Most fitness "gurus' outside of bodybuilding and the LC WOE will bash Atkins or any other LC plan.

Ask them to produce proof of how/why it is bad for you, and they can't. It's all "my doctor said so" or "my trainer said it." No science backs it up.

Call them un-enlightened I suppose.

As Agony noted though, you may need to take is SOME carbs if you are training intensely with weights. There are LC plans that take this into account, so check out all of the plans and see which one works for you.
