Definition. The urine creatinine test measures the amount of creatinine in urine. Creatinine is a breakdown product of creatine, which is an important part of muscle. Creatinine is removed from the body entirely by the kidneys. Creatinine can also be measured by a blood test.
Ketones are the byproduct of breaking fatty acids down to be burned. Okay, it's a water fast, but we can assume that after 3 days, ketosis is acheived. About 250 grams of fat is about the maximum amount of fat that will be burned daily. I say around 250-300 grams per day.
To calculate your daily fat grams, multiply the number of calories you consume daily by 20 and 35 percent. This calculation yields your target fat calorie range. For a man or woman on a 2,000-calorie diet, the target fat-calorie range is 400 to 700 calories.Fat contains nine calories per gram, so divide each number of the fat-calorie range by nine to determine your daily fat grams. For a 2,000-calorie per day diet, the recommended daily fat intake is 44 to 78 grams.o calculate your daily fat grams, multiply the number of calories you consume daily by 20 and 35 percent. This calculation yields your target fat calorie range. For a man or woman on a 2,000-calorie diet, the target fat-calorie range is 400 to 700 calories.
