Hi! Oh, so many great questions, but they bring even more questions to mind! LOL
You've been LCing for about three weeks, have lost 7-8 pounds. Well, that's pretty darned good, actually! Did you lose anything during the third week? If not, don't worry--that's very common! Most of us have gone through that third week with very little or no weight loss. It seems the body likes to gives itself a bit of adjustment.
Have you taken your measurements? I lost 7 pounds on Induction but by the end of the third week needed a size smaller pants. At times, our weight loss fairly stops but usually the body keeps losing a little bit (either no weight loss or inches lost for 4-6 weeks or longer is a real stall).
I am wondering if you're using any of the frankenfoods, like low-carb bars, shakes, candies, breads and stuff like that. Any food that has sugar alcohol shouldn't be used on Induction, and only very rarely afterward. The problem with sugar alcohols (except for Splenda which doesn't seem to have any sugar alcohol carbs) is that while the body metabolizes them slowly, most of the carbs from them are indeed metabolized. If your body doesn't metabolize them then they cause all kinds of intestinal upsets (so why bother eating them?). As for grain foods (like LC breads, tortilla shells, etc.) those really should be saved for the later phases of OWL--and shoot, I have no clue if you've been eating them or not! LOL Anyway, see what I mean about your questions just giving me more questions?
I'll quit rambling now--seems I'm really good at that today--and will say
WELCOME!!
