Need help losing more weight ###

Hi guys, can anyon egive me some hints for a jump start. I had WLS surgey in 2004 I weighted 283 at my highest, I have maintained 173 for 5 years. I started noticing a pound or two here and there, I am now at 180 and very frustrated. I eat well and work out 5 times a week doing cardio. Does anyone have any suggestions?

Thanks
