your weight loss may take longer to show up than it has in other people - you shouldn't compare yourself to anyone else. I hope this is a life change and not a way to loose a quick 20 pounds.....
are you drinking water (64 ounces of pure water daily - nothing added)? Are you eating foods from the acceptable food list - nothing else? Are you getting enough fats in daily? Are you eating the bars and drinking shakes? They aren't allowed on induction because of their ingredients.
