Hi Kathy,
Glad to see your happy with your results and your feeling good, thats the most important thing.
Are you truly counting carbs, like using fitday or something like that. If your going over (especially by things we are not even aware of like splenda or coffee, cream, cheeses, etc) the weight loss will come off slower.
For me it took several weeks before I REALLY got the 20 grams of carbs down well, meaning knowing exactly what I was eating. Are you measuring things? Also.... I was one who has to watch my calories as well while following atkins. If I ate over 1600 I would not lose weight. So I learned by keeping my carbs at a true 20 grams and eating 1500 or less, the weight came off fast !!!
You said you don't exercise.... well here's another thing that could have happened. You might have lost weight but added some muscle by all the walking?? could happen.
Bottom line..... give it some more time
AND DRINK LOTS OF WATER !!!!
Good luck.
