Metabolism is the process of ingesting nutrients and breaking them down for use by the body. We eat a doughnut in which the sugar water compounds are broken down into glucose, which goes into the muscles for us to consume when we exercise. The other part is stored by the liver as glycogen, which is used by the liver to maintain blood sugar in a reasonable range, and the rest of the energy is stored in the form of triglycerides in fat.
Fat can be thought of as a metabolic buffer that absorbs excess energy and stores it safely until it is released when needed. If we eat extra donuts, these calories are stored in our subcutaneous fat, and when we go on long hikes or swimming, a portion of that fat is released for the muscles.
When a person reaches the limit of their subcutaneous fat storage energy and continues to consume too many calories, the excess fat begins to spill over to the rest of your body: as excess triglycerides enter your bloodstream, enter your liver, cause non-alcoholic fatty liver disease, enter your muscle tissue, directly lead to muscle resistance to insulin, and even surround your heart and pancreas (pictured). Non-alcoholic fatty liver disease is just one of the many adverse consequences of this fat overflow.
Visceral fat cells secrete inflammatory cytokines such as TNF-alpha and IL-6, which are key markers of inflammation, and visceral fat increases the risk of cancer and cardiovascular disease.
Even if you only have a small amount of visceral fat, you are considered to be at very high risk for cardiovascular disease and type 2 diabetes, in the top 5% risk levels for your age and gender.
Non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD). NAFLD is the first stage and is caused by fat entering the liver in excess of excretion. The next step in deterioration is NASH, which is basically NAFLD plus inflammation.
If NASH is not controlled or reversed, it may progress to cirrhosis, metabolic dysfunction, and metabolic dysfunction greatly increases your risk of cardiovascular and cerebrovascular diseases, heart disease and Alzheimer's disease.
Metabolic syndrome is defined by five criteria:
1.Hypertension (> 130 85).
2.High triglycerides (>150 mg dl).
3.LDL cholesterol (< 40 mg dl for men or 50 mg dl < women).
4.Central obesity (waist circumference greater than 40 inches in men or greater than 35 inches in women).
5.Elevated fasting blood glucose (>110 mg dl).
If you meet three or more of the above criteria, you have metabolic syndrome.
We need to pay attention to the above routine indicators during physical examination, and the following two indicators are also important indicators of metabolic health:
1.NAFLD and NASH have no obvious symptoms and usually only show up in a blood test that examines the liver enzyme alanine aminotransferase (ALT). Elevated ALT levels are often the first important sign of a problem with the liver.
2.A DEXA scan can be done to check for visceral fat.
