To take things back to the original topic...

I've been low carbing for almost a full year. I quit smoking 6 months ago. My weight loss stopped entirely despite not changing my calorie intake or my exercise output. I've lost a grand total of 7lbs in the last 6 months, compared to 32lbs in the first 6 months.

I had a couple of packs of cigarettes over the last week, and 5 of those 7lbs walked out the door.

I'm not going to say it's good for anyone, or that I recommend it, in fact I quit 'again' this morning.. but that's what my experience with smoking and low carbing has been.
