Feezles the jiggly fat thing is the theory behind "whooshes": basically, when you're dieting, your fat cells deplete of fat as they burn it for energy, but as one of the many millions of clever ways our body has to hang onto fat, it fills the fat cells with water so they'll be easier to re-fill again when we catch our next antelope. The upshot is that people notice, basically, that their fat goes "jiggly" - having been firm and packed, it goes a bit marbled looking. Then at some point your body gets to a certain hydration %, it presses the "drain" button, eh voila - a whoosh. It was something they noticed in the Minnesota Starvation experiment, especially the several-trips-to-the-loo thing.
On a Fast Day I normally have a couple of cups of tea, a kale, carrot and apple smoothie, a couple of hard boiled eggs, and then in the evening I have something quick and dirty like a tray of roast chicken from the supermarket with a bit of mayonnaise, or a tub of soup. I started doing that because it made it easier to have the calories printed on the side, but I carried on because I find it much easier not to cook on a fast day!
I actually wasn't counting very closely before Christmas because I was maintaining pretty well, so I wasn't keeping an eye on nibbling, and with the mayo etc. I was probably coming in at more like 700. Now I'm dying to kick the Christmas gain, I'm going "Mega Fast": so today I've had a boiled egg, 2 Babybels, a couple of spoonfuls of Cottage Cheese and a Miso Soup, and 3 cups of tea. Surprising how little you can eat when you put your mind to it. I'll probably relax a bit again when I've got these last couple of Lindas off though.
I've been chugging water too Kiki and Feezles so with a bit of luck I'll see you at 3am for our fifth wee
