What’s the best?

Which one is the best, taking fat burning supplement or taking diet tea? This is the question my friend asked me yesterday after our church service. I told her I have no experience in either of the two because even if I really wanted to loose weight for a very long time already I have no guts to try any kind of slimming pills or slimming tea. I’m afraid of the side effects it may cause me. There are some testimonies about the effectiveness of diet pills or diet tea so I just told her to investigate more and read further studies. It is best if she will consult first a doctor before taking any weight loss product.
