The 36h Fast
36 hours has been my longest fast to date.
I'm not sure I will push it further - I might. It went fantastically well.
I Gots Energy!
I feel fantastic. I have energy, I'm not tired. I'm not hungry. My mood is great.
Sure there were a few dips during the 36h, and the odd hunger pang - but I have dips every day, and odd hunger pangs.
In fact I would say my hunger was less than between meals on a regular eating day! And way less than when I try to reduce calories. I think that's what makes fasting so appealing (and, frankly, bizarre).
I did something to make it a bit crazier - I ran 15km at the 22h mark of the fast, on just water. Well, technically, lemon juice and water with a bit of salt... to each one's own! No calories, though, which is the main point.
I was slower than I'd have been fully carb'd up carrying a bottle of Gatorade - no question. But I did it, and didn't feel bad. I've done a few fasted runs leading up to this, so I figure it's my body adapting. In studies fat-adapted athletes were able to metabolize 2.5 times as much fat as high carb athletes.
Fat For Fuel
Fat is not as efficient of a fuel - true.
Fat is not already in your muscle like muscle glycogen is - true.
But there's a whoooolllle lot of it. If one turns to ultra-endurance then fat is going to be a big part of how you get to the end. Better learn to burn it for fuel!
I'm down about 8 pounds since September (some I'm sure is water/etc!) as of this morning, 36h fasted. Even unfasted I'm down ~4 pounds, so some of it is definitely real weight loss.
Going to keep on it! Feels like I finally hit on something that works.
