What does the world's richest person have for breakfast?

Elon Musk mentioned on a show that he eats a steak, four fried eggs, and drinks lemon water in the morning.
That's it, no carbs, no vegetables, just enough protein and enough water, and his condition becomes extremely good, with energy being very vigorous, always in a fully charged state.
This is the secret to the billionaire maintaining super strong energy.
