I belong to a fitness forum which is very anti-fat. Someone posted about how eating a high fat meal has the immediate effect of making the blood thicken so it cannot circulate properly.

When I questioned this, the answer was ....read this:

Hardly scientific or unbiased, but...

Now I need to justify my position with articles. Steer me to some good ones, people!

Find Peter Aherns references in Good Calories Bad Calories. This goes back to the 50's. He had the same person on a low carb diet and a high carb diet. He then pulled blood serum after each diet trial. Guess which serum was clear and which was cloudy? Answer: the high carb diet had opaque blood serum.

And carbs are converted to trigylcerides by the liver. And what are triglycerides? Fat.

Hard to argue with idiots IMO.

And Pritikin committed suicide. Could be due to his low cholesterol which drove his depression.

That statement from the first site had me One meal, can increase your risk of heart attacks people, one meal in your whole life? One meal in a day? One meal in a week? They don't say. One could conclude then that a meal you ate when you were 10 sets you up for a lifetime of risk.

The fat (bad cholesterol and triglyceride) is indeed bad for your heart in high levels BUT on LC the fats are used by the body as fuel thus lowering the levels in your blood to a point where they are in fact lower than they would be if you were eating carbs and trying to cut on your fat intake.

Thanks, guys!

High carb, low fat diets are what turn your blood into sludge. If you want a visual, check out http://www.geocities.com/prince_of_orion/

From the menu on the left select “The story in graphs” and go to the bottom of page two - you'll see vials of blood plasma while on different diets. The LC one is the LEAST milky/viscous.

Dr. Pritikin contracted leukemia which was treated for nearly 10 years before he committed suicide.
After his death, it's reported that Julia Childs told his widow something to the effect that if he'd 'had a decent meal every once in a while', he might have lived longer.

I can remember watching "What will they think of next" (it might have still been Science International at that point*) back in the seventies, and they did a bit on a study that concluded "Mashed Potatoes" were the most statistically significant dish eaten prior to heart attack.
