I believe that crappy carbs like the buns is what would elevate LDL and triglycerides. But I also think that pounding down 400+g of carbs ,even from something good like yams, would do the same.
If you think that the beef they use is of the highest quality, think again.
I would also recommend reading Fast Food Nation (also about to become a film I believe).
The lipid profile of the muscle cell reflects the diet, and if you eat too much saturated fat and modified trans fats (and Mackie D's food is highly processed), this affects the membranes.
They become stiff and blocked. This is especially true when the combination of simple carbs (the bun and all the sugar in their sauces) is combined with saturated fats.
This leads to insulin resistance, so the great anabolic effects of insulin are hampered as the insulin receptors no longer function as well to trigger glucose and amino acid transporters to the surface of the cell.
A calorie is not a calorie is not a calorie and not all fats and carbs are created equally.
You are what you eat - junk in, junk out.
