アクティブコンパレータ:American Diabetes Association recommended diet
Participants in the American Diabetes Association (ADA) diet group will receive standard ADA advice.
The diet includes high-fiber foods (such as vegetables, fruits, whole grains, and legumes), low-fat dairy products, fresh fish, and foods low in saturated fat.
They will be asked to use the "plate method" to guide their nutritional choices.

実験的:Low Carbohydrate Diet
Participants will be instructed to follow a low carbohydrate, ketogenic diet: carbohydrate intake 20-35 grams a day not including fiber. Foods permitted include: meats, poultry, fish, eggs, cheese, cream, some nuts and seeds, green leafy vegetables, and most other non-starchy vegetables. Because most individuals self-limit caloric intake, no calorie restriction will be recommended. Participants will also be taught information about mindfulness and positive affect practices. The mindfulness-based curriculum will focus on the following elements: training on topics such as mindful meditation, mindful eating, awareness of fullness and hunger signals, and taste satiety. The positive emotion curriculum will include: training on topics such as noticing and savoring positive events, gratitude, positive reappraisal, personal strengths, attainable goals, and acts of kindness. |
