I cut calories to about 1500 and exercised (mostly just cardio at first, now cardio and strength) and lost 90 pounds in 37 weeks (just about 8 1/2 months) in 2011. It took determination and strong will to stay on plan just about every single day. I had 2 mini vacations (camping with girlfriends) and 2 family weddings plus a week long family - friend camping vacation during the time I was losing. It can be done. I tried for 1% of my weight per week as my goal. If you do the same, you will go from 229 to about 178 in 26 weeks (July 1st.)
Welcome to the board. Good luck - you can do this.
Life style change started on Jan 13, 2011. I was going to lose 100 pounds by Christmas.
I lost 93 pounds by Oct 1, 2011 and am holding there for now. We'll see what happens.
New goal: To maintain at about 160
Final Goal: To decide if I need to lose more
Just Keep On Keepin' On
