Feasibility of a Carbohydrate-restricted, High-fat Diet on Head and Neck Squamous Cell Carcinoma Outcomes

"Diet composition was \~45% fats, \~30% carbohydrates, and \~25% proteins. Calorie needs were provided according to what the Bioelectrical Impedance (BIA) device gave as required to maintain bodyweight.~Sources of macronutrients:~* Carbohydrates: from whole grains, dairy products, legumes, fruits, and vegetables.~* Fats: from mono- and polyunsaturated fatty acids, including medium- and long-chain fatty acids.~* Proteins: plant-based proteins and lean animal-based proteins. All meals were provided to the participants throughout the study period and the diet was provided orally unless the patient was on a feeding tube or a feeding tube is ordered by a physician during the study period. Diet texture was according to patients chewing and swallowing abilities. If the patient is on a feeding tube or intake is insufficient, a formula with similar macronutrient composition + a protein supplement was provided."

The regular composition diet contained approximately 50-52% carbohydrates, 30% fats, and 18-20% proteins
