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.
How do you know if youâve had 10 percent of your calories from saturated fats? The best way is to calculate 10 percent of your daily calories and then translate that into fat grams. For example, if you consume 1500 calories a day, 150 calories can come from saturated fat. There are 9 calories per gram of fat, so dividing 150 by 9 that equates to around 17 grams of saturated fat.
