In all honesty, I don’t know how many lipids are in the whole human body. That would be very difficult task to find out.
But when we see patients, we measure their cholesterol and tryglyceride levels (two types of lipids) to give us an idea of how many overall lipids there are in a persons body.
In a healthy person, the blood cholesterol level should be below 200 mg/dL measured in a sample taken from the patient. The triglyceride level should be below 150 mg/dL. If the levels are higher than this, then we expect the overall levels of lipids within that person’s body to be high and we can prescribe lifestyle changes and medical treatment to try bring the level of lipids down.
So although I did not answer your question directly, I hope it gives you come knowledge on what you were asking.
