Teaching Kitchen Multisite Trial
Running, not enrolling · Not applicable
Conditions studied: Obesity
In brief
This TK-MT is an interactive year-long program that teaches culinary skills, nutrition education, mindfulness, and stress reduction, promotes movement, and optimizes behavior change through health coaching strategies. The purpose of this study is to test whether a referral-based teaching kitchen intervention offered for 12 months in adjunct to primary care obesity management is feasible, acceptable, and effective on improving health behaviors and obesity prevention. Specifically, the primary goal of the study is to provide evidence of improved behavior change (ex: increases in cooking at home, fruit and vegetable intake, exercise, sleep, mindful activities), improved lab values (ex: fasting blood glucose, cholesterol, triglycerides, etc.), and resulting change in body weight and waist circumference measures. The hypothesis is that by participating in this novel TK-MT intervention - learning to cook healthy, delicious, inexpensive meals at home; understanding principles of good nutrition (based on the Harvard Healthy Eating Plate); incorporating exercise more effectively into daily living; reducing stress and increasing mindfulness and sleep; and, having access to principles of health coaching - in order to leverage personal motivations - can provide a platform to transform individuals and consequently their health, not only for the duration of this study (16 weeks intensive, 8 months boosters for a total of 12 months) but for their entire lives.
