Treatment and study plan

Green Chef Meal Delivery Program

Dietary Supplement

Participants will receive Green Chef meals for lunch and dinner, delivered weekly for 16 weeks. Meals include organic produce, responsibly sourced protein, and nutritionist-approved recipes. Participants will also receive guidelines for preparing healthy breakfasts and will use smart devices to record biomarker data.

Primary outcomes

  1. Change in Blood Lipid Biomarkers (LDL, HDL, Triglycerides)

    Time frame: Baseline to Week 16

    Blood lipid levels (LDL, HDL, triglycerides) will be measured at baseline and week 16 via fasting blood draws to evaluate the effect of the Green Chef meal plan on cardiovascular health.

  2. Change in Weight and Body Composition

    Time frame: Baseline, Week 8, Week 16

    Body weight and composition will be measured using a Withings smart scale at baseline, week 8, and week 16 to assess changes related to the dietary intervention.

  3. Change in Blood Pressure

    Time frame: Baseline, Week 8, Week 16

    Systolic and diastolic blood pressure will be measured using a Withings smart blood pressure cuff at baseline, week 8, and week 16 to assess impact of the meal plan on cardiovascular function.

Secondary outcomes

  1. Change in Self-Reported Health Perceptions

    Time frame: Baseline, Week 4, Week 8, Week 12, Week 16
