There are all kinds of myths and theories about eggs, and proper nutrition in general. Most of the hype is from the bodybuilding world and is profit motivated.
Eat your eggs with the yolk, within your eating window. Moderation and portion control are among the most important factors in healthy eating.
Eating fresh foods, minimal refined carbohydrates (anything with refined cereal grains and/or refined sugars (from any source)) are others. Avoiding trans-fats (partially hydrogenated oils) is the best thing you can do to avoid unhealthy cholesteral levels IMHO
