Low Fat vs Low Carb Diet and Familial Chylomicronemia Syndrome (FCS)
Patients with familial chylomicronemia syndrome (FCS) are missing the enzyme (lipoprotein lipase) necessary to remove triglycerides. Since standard lipid lowering agents require that enzyme to be effective, those drugs do not work in patients with FCS. A more effective treatment for these patients is a strict low fat diet.
In this video, Daniel Rader MD, of the Perelman School of Medicine at University of Pennsylvania explains that the diet should be a low fat, and not a low carb diet, to be effective.
FCS is a rare genetic disorder in which children and adults have extremely high triglycerides and chylomicrons.
