I'm guessing that they have been banned for health & safety issues? (like ephedra)
You might want to have your primary doc. recommend a Registered Dietician to help get you started on eating right to help with wt. loss, and just invest your $$ in a 3 month gym membership and a trainer? Many times you can find both in the same place and your health insurance might even cover a portion of the cost.... You don't always have to make a long-term contract with a gym, although they don't advertise that fact.
