This came up on another board: an Atkins dieter went on a mixed diet for a couple of days and reports she continued to lose weight at a rate of 1/2 lb. a day. No water weight gain. What could explain that? An underlying problem like undiagnosed diabetes?

How about undereating on LC? It's pretty common. Adding back in carbs is also adding in calories - and carbs are thermoginic, they're going to raise body temp as well (I know my shoots up big time when I do a refeed).

FWIW, I've done refeeds and not gained anything for a few days, then gone up a few for a day and right back down the next.
