http://fnic.nal.usda.gov/fnic/interactiveDRI/index.phpHere is a link from the USDA for Health Care Professionals containing an "Interactive Dietary Reference Intake" by age, gender, activity. There are daily intake requirement Guidlines for oncocology patients too, who may have metabolic changes from the tumor itself, surgery, radiation, chemo that may increase Resting Energy Expenditure(REE), so the daily intake may be more. Head and neck patients may be more malnourished for these, and other reasons, but more in extreme excess is not good either since excess nutrients can feed cancer, and excess protein puts a burden on the kidneys due to them emliminating the Ketones in the urine, which may also contribute to dehydration, so if more protein is needed, so should the water.
The input for my age, 51, height 5'10" 180 lbs, and a sedentary lifestyle, showed I need the below daily requirements, but other input is not included, like tumor, type of chemo to flush out kidneys, etc. Its nor far off from another calculator for water, which comes to about 1/2 your body weight in ounces. Mine was 90, plus more from food. I also read elsewhere that 80 percent of your water need should be liquid by mouth, and 20 percent by food for cancer patients.
Caloroes: 2438
Protein: 65g
Fat: 54-95g
Carbohydrate: 274-396g
Total Water: 3.7 liters (about 16 cups = 128 ounces)
I hope this helps
