Jack Dorsey

Jack Dorsey, a 44-year-old billionaire with a net worth of US$14.7 billion, is perhaps not the most vinous CEO that comes to mind. But he has been advocating a wine inclusive diet for years.
Serving as the CEO of Twitter and Square, he wants to be performant and clear, and he believed keeping strict diets to maximize his capacity. His diet in each week can go as extreme as going through five days with only one meal, and two days without any food.
He has been promoting veganism, paleo diet and the habit of drinking only red wine and lemon juice.
He revealed in a fitness podcast in 2019 that his five weekly meals consist of “fish, chicken, or steak with a salad, spinach, asparagus or Brussels sprouts…and also [some] red wine.”
