I tried to find some guidelines on leangains.com for you but all I could find was:

"On workout days, break the fast with meat, veggies and a fruit. If you’re planning to train shortly after this meal, add a few carbs in the form of a starch source." http://www.leangains.com/2008/06/sure-fire-fat-loss.html

So it probably doesn't matter, though I would think going higher on protein may feel better for the stomach then higher sugar or fats.

I'd go for yogurt and berries and go for a long walk. Then have some bacon and eggs mid-walk. That's if it were a perfect Sunday morning.

The macronutrients are the same no matter how you mix them up. Whatever your appetite says to do.

I'm on ADF (alternate day fasting) right now so I go about 40 hours of water-fast. I usually break mine with coffee that has cream and honey added.

I agree with thhq and Wayne that at the 20-hour point you can pretty much do what you want. It's what you're hungry for and what goes down best. In my case, once I have adulterated coffee to sip I'm not really hungry for solid food so I usually don't eat a meal until the 44-48 hour mark. But then I eat meals arranged exactly the same as when I was eating every day.

I always break fasts with a zero carb meal, but that's mostly to take further advantage of ketosis.
