Experimenteel: MedDiet-WL
MedDiet-WL group, advice and exchange lists will be designed to promote a 1-2 lb. per week weight loss (approximately 30% caloric restriction or a reduction of about 600 calories per day) for an end goal of a 7% weight loss from baseline.
|
Research subjects will be randomly assigned to one of three intervention groups. The MedDiet-A group will learn about and how to adhere to the Mediterranean Diet. Over the course of 8 months, they will receive twenty-two classes 60-minute in length. The MedDiet-WL group will learn about the Mediterranean Diet, how to adhere to is and engage in lifestyle choices like exercising and eating fewer calories so that they will loose weight. Over the course of 8 months they will receive 22 classes, each 90 minutes in length. The Typical Diet Control group will be asked to maintain current eating and activity patterns over the course of the 14 month study. |
