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.
For example, the Daily Value for fat, based on a 2,000-calorie diet, is 65 grams (g). A food that has 13 g of fat per serving would state on the label that the percent Daily Value for fat is 20 percent.or example a food label may say 12g of fat = 18% daily value. This means that 12 grams of fat is 18% of the total 65 grams of fat recommended per day. You can use the percentage to decide if there is a low or high amount of that particular nutrient in one serving of the product. Low = 5% or less.
