MYTH #1 – Eating fat will raise LDL levels. BUSTED - As was described above, dietary fat (yes even the saturated kind) is shuttled via chylomicrons from your intestines to the rest of the body. This does nothing to the LDL level in your blood. The amount of dietary fat that reaches the liver also has little to do with the level of total cholesterol production. We know that in general if you eat less fat, your liver makes more cholesterol, you eat more fat, and your liver makes less due to the fact that there are more chylomicrons circulating. Your body is extremely efficient at regulating itself.
And one of the best quotes of all time for your consumption came from the famed Framingham study. “In Framingham, Massachusetts, the more saturated fat one ate, the more cholesterol one ate, the lower the people’s serum cholesterol “(he meant LDL). Dr. William Castelli, Director of the Framingham study, 1992.
So take a step back, where does the LDL come from? It originally comes from the VLDL once it has some fat removed from it. Now remember that VLDL’s job was to transport oily substances which were already in the body, not the dietary fat we have eaten (chylomicrons job). So what raises VLDL? Not dietary fat. Think excess carbohydrates. Excess carbohydrate turns into triglyceride very efficiently in the liver, and since it is already IN the body it is the responsibility of VLDL and ultimately LDL to transport it through the body. It is actually proven that generally a lower carb and higher fat diet LOWERS VLDL level. So eating fat will lower VLDL, and in turn the harmful types of LDL. Oh, there are different types of LDL? Absolutely. We will get to the different types of LDL in just a minute.
We didn’t think of this on our own I am sad to say, the American Journal of Medicine did (1) as they were trying to prove the Atkins diet was bad for you. Oops.
Also, in November 2002 studies were published espousing lower carbohydrates for improvement in cholesterol levels. In one study Duke researchers found that “after six months, participants on the Atkins diet had lost 31 pounds, had an 11 percent increase in HDL (good cholesterol) and a 49 percent drop in their tryglyceride levels. Atkins dieters had a 49% reduction in VLDL levels, versus 17% for those on the low-fat group”.

MKB I know but I work full time and don't have much time to eat every 2.5 hrs so I bring 2 of my egg shakes and 1 solid meal for my break. Other wise I couldn't pull it off I figured to just take the chance. Oh and I add 1 cup quick oats too
