it might be a good idea to start a journal and post what you've been eating.. did you also gain weight, or is your weight the same , u just didn't lose anything? I am sure u are doing something 'wrong' rather than saying you're one of those rare people where LCing doesn't work for.. I believe Atkins said EVERYONE will lose in induction even very resistant people will lose something, even though it may not be alot.

However it's possible you might need to restrict calories as well as carbs for those who aren't losing...Perhaps you're on medication etc etc...

At any rate, a journal may be a good place to start, there are some very knowledgeable, very experienced LCers here.
