Should I take my Creatine & Endothil with my Hydroxycut?

I gain too much weight in the past 8 months; 45 lbs to be exact. I have been procrastinating to workout after my knee injury. My knee healed seven months ago but I haven't made an attempt to get back to the gym which I know it was stupid of me. Now, I have a family reunion in 4 weeks for christmas, and I have to tell you that my family is big (40+ aunts, uncles, cousins, brothers, sisters, ect) and very close so we tell each other everyone else's buissness and make jokes, but I don't wich to be the theme this year. So I am planning a very strict diet where I will separate my carbs and proteins with a combination of creatine, endothil and hydroxycut. Now I have taken these supplements before but separately. Can anyone give me some advise if I will kill myself doing this? I don't trust a doctor's opinion because, lets face it, they don't know anything about dietary supplements. Due to new laws any company can make dietary supplements and the FDA doesn't have to research them unless it causes death or injury, so doctors are never taught about this products during their training. Can anyone help? Or recommend different supplements that will help me loose 45 lbs in four weeks? NOTE: I was able to lost 30 pounds in one month before so the goal is not a problem but I need to loose it faster now.
