Me minus dairy minus meat = NADA

Three weeks ago I gave up meat and dairy products. Well, for the most part I gave them up. And I have been feeling pretty good (except for this past weekend when I ate horribly good food). What do I get for all my sacrifice? Nada. Nil. Zip. Zilch. The scale has not budged ONE LITTLE POUND. To say I'm frustrated is an understatement. Completely depressed would be more appropriate.
