-week intervention.
Hypothesis 1b: Adolescents randomized to the whole foods intervention will have lower weight, BMI-z scores and/or waist circumference at the 8-week follow-up than those in the control group.
Secondary Aims:
Aim 2: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on diet quality in adolescent and parent pairs during the study period.
Hypothesis 2: Adolescents and parents randomized to the whole foods intervention will have higher diet quality scores at the 8-week follow-up than those in the control group.
Aim 3: Conduct post-intervention family focus groups to identify how individual/family needs and preferences and social determinants of health (SDOH) may be perceived barriers and/or facilitators of diet adherence to a whole foods diet pattern.
