Where do triglycerides come from?

Triglycerides: Triglycerides are the fat storage molecules your liver makes generally from sugars and excess calories that you eat. They thicken up the blood and can lead to blockages and damage to arteries.

Recent fatty meal: Most of the triglycerides represent recently-absorbed fat from a fatty meal. They will be broken down into the body's basic fuel, acetyl coa; if one takes in more calories than are needed for the day's energy production, the energy can be stored in the form of fat in the body. These steps are reversible; when more energy is needed, it can come from stored fat.
