Not wishing to be argumentative here, but the low fat diet is already dying it's death as the saviour to heart disease. Since Ancel Keys, in the 1950's, promoted the hypothesis that high saturated fat led to high cholesterol which led to heart disease peope have been encouraged to eat low fat high complex carbs. This really came in a big way in the 1970s and since then there has been a steady diabetes and obesity epidemic, which leads to atherosclerosis, as the years have passed - no one can deny that. It's now being shown that it's actually carbs, complex or refined, that can lead to inflammation which leads to atherosclerosis. There may also be other causes of atherosclerosis which have nothing to do with diet at all. I won't put in any links, I'll let anyone who wants to find out do searches becasue the thing is for some reason this subject has all get very emotive, even amoungst the medical profession ! So everyone should do their own research.
I have a Home Doctor book that I got from my parents house written in 1955 which was before the dietary advice changed to low fat high carb. It is rather instructive in the light of the diabetes and obesity epidemic we have now. I quote some of the dietary advice:
"Foods for Calories: The carbohydrates (sugar and starch) are the foods that supply most calories and little else; they are the least important foods. But as they are the cheapest and easiest to get they play too large a part in most family diets. They come from the sweet shop, the baker and the grocer. It is fatally easy to fill up on them and leave no room for the other far more important foods........"
"Food for Building and Repair: Proteins is the name given to the foods which provide the materials essential for growth and for the continual repair of the bones and body tissues. They are the most important of all foods....."
"Calories Plus Vitamins: Fats are fuel foods, but in each ounce they provide twice as many caloires as do proteins and carbohydrates. Also most of the animal fats and the vegetable oils contain two important vitamins, A and D. If you eat fat you can obtain plenty of energy from a diet that is not too bulky...."
I do have an extreme diet by many peoples' standards as I eat a high fat, moderate protein, very low carb diet which is sometimes called Paleo, hence my username. It's fantastic and I've never eaten so well, although it is expensive eating meat and fish every day (and nuts and eggs) with lots of veggies without any bread or grain foods or starchy veg or sugars.
