Resolved Question: Green Tea vs. Oolong Tea, Wu-long Tea, Wu-yi Tea what is the difference?

Would I possibly get the same or close to the same results with drinking green tea? Along with diet and exercise of course. But is there something special in the other teas or could the same be done with the green tea?

I was researching the types of slimming teas. Oolong teas and the others have no calories, no sodium, no carbs, no protien - same goes for the green tea.
