What's the worst diet you've ever heard of?

I've known this guy for a few years, and I've always suspected that his diet was complete shite. I finally asked him about it, and here's what he eats:

He makes a loaf of bread every morning on Monday-Thursday. in his bread, he puts sunflower seeds, almonds, and spinach. The loaf finishes baking around 4pm when he gets home from work. He is also an alcoholic - not admitting it though - and drinks at least 6 beers every day of the week along with scotch on the weekends. That's ALL he eats on Monday-Thursday. Bread and beer.

On Friday, he waits for dinner to eat anything, and he eats a steak with his girlfriend, some kind of vegetable that she cooks, and a salad. He says he'll eat a "few steaks" on Friday nights.

On Saturday, he does the bread thing again, but he says he's usually hungover from Friday night and won't eat much until Saturday evening when he goes out drinking again. He said he eats a lot of nuts before he starts drinking because they "help with the whoozyness."

On Sunday, he and his girlfriend smoke a whole chicken to make tacos with fresh pico. He'll also eat some kind of breakfast food at a local diner on Sunday mornings.

He's a bit of an odd guy. Very, very regimented. Takes one vacation a year to the same condo on the same beach. Works a lot. Has his whole week structured - Wednesday is Netflix night kind of thing.

Sometimes I think he has some form of high functioning autism, and I definitely think so after hearing about his strange eating habits.
