I have been taking Healthy Weight Gold for a month and it has helped me. It is not a quick fix or diet pill really, but it helps with appitite suppression and energy. The main ingrediant is Svtol which is green coffee extract. It doesn't make you gittery though because it has less caffiene than a cup of coffee.
Now note, that I am not losing weight fast with this (healthy 1-2 lbs a week) but it does help with my mood and energy. I used to hit highs and lows in being tired during the day and now it is more even. And because of that I have been more active and working out at least 30 minutes 5 times a week.
The only side effect I noticed was a bit of dizziness if I did not drink at least 8 oz of water with the pills within 30 minutes.
It may not work for everyone, but I am having success.
