Study Arms:
- Diet A (low carbohydrate) (Type: EXPERIMENTAL): Dietary Intervention A will be a low-carbohydrate/high fat, ketogenic-type diet. The diet will include salads, leafy green and non-starchy vegetables, nuts and seeds, eggs, fish and shellfish, and meats in most meals. Grains and added sugars will be excluded, and starchy vegetables, fruits, berries, and legumes will be limited to below 10% of total calorie intake. In addition full fat yogurt, cheeses, and butter will be allowed in moderate amounts. Participants will be encouraged to eat freely from whole-foods rich in fats such as avocados, nuts, seeds, olives, coconut and to use coconut, medium-chain triglyceride (MCT), olive, and avocado oils for cooking and baking on that diet. Participants will aim to fulfill at least 65% of their total calorie requirements from fats.
- Diet B (low fat) (Type: EXPERIMENTAL): Dietary Intervention B will be low-fat, high carbohydrate whole-foods, plant-based diet. Most animal products and concentrated plant-based protein sources (such as soy isolates) will be excluded. Whole grains, particularly in their cooked form, legumes, vegetables, and fruits will be encouraged while excluding added sugars and refined grains. Added fats and oils will be discouraged on this diet as dietary fat should comprise less than 10% of total energy. Participants can eat freely from all types of fruits, vegetables, and cooked whole grains. Legumes will be emphasized as a replacement for meat and dairy products. Proteins similar to beef, pork, poultry, and dairy products, should be strictly limited, while lean proteins such as eggs, fish, and shellfish may be included occasionally.
- Diet C (USDA control) (Type: ACTIVE_COMPARATOR): The control dietary intervention will be based on the 2015 USDA Dietary Guidelines for Americans, with a slightly higher amount of protein than recommended for the general population, and will be comprised of grains (of which \~50% should be consumed as whole grains), 3 servings per day of non-fat or low-fat dairy, legumes, fruit, vegetables, fish, vegetable oils and margarines, and limited quantities of meat, eggs, added sugars, nuts/seeds. Participants will be encouraged to reduce sodium intake to less than 2300 mg (1500 mg for participants over 51 yrs. old) per day, and to consume less than 10% of calories from saturated fat.
