can't do it for myself but i have to for my wife and kids

Hey everybody, I'm Vince, I've been married for 9 years and have 2 boys. My wife and kids are the main reason i am here. I owe it to them to take better care of myself. I am a Correctional Officer at my county Jail, for 5 years. In that 5 years i have gone from 38" waist and XL shirts to 46" and 3XL.
Before i got married i weighed 170 now i'm 275, way too close to 300 for my comfort. if i could get down to 200 i would be content. my real goal is that 170 mark.
