Thing I notice is that you're not really sticking to the plan. You're doing your own version of it. For starters you're limiting your carbs by all the weighing. That is not part of slimming world. Secondly you say you're doing EE, but your typical menu resembled a green day. So it was as though you were doing a green day, but weighing out your carbs as you would on a red day. But on either of those days you're supposed to have 2 HEB and 1-2HEA. So I would say from your menu that you are not eating enough, or eating enough of the right foods. SW after all isn't a calorie controlled diet, but rather the proportions of different nutrients that make it work, i.e. the high fibre content promotes weight loss.
I know it's weird to get your head around, but I seriously always lose more weight if I have all 15 syns and 2 HEA and 2 HEB (I'm veggie, so stick to green days.) I would say try to do 100% EE, eating both your free meats and carbs WITHOUT WEIGHING until you're satisfied and use your syns and appropriate HE's.
Have to agree. I do EE but don't weigh or measure anything except HEA, HEB and syns. I kept staying the same when I wasn't having enough syns. Once I started having the 15 syns a day the weight starting coming off every week.
