Wait wait, what exactly is your current weight, and your lifestyle living? You gotta give us more info so we can see if this is actually legit.
Also I agreed that one year is too loong. I lost about 10-15 pounds for not even a month, 3 weeks maybe. It just depends on your determination to loose those extra.

current weight 251, lifestyle... Um I eat a lot and I am physically active I run 5 days a week. I don't know what else to tell you but I'm willing to answer anything for the sake of transparency.
