CCLL in Greater Detail:

Your CCLL is your own very personal carbohydrate threshold. It’s the number of Net Carbs you can eat each day and still lose weight.

Your CCLL is influenced by age, gender, physical activity, hormonal issues, medication and other factors – all of which can raise or lower your metabolic resistance (how resistant your body is to burning fat). For your reference, here’s a chart representing metabolic resistance and the resulting CCLL range:
