Triglycerides are deposits of fat that are present in the body and they are linked to the amount of carbohydrates you are eating. When you consume carbohydrates (bread, pasta, cereals, fruits and vegetables) your body uses them to make glucose, which is food for your cells. They take what they need, and any excess glucose goes to your liver, where it is converted into glycogen.
Glycogen is stored in the muscles. Once the muscles have enough glycogen, any excess is sent back to the liver again, where it is stored as triglycerides (also known as fat).
The body has an unlimited capacity for storing triglycerides, and some of them will end up in your bloodstream. A high amount of triglycerides makes the blood thicker. Thickened blood is more likely to clot or cause blockages, which can cause a heart attack or a stroke.
