newbie here, need friends!

I need some friends please! In need of some major support! Also looking for friends with an open diary. I need some nutrition advice. Im 200 lbs 5'1 I don't look 200 lbs ( thank goodness) but I still have a bigger waist. I would like to get down to 150 eventually. For a shorter term goal I would like to get down to 170. Any and all help is appreciated! Also, some exercising advice would be really helpful. I normally do the elliptical at the gym and then some weight training (abs, legs, arms) I do the same thing at the gym every time, what should I really be doing? Thanks guys! and good luck on your weight loss journeys.
