Weight Loss Program

I am doing some weight training for the first time. I love working out and want the best possible results. I’m seeking to become a personal trainer, do some excersise videos, and be in a few fitness magazines. Do weight loss supplements, such as hydroxycut or slimquik, really work? Are they dangerous for your body? How do they work?
Thank you kindly for answering. I appreciate you all.

I would like to know specifically what supplements to help aid weight loss for Bipolar people on weight gaining Bipolar medication (which slows the metabolism and increases appetitite)
I already know of Green Tea to speed up metabolism and suppress appetite and Acai Berry DOES help you look a bit thinner in the face and relieves minimal bloat if taken moderately.
What other supplements are safe?
I want as much help as i can get!
Thanks!
