Beth...from what I've read, even those who are very petite (or vertically challenged as I like to call myself ) should not go below 1,200 calories daily; otherwise the metabolism starts lowering to compensate for the famine that it perceives is going on.

Janet...I know that you said that you're not hungry, but you need to make an effort to get those calories up at least above 1,200 consistantly. I didn't catch how low your calorie level was the first time I read your post. The gain might just be TOM water retention, but your body could also be putting on the brakes and holding on for dear life because you're not eating enough to sustain it. The best way to add more calories without adding a lot of food is to add more fat in the form of butter, olive oil, mayonnaise or even heavy cream and cream cheese. Smaller more frequent meals can help you keep your calories up without leaving you feeling stuffed too.
