Sadiga, maybe I'm crazy, but I think you can lose at least 25, I lost 24 lbs in 30 days in April when I changed to a Primal lifestyle
http://www.marksdailyapple.com/ at least its something to look towards, don't put a number on what you want to lose, just work hard and buckle down and do it and see where it leads. You can at least get healthier in 30 days, who knows how much weight loss that will be.
