These guys are barking up the wrong tree. INSULIN is the fat-making and fat-storing hormone. FATS do not stimulate insulin, CARBOHYDRATES do. Natural fats (like butter, cream, steak fat, egg yolks, coconut oil) are essential nutrients, especially for such functions as forming hormones and neurotransmitters, and the proper formation of hair, skin, and nails. UNsaturated fatty acids (margarine, vegetable oils, etc.) on the other hand, can cause blood clotting and "age spots," and are so detrimental to health that they are even used to suppress the immune response after transplant surgery.
This is the kind of silly tail-chasing we get when we let the vegetable oil and sugar manufacturers decide what we should eat, and influence government (which has NO business telling us what we can eat in the first place) to make laws mandating that we eat more of their trashy synthetic foods and less of the historically nutritious and nourishing natural diet our grandparents were raised on.
Cholesterol, for instance is such an essential nutrient for cell integrity that if we don't eat ENOUGH of it in our diet, our body will make it. From SUGAR.
Those triglycerides swimming around in your blood? They probably came from that 1-pound cinnamon roll you washed down with orange juice this morning, and chased with that big cup of Starbuck's double-shot high-test espresso (low fat cream and lots of sugar, of course...), and they are on their way to your fat cells, thanks to the action of the insulin you stimulated.
Go HERE and do a little research into the FACTS. Dr. Enig is a lipid chemist. She KNOWS her fats.
