What I'm wondering is why would one want to do an extended fast in the 
first place. I do a 13 or 14 hour fast every day (from dinner, through 
sleep, and until breakfast), and I think that works great. But 
seriously, I can see the benefit of a day or two fast once in a while, 
or just having one meal a day, occasionally. But in an extended fast, 
doesn't your body try to hold on to fat stores as long as it can, and 
start wasting lean mass for glucose generation? Wasting lean mass is 
the last thing most of us need, especially as we get older. I suspect 
that the lure of extended fasting comes from a quest for some mythical 
ideal of purification. It seems related to the myth of colon 
cleansing, which is utter nonsense. I've seen with my own eyes what 
nonsense that one is. Body cleansing and waste removal is an ongoing 
process, non-stop, fasting or not.

Low-carb diet helps keep your cells clean in several ways. One way is 
reducing glycation and AGE creation. Another way is what's called 
"chaperone mediated autophagy" while in ketosis. Check out Eades's
