DM,
Don't get discouraged! I've been LCing for over a year now on various plans and there are several factors to keep in mind:
1. Not all plans will work the same for all people (despite all the wow you hear about people losing zillions of pounds on Atkins, for myself and for some others, Atkins did not work). One way I've been doing it is to give a plan some time and taking a few things into account (not just weight loss, but overall carb cravings, energy feelings, and measurements) and if I see it isn't doing me good, I look into other plans. LCing is not a one-size-fits-all type of plan (which is why us lifers call it a Way of Life and not a "diet") so it takes time to find the right one
2. LCing on the whole is a slow weight loss process. This isn't a fad diet where you can lose quickly. But the upside is you don't gain it back like with some fad diets since this is a way of eating.
3. Your body's resistance to dieting. If you're like me (I've been yo-yo dieting since I was 14) I already know my body is very resistant to weight loss (which is why I don't weigh myself on a scale). It takes more time for me to show the lost inches.
I was also getting discouraged going back on GO after a carb blowout few months but after about a month I started seeing the inches go. The thing that made me stick with it was that I noticed my energy level was up and my carb cravings went down significantly (I was even able to pass up biscottis that one of my grad classmates passed around
). That was enough for me to know it was working. I don't weigh myself but I did measure myself a few weeks ago (after about 1 1/2 months on GO) and I lost 2 1/2 inches from my stomach which is no mean feat.
Again, my advice is to be patient and wait it out. As long as you're feeling good on GO (and I'm assuming that you are if you're still on it) then the pounds will show up eventually. Also, keep checking yourself against some clothes that are tight on you. That's a surer way of knowing you've been losing than the scale.
Hope that helps!
Tam
