My weight follows kind of a weekly cycle.
Sunday mornings are my official weigh ins (now that I'm drinking whey, that is true in more than one way ...)
From Sunday through Tuesday, I usually lose the weight I'm going to lose for the week. Some of that loss is water weight loss. Wednesday mornings I'm usually up a little, Thursday and Friday the same, Saturday I make certain I'm fully hydrated (I don't want the Sunday morning weigh in to be affected by dehydration or something) and then I have my Sunday weigh in again.
I've started keeping an exercise log because I'm now walk/running over twenty miles a week as well as weights once and Judo twice. I'm also trying to make myself stretch more, and writing it down seems to help.
I don't know if other people have the same cycle or not, but I thought I'd post mine. The cycle kind of set up after I'd lost the first forty pounds or so.
On weeks where I've hit a plateau (a week where I'm going to lose only a pound or half a pound) the cycle can be distressing if I'm not tracking my calories, which I do. Since I hit plateaus about 1.5 weeks out of four, the routine I use to eat helps me remember I'm not doing anything strange or suddenly eating more.
Keeping track of my weight also helps me not get lost. I'll remember, for example, that I was somewhere in the 190s. But having written the numbers down I'll know that "somewhere" was 196 last week, 194 this week. The same for the 180s I'm in while posting. That was 185, then 183 and 181.5 this morning.
As I've gotten used to the rhythm, and had a little bit of contact with others who have been through the same thing, it has helped me appreciate what is going on and not worry about the fact that this is a biologic event, not a mechanical one.
Thought I'd share this to help anyone else who has started to hit the plateau pattern after being in the Shangri-la method for a while.
