I've been on Atkins for about 4-5 weeks. I lost 7 pounds during the first two weeks, and felt very optimistic. During the past 4-5 weeks, I cannot tell a lie...I did have two "carb" days. But...outiside of those two days, I have been EXCEEDINGLY strict with the carbs, keeping them WELL under 20 grams. Much to my extreme dismay, I have not lost any additional weight, although I am in ketosis(my strip indicated that there were moderate to large amounts present). How can your body be burning fat, yet the scale is not changing? The idea here is to lose weight!!! I'm getting close to losing weight. I'm not saying that there hasn't been a change in the way my clothes fit, etc., but I expected to have lost, at least 10-15 pounds at this point. Does anyone have any answers/advise???

Thanks!
