Welcome. Think of it as a lifestyle instead of a diet and this might be the last change you have to make. I lost 90 pounds in 8.5 months last year by cutting back on carbs, staying under 1700 calories and doing about 5 cardio or strength training classes a week at the gym. Good luck!
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
