Clinical Trial Summary

Introduction: Obesity is a major public health problem and adopting healthy lifestyle habits, while effective, is challenging in real-world settings. Culinary coaching is a behavioral intervention that aims to improve nutrition and overall health by facilitating home cooking through an active learning process that combines culinary training and health coaching. Our goal is to evaluate whether a culinary coaching telemedicine program (twelve 30-minute sessions) will significantly improve outcomes among subjects with overweight or obesity. General hypothesis: A culinary coaching telemedicine program will result in significant weight loss, and improvement in culinary attitude and self-efficacy, nutritional intake, and metabolic outcomes. Methods: This is a two-site, 36-month randomized controlled trial in which study participants between the ages of 25 to 70, with 27.5 ≤ BMI ≤ 35 Kg/m2 will be randomly assigned to nutritional counseling combined with a structured culinary coaching program or to nutritional counseling group (18 intervention, 18 control at each site). Intervention will include a 3-month culinary coaching telemedicine program with outcome data collected periodically for 12 months. The pre-defined primary outcome is body weight loss at 6 months, and secondary outcomes include change in body weight and composition at 1 year, as well as culinary attitudes and self-efficacy through a validated questionnaire, nutritional intake, lipid profile, blood pressure, and HgA1c (glycated hemoglobin); and participants' perception of the program. Potential impact: The investigators believe that this program has a potential to be a viable tool in promoting effective and scalable home cooking interventions aimed at improved nutrition and health outcomes in overweight and obesity.

Intervention

Behavioral:
CCTP
Twelve weekly one-on-one 30-minute tele-sessions through video conference. At the first session, subjects identify their vision regarding home cooking and 3-month goals. During each subsequent meeting, subjects will review their progress towards reaching the prior week's culinary goals and identify goals for the coming week, using a self-discovery process. When patients detect a new culinary skill that is necessary for their progress, s/he will either be taught through discussions or referred to active learning from a Culinary Resource Center.
Nutritional counseling
Two 30-minute nutritional counseling sessions

Outcome

Type Measure Description Time frame Safety issue
Primary Body weight at 6 months 5% decrease in body weight (kg) in the intervention arm as compared to control. measured by a registered dietitian. Six months
Secondary Body weight Body weight (kg), measured by a registered dietitian Body weight will be obtained at baseline, after the intervention (at 3 months), 6 months after the beginning of the intervention, and 12 months after the beginning of the intervention
Secondary Culinary attitude & self-efficacy Culinary attitudes and self-efficacy will be evaluated by the Cooking With a Chef (CWC) Instrument. This is a 22-item self-administered Likert scale questionnaire that generates three subscales: 1) the cooking techniques and meal preparation self-efficacy subscale (14 items; 1 - not al all confident; 5- extremely confident; sub-scale range 14-70), 2) the negative cooking attitudes subscale (4 items; 1 - strongly disagree; 5 - strongly agree; sub-scale range 4-20), and, 3) the self-efficacy to consume fruit and vegetables subscale (5 items; 1 - not al all confident; 5- extremely confident; sub-scale range 5-25). Culinary attitude & self-efficacy will be obtained at baseline, after the intervention (at 3 months), 6 months after the beginning of the intervention, and 12 months after the beginning of the intervention
Secondary Nutritional intake Nutritional intake will be evaluated by a 4-day food record. Intake will be analyzed for its caloric content (kcal), saturated fats(g), trans fats(g), legumes (g), fruits (g), red and processed meat (g), sugars(g), processed food(g), vegetables(g), soft drinks(g), fish(g), whole grain(g), refined grain(g), and monounsaturated fat-saturated fat ratio. Vegetables, legumes, fruits, nuts, whole grains, fish, monounsaturated fat-saturated fat ratio, alcohol, and meat will be aggregate to report Mediterranean index in points (1-9)) Nutritional intake will be obtained at baseline, after the intervention (at 3 months), 6 months after the beginning of the intervention, and 12 months after the beginning of the intervention
Secondary Adherence to Mediterranean Diet Adherence to Mediterranean Diet will be evaluated by the validated 14 items Questionnaire of Mediterranean Diet Adherence, extracted by a dietitian from a 4-day food record (0 - low adherence; 14 - high adherence) Nutritional intake will be obtained at baseline, after the intervention (at 3 months), 6 months after the beginning of the intervention, and 12 months after the beginning of the intervention
