If you’re referring to a social-media/news-style headline, “Doctors reveal that eating eggs in the morning causes…”, the missing ending matters. There isn’t good evidence that eating eggs in the morning inherently causes a specific disease or health problem in healthy people.
Eggs can be part of a nutritious breakfast and provide protein, vitamins and minerals. The health effects depend more on overall diet, portion size, cooking method, and individual medical conditions than on simply eating eggs in the morning.
If you paste the full headline or article, I can check what the claim actually says and whether the medical evidence supports it.
