I have only lost 3 pounds in three weeks. Have been sticking to it but not doing much exercise (40 degrees in Spain) though I have been using my Power Plate.
Perhaps it's because it's so hot that you're retaining more fluid?? Don't be disheartened... keep going, think positive, 3lbs off is a whole lot better than 3lbs on. xxx
I've had problems with water retention lately. If you can't think of any definite reasons, perhaps go back to basics and write everything down, we all get a little lax after a while.
