About the Path way of the Fat from the mouth to the Fat tissues and the consequences of that.
The Fat enters the Mouth --> Oesophagus --> Stomach (Gaster Ventriculus) --> Duodenum. Here the Fat come in contact with enzyme Lipase from the pancreatic juice that make possible to the Fat (Lipids) to be absorbed from the intestine ( the gut). The absorptions process is a little complicated and will bore the reader's. In the endothelial cells off the intestine, the Lipids molecules are converted to Chylomicrons, a small fat droplets (diameter 1 micron.), This Chylomicrons are collected by the lymph rather than by the blood. The Carbs , the Proteins and an little part speciality off Lipids are collected by the blood and flow trough the Vena Porta into the liver. This complex of lymph vessel has the name Chylus vessel's. All this small lymph vessel end in the termination vessel (Thoracic Duct, Google the name in English Wikipedia) and are then transported upward and are emptied in the circulated venous blood in the Subclavian vein that enter the Vena Cava Superior in front of the Heart. After that this fat droplets , the Chylomicrons, are transported in the right heart atrium and in the right ventricle. From there they are pumped in the lungs and go back in the Heart in the left atrium and in the left ventricle and finally are pumped in the Aorta. Hereby all parts of the heart and the lungs are lubricated with this particles. After the Aorta continue the lubrication of all arteries and veins in the organism, until all of this particles are absorbed by the liver , Adipose tissues (Fat tissues) and another tissues.
The description of this process has been much simplified, but it give a clean picture of this process.
The LCHF diet after absorption in the gut results with to much chylomicrons in the blood , that are a lipoproteins. To be removed all this chylomicrons from the blood vessels, it take time . In meantime this lipoproteins together with another lipoproteins in the blood are a risk factors for Atherosclerosis. Its complication include coronary heart disease (CHD), acute Myocardial Infarction, strokes and some form of senile Dementia. The important risk factors of atherosclerosis and CHD are AGE's ( Advanced Glycosylated End products), the male gender, smoking, Diabetes Mellitus (DM) and another as I do not remember for the moment.
This huge injection off FAT in the front of the Heart can be compared with the Oil injection under the piston by the 4-stroke gasoline engines. This oil injection lubricate the piston and the cylinder. This is what happen if the person eating to much Fat.
The characteristic lesion of the atherosclerosis is the Atheromatous plaque in the large arteries Tunica Intima ( the arteries has three layer, the inner layer Tunica Intima, In the middle is Tunica Media and the outer layer Tunica Adventitia).
A typical plaques contain a core of cholesterol and is surrounded by an area of fibrosis.
As the person with T2DM there is a great probability to get this problems.
As reader, think about the hypothetical experiment with the two pipe's and the
4-stroke gasoline engines. If some fill more oil in the engine , then the engine get problems as plaque off burned oil on the surface on many parts of the engine. Such is by the human's organism.
