I usually tell patients to fast from bedtime [on the groungs that we are
trying to find their physiological trough levels]. Fasting from 6pm until
9am would give an unnaturally low estimate of the truth. And since
cholesterol is barely affected by fasting whilst triglycerides have a broad
interpretation of what is significantly elevated, it doesn't really matter f
the trigs are 0.4mmol higer after a 12 hour fast than after a 16 hour
fast...
