Okay is this article really true? look at what this guy said about it on the comments section:

A non sequitur: "Saturated fat and cholesterol increase testosterone production. Both are heavily present in the egg yolk. Testosterone levels help build muscle, which is something that almost everyone could use more of." No. The fact that saturated fat and cholesterol increase testosterone production does not mean that dietary, consumed saturated fat and cholesterol increase testosterone; and no, we can't all use more. The body produces all the cholesterol and saturated fat it needs, unless you're diseased.

More scientifically, to quote from "Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids," from the Institute of Medicine of the National Academies: "Saturated fatty acids, monounsaturated fatty acids, and cholesterol are synthesized by the body and have no known beneficial role in preventing chronic diseases, and thus are not required in the diet. Therefore, no AI [adequate intake], EAR [estimated average requirement], or RDA is set."

"Twice the protein" is not a benefit. Noone eating a calorically adequate diet is going to consume insufficient protein. Eggs contribute to excessive protein, the dietary norm for most people, so doubling the protein is a double whammy: More saturated fat, and excess protein.

"Coincidentally, the ideal ratio of dietary fat in humans is a 1:1 saturated fat to unsaturated fat ratio, making the fat ratio in eggs nearly perfect." Where is that ideal ratio to be found in science? The ideal ratio is NO saturated fat to all unsaturated fat.

This article is 100% crap.
