Hi. What a dilemma! This is what I am worried about too if i ever get to moving up the plans! If it helps at all I always put on exactly 5lb when I come off the diet (on holiday etc) and reintroduce carbs. This always goes away again as soon as I get back into ketosis. However, in your case you really dont want to do that do you as you are moving towards mauntenance. KDs advice seems best, but I would add, get out your best jeans, keep trying these on and as long as you are happy with the fit, stay off the scales for a few weeks. Good luck, keep us posted
