I was having the same problem. I lost 10 lbs during induction and then started to introduce some of the low-carb items (Atkins Indulgence Bars, protein bars, sugar-free candy, low-carb tortillas) and I stalled. And then to make it WORSE, I gained two pounds back. But, I stopped eating those things yesterday and I lost a pound this morning so I definitely think those are the cause...which is a bummer because they are SOOOO good!
