I am going to offer another perspective. I would expect you (Megan) to be losing about .4 pounds of fat per day, based upon your weight (about 145/150) and your level of activity [.5 to 1 mile of walking each day, plus the occasional sprint to catch a bus :p]. For the most part, any weight beyond that will be water, intestinal contents, glycogen stores and other temporaries, all of which will be returning.
A couple of exceptions:
1) If you had a high level of sodium heading into the fast and maintain a normal level of sodium upon refeeding, then some of the water weight you lose in the fast will stay away... so you could lose some additional "permanant" weight that way.
Borrowed from a couple of posts i made a couple months ago:
[A pertinent exerp about sodium and it's relationship to water in our bodies out of the Wikipedia arcicle.
"Thus, when a powerful diuretic drug is given which causes the kidneys to excrete sodium, the effect is accompanied by an excretion of body water [water loss accompanies sodium loss]."
Since we excrete sodium in a fast, it follows that we excrete body water as well.
Sodium loss is why we lose so much "extra" weight in a fast and the return of this sodium is why we gain so much of that weight back within a couple weeks.
As well, excess sodium causes us to retain excess water. A person with excess sodium in their system who fasts that away and in turn loses their excess water weight (in extreme cases there could be a ton of this) can keep the excess off by maintaining normal, healthy sodium levels. This in turn will lower blood pressure, but that's another story for another day.
But most of us in a fast will dip below our normal sodium levels, drop a good amount of water weight from this and get the water back when our sodium returns to normal.
Nobody here really believes we are burning 20 pounds of fat on a 7 day water fast, right?]
2) If a person had a clogged colon with a lot of impacted feces hardened to the colon walls, a fast could do some great work in that area causing it to losen up and be eliminated. As such, it is possible for a person to lose additional "permanant" weight in this way.
As to the % that will come back, it will depend upon how many days you go. Most of the temporary water loss occurs in the first 7 days or so. So with a 7 day fast i would expect perhaps 70% of the weight loss to return. If this fast was to go 30 days, that % would likely work its way down to about 30 or 40.
