eating cholesterol doesn’t cause your blood cholesterol to go up. your cholesterol levels are based on your body’s need for the substance. if you don’t eat enough, it will make it in the liver. if you eat enough, it will go to the blood where it’s sent to the locations needed to heal the body (it’s job is healing) and to build new things such as cell membranes and skin.
some people truly do have extremely high cholesterol levels, but that condition is rare.
also the myth that cholesterol causes heart disease has been debunked. please read up before you are nervous about eating cholesterol.
eating 12 eggs a day is perfectly fine, if you are getting enough variety the rest of the day. yolks and all.
the only thing that could happen is, with such a large quantity of the same protein, you body could develop a sensitivity to it. i would cycle the eggs with something else for some time if you plan to do that for the long term. also, eggs are a rather low purine protien, so they won’t give everyone the same lasting energy. you must see how you do on them. some poeple do better with steak or red meats etc.
