From walking five miles from his home to the office, no food all weekend, to using saunas and ice baths in the evening…

Dorsey only eats dinner. Sometime between 6:30 p.m. and 9 p.m. he has a meal of fish, chicken, or steak with a salad, spinach, asparagus or Brussels sprouts. He has mixed berries or some dark chocolate for dessert and also sometimes drinks red wine.

“I’ll go from Friday ‘til Sunday. I won’t have dinner on Friday. I won’t have dinner or any meal on Saturday. And the first time I’ll eat will be Sunday evening. I’ve done that three times now where I do [an] extended fast where I’m just drinking water,” Dorsey says.
