In 1961, a group of investigators from the Rockefeller Institute, led by Pete Ahrens published a paper entitled “Carbohydrate-induced and fat-induced lipemia”.
The authors pointed out that fat-induced increase in TG following a meal is a postprandial phenomenon (we all have high TG for a few hours following a fatty meal) caused by chylomicrons is different from the carbohydrate-induced rise in TG (later found to be caused by elevation of VLDL).
These findings have been confirmed in several more recent studies. Despite this, low fat, high carbohydrate diets are still being recommended as a primary option to reduce the risk of heart disease.
Although low-fat diets may help lowering LDL-C, low carbohydrate diets are more effective in improving the TG/HDL-C ratio.
