hi just want to say firstly great site and loads of great advice, hope someone can give me some good advice, right my problem is:

i have been training on and off for about 4 years had some really good progress but have just got back from travelling for a year so before i went i was 14 and a half stone now just weighed my self and tipped the scale at just over 16 and a half, basically when i was away i did not think twice about eating badly and now im gutted as im back home and basically lost what muscle i had and now just look fat, im 5 10 aswell just incase you needed to know, i have just bought myself a exercise bike and am gonna do 40 mins unfuelled exercise everyday to strip off my fat, my dilema is do i start up the weights again or do i get down to my goal weight first. i have always had a problem with my weight as i have found that all my mates can eat loads and look defined but i hardly eat anything and yet i put on fat, so can anyone help me to produce a new diet or eating regime as i wanna get cut and then train properly, i know its gonna take time to loose at least 2 stone but i will do what ever it takes any advice will be truley appreciated so i can start my new life, p.s can i some how speed up my metabolism as i think i have the worldst slowest.

thanks in advance
