White tea contains anti-obesity substances

BioMed Central's Nutrition and Metabolism journal published the results of a study at Beiersdorf AG that found that an extract of white tea inhibits the growth of new fat cells and and breaks down the fat in existing fat cells.

After treating lab-cultured human pre-adipocytes with the tea extract, the authors found that fat incorporation during the genesis of new adipocytes was reduced. According to Winnefeld, "The extract solution induced a decrease in the expression of genes associated with the growth of new fat cells, while also prompting existing adipocytes to break down the fat they contain."
White tea -- the solution to the obesity epidemic?

I wonder if anyone has tested whether
The active ingredient(s) remain effective in the gut; ie do they survive digestion?
the amount needed to be consumed to be effective would be prohibitive.
