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, if you aim to eat 2,000 calories per day, your daily allowance of saturated fat would be less than 10 percent of 2,000 calories or 200 calories. There are approximately 9 calories in a gram of fat. OK, OK. To make the math easier, weâll use 10 calories per gram of fat.or example, if you aim to eat 2,000 calories per day, your daily allowance of saturated fat would be less than 10 percent of 2,000 calories or 200 calories.
