OMG Welcome to my world! I've not lost anything (in fact I think I've gained a bit) since March 23rd. I've been exercising like a fiend (weightlifting 3 times a week, yoga once a week, spinning on average 3-4 times a week, keeping my proteins above 50, my calories below 1400, elliptical 2 times a week) and nothing is showing up (or falling off).
HAVING SAID THAT - I have to admit my body is doing something odd - my tight clothes are looser and my body is more flexible than ever (how many 45 year old women do you know that can put their nose on their knees?)
Please, just stay doing whatever you are doing, if you've lost weight doing that before. And little by little start changing your mind set - the weight lost will stop at some point. So then you have to focus on something else (ie the way your clothes fit).
You'll do it - you are doing great so far!
