So the eggs were cooked in a small amount of organic butter or butter on top of the eggs? No salt or pepper?
The egg is nearly impossible to digest, this forces many human cells to BURN UP in the process, as these cells BURN UP we feel the energy, a FAKE energy that did not come from the egg, but from our own vitality. To give an egg to a child is to poison him for 10 days according to what I have read.
As a child I raised chickens with my mom and we sold 100 dozen a week on average, we lived on eggs and chicken, I was raised to believe this was great food! My mom still eats chicken more than any other meat, still loves eggs.
You could also be lacking an essential mineral or nutrient that is present in the egg and those are better when they come direct from the plant, because the egg is second hand always.
Take a tablespoon of Lecithin and I bet your gravings go away, the egg has allot of lecithin.
