In this video, Mark Sisson covers what he eats on a given day. He starts the day with a cup of coffee and a crossword puzzle, mostly for the ritual of it. Due to Metabolic Flexibility, he doesn't need to eat anything right when he wakes up. He can even go past breakfast and wait until 12:30 or 1:00 to eat.
For lunch, he goes with a salad with greens, salmon, and a good, healthy dressing for flavor and healthy fats. This meal fuels him up for the rest of the day until dinner time, which he usually will eat around 7:00 or 8:00 at night.
Without any need to snack throughout the day, he doesn't eat until dinner time. He'll eat a ribeye steak and some veggies like asparagus. He'll also have a glass of low-alcohol, low-tannins, no-sugar wine (or two) with his dinner. Watch the video to see more!
