Levels of fat in your blood move much more slowly compared to blood sugar. Therefore, it is unlikely you will have levels that are too low. However, if levels of fat in the blood remain too high, this leads to a chain of events that triggers 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. Individuals in the latter category should try to eat meals that do not lead to such responses.
