When we eat fats, they are absorbed by our gut and enter our bloodstream as large molecules of fat (chylomicrons). This is a normal healthy process. However, if the level of fats in the blood remains elevated this can trigger inflammation, leading to various problems including narrowing of your arteries. Certain fats such as those from processed meats cause worse responses than healthy fats such as olive oil. In the long term elevated levels of bad fats in your blood can lead to heart disease and metabolic diseases.

Individual ability to process blood fats vary immensely - some people can eat large amounts of fat and have almost no rise, while others may still have very dramatic rises many hours after the meal.
