Overnight weight gain HELP!

You cannot gain 1.5 real pounds overnight.

How many calories did you eat yesterday? Was it 5,250 calories more than you burned? If not, you didn't gain 1.5 real pounds. If so, that weight would NOT show up so soon.

The likely cause: water retention and/or extra food weight.

Between yesterday morning and today did you consume anything that could have added 5,250 calories to your day? Think hard...do you recall eating half a cheesecake perhaps? Or 52 of those 100-calorie packs?

This is a normal fluctuation! Don't worry about it!

That's nothing, I gained 3.2 pounds overnight on Saturday; damn Chinese food.  It all came back off within 2 days, just drink a lot of water and don't freak out.

Sodium is a big culprit. Sometimes if you weigh in the morning you are more dehydrated after sleep than a weigh in later in the day. Sp varying weigh in times could be a part of it too.

@oxford007 I was wondering where the other half of my cheesecake went! :)
