Back home in Sewanee. Tied my PR today on this course. Riding in between waves of severe thunderstorms. About 2 hrs ago I was falling into my PM nap and a tornado warning siren went off, woke me up. As usual, 'a hoax.' Another wave expected around sunset.
I hit it pretty hard and got to the turnaround by 5:00 flat. So I pushed it hard. Was unwilling to take the final downhill corner at breakneck speed so missed a PR.

MRICP is a biliary tree, common bile duct, pancreas and gallbladder exam which all can be altered by calorie and macro nutrient restriction. You should go into these tests with a normal baseline diet with a mix of proteins, fats and carbohydrates and NOT a calorie deficit. This is a potentially once in a lifetime excellent test and you risk biasing the results.
ReplyDeleteGoogle AI: Cutting out entire food groups or essential nutrients to an absolute zero. Examples include zero-carbohydrate diets or zero-fat diets.Because aMRCP scan specifically looks at the biliary system, a zero-fat diet is particularly extreme. Without fat, the gallbladder never gets the hormonal signal to contract and empty its bile, directly causing the stagnant bile sludge and gallstones that show up on your scan. Depriving the liver of glycogen and shifting metabolic processes can lead to rapid changes in fluid balance and tissue hydration. These physiological shifts may influence the appearance of organs and fluids on an MRI, potentially complicating the interpretation of the scan.If an MRCP has been scheduled, it is generally recommended to maintain a stable and balanced eating pattern leading up to the appointment to ensure the results reflect a typical physiological state. Any significant dietary changes or recent periods of restriction should be discussed with the ordering physician.
ReplyDeleteThis is not unlike previous tests that you did extended fasts for. For the bizzillionth time tests and exams have been developed on normal people with normal diets , diets and exercise at the end of the distribution can bias the results or make for a interpretation that doesn’t reflect baseline. You should have just chilled the last couple of days, had some toast with jam, a moderate amount of fat and carbs, and NOT have been in calorie deficit. You know, like a normal person and not some one who travels with an impedance scale to measure body fat
ReplyDeleteI've been eating pretty much as I am now for weeks. Supposed to fast 4-6 hrs before scan, including water. I've eaten some fat this week, avocados, a piece of chocolate, sardines.
