The goal of the KD is to have participants achieve consistent blood BHB ≥0.5 mM; preferably in the range of >1 to 3 mM. We will measure ketones daily via finger stick to provide individual feedback and provide a quantitative measure of compliance. The KD will consist of approximately 50 g carbohydrate and 1.5 g/kg reference weight protein. These may be adjusted based on daily BHB readings. Fat will comprise the remaining calories with an emphasis on monounsaturated and saturated sources from whole foods. A wide range of foods will be incorporated including non-starchy vegetables, fruits (berries, olives, tomatoes, lemons/limes), meats (beef, chicken, pork, fish, lamb), nuts and seeds, oils (olive, canola, coconut), cheese, butter, cream, eggs, and fatty fish (salmon, sardines). Nutritional ketosis is associated with natriuresis that will lead to sodium and fluid loss if the extra sodium excreted is not compensated, thus slightly higher sodium and potassium intakes will be required.
The MD+PL arm will be modeled after a Mediterranean style eating pattern. It will contain the same amount of protein as the KD, but with slight variations in protein sources, including limiting red meat to 1x/wk. The diet will provide unprocessed, higher-fiber foods with emphasis on vegetables, fruits, nuts and seeds, legumes, tubers, whole grains, and fish and seafood. Poultry, eggs, cheese, and yogurt will be included in moderate amounts. Use of olive oil and other monounsaturated fat sources (e.g., avocados and olives) will be encouraged while keeping added sugars to a minimum and avoiding highly processed foods (refined grains, fruit juice, processed meats). Saturated fat will be <10% of energy. We will include adequate omega-3 fats (e.g., salmon). No alcohol will be included in both diets, but we will track consumption. This group will also consume two daily doses of placebo.
The MD+KE arm will consume the exact same diet as the MD+PL group with the exception they will consume two daily doses of KE instead of the placebo.
