Jesus, nice work, misscloey! You go! Man, I love hearing this. You've made me very happy. Sometimes it's frustrating being the lone voice. On the low-carb forums, it's like preaching to the choir, but when you go outside those venues to the "mainstream" sites, like these, it's very gratifying to see people following it and having success.
I am THRILLED - THRILLED - for you!
Check further down in this forum, there is a poster named Deneciee who has also lost 10 pounds in a couple of weeks on low-carb.
I'm so proud of you, misscloey. You took action and are having success. That's wonderful. I think the half-marathon is a great place to start. The training alone will get you in amazing shape. You can always walk parts of the race. No shame in that. There will be many others at your level there. You might make some new friends.
(raises glass) Congratulations! Don't go away, now. Stay and post your progress!
