General LC
Links to sites that may be of interest to low carbers: some LC specific, and some not. While we aim to provide the best in carb-friendly resources, content changes rapidly online, and sometimes, we just miss something. Hard to imagine, we're sure, but it's been known to happen. We encourage you to always critically evaluate information you review as you're making important choices about your lifestyle and health. 
Nutrition & Metabolism Society
Dedicated to minimizing problems of obesity, diabetes & cardiovascular disease, the Nutrition and Metabolism Society believes that the therapeutic potential of low-carbohydrate diets is under-investigated and under-utilized. We at LCE agree! Their mission is to have the governing agencies eliminate the current dietary guidelines, acknowledge the scientific research supporting health through proper nutrition and fund further research in this area.
Wellmix 360
Wellsphere is a social networking site for fitness and health. While not all of the site focuses on Low Carb, this section does, and LCE is one of their featured LC sites!
