Interventions
Ketone Ester Acute
Participants will undertake a controlled feeding intervention where they will consume 25g of C8 Ketone Diester with a meal, and images obtained before and after consumption. The supplement powder contains 12.5 g C8 Diester, sodium caseinate and soluble corn fiber, per serving. The powder contains 120 kcal, 0 g fat, 3 g carbohydrate, and 0 g protein. A standardized meal will be provided to subjects to consume with their allocated supplement during the MRI visits. This meal is formulated with whole foods (i.e. chicken, rice, and a fruit bar) as a mix of macronutrients (29% protein, 3% fat, and 68% carbohydrate - not including the supplements). The meal consists of \~700kcal of food and will be standardized between all visits and subjects.
Placebo Acute
Participants will undertake a controlled feeding intervention where they will drink two servings of the placebo with a meal, and images obtained before and after consumption. The placebo is flavor, energy, volume, and macronutrient matched will be given to patients as part of the placebo arm of the study. This placebo will not contain any BHB, which will be replaced with a similar caloric content of fat in the form of canola oil.
