TriglyceridesTG
The main form of fat carried in your blood.
Triglycerides are the most common type of fat in the body and in the bloodstream. They come both from the fat in food and from the liver, which turns excess energy — particularly from refined carbohydrate and alcohol — into triglycerides for storage.
They matter because raised blood triglycerides often travel with insulin resistance and low HDL cholesterol, forming part of the cluster behind metabolic syndrome and adding to cardiovascular risk. They are one of the more diet-responsive blood markers.
In practice, triglycerides are measured as part of a standard lipid panel and read alongside HDL and LDL; they tend to fall with fewer excess calories, less refined carbohydrate and alcohol, and more regular exercise.
