Welcome to SparkPeople and to the Slowest Loser Team! I have had what I consider great success with SP, because I have lost 42 pounds since I started. I started August 2011, so that sounds like it's taken me forever to lose the weight, but as you talk to other Sparkers on this site you will see it's all about taking baby steps, making small changes gradually, so that it isn't all overwhelming and discouraging. You learn that if you mess up for a day or two, you don't give up, you get back up and start again! And having friends, being on teams and espcially (in my opinion) tracking your nutrition and exercise like it's your job, makes you accountable. Keeps you honest!
This site is amazing and has so much information, workout videos, and just plain encouragement and inspiration. Take time to just click around on it and see what all there is in the way of help! Speaking of help, if I can help in any way, just visit my site, and leave a comment or question. I'm retired and my mother lives with us, so this is a lifeline for me and I'm on the site a lot! Come see me! Good luck! And remember -- baby steps!
