Is it essiac? It's supposed to be for cancer, but my not stepdaughter has diabetes and started using it. It's the only thing she's found to keep her blood glucose where it's supposed to be and she's lost 30 pounds I think.
Are you maybe confusing a 'diet tea' with the 'tea diet'?
From what I've heard, you basically cut out all coffee and other hot bevvies, and drink 7-8 cups of black/green/white tea (and by white I mean white leaves, not tea with milk) no milk, no sugar, a day as it is a diuretic (basically)....
Like anything, once you stop doing it, you'll put the weight back on.
I find it hard to put my faith in anything but a sensible diet and moderate exercise.
No, I am not ashamed that I have a major crush on a man who dressed in tights and made faces for most of the 80's, and now plays a crippled drug addicted doctor...and is almost the same age as my father.
