I had a feeling you'd be back to 65 kg in no time! Sounds like the alternate day fasting thing is working for you right now, and I'm not surprised. I actually did that for quite a while and really liked it and felt good while doing it. My digestive tract responded well to it and my energy levels were great, even though that was during the time when my thyroid had tanked and was at one of the lowest points. I've thought about doing it again eventually and coordinating it with work days and sleep days. There are lots of ways to tweak things, too. Some people lower their up day calories and raise their down day totals if they start feeling a little snacky or binge-y. It's really a great way of eating and has lots of benefits, especially when the diet consists of primal food!
I'm glad you're planning on eating what you want on Easter, including the cake that sounds like chocolate HEAVEN! You're going to be where you are hoping to in September, I can feel it!
As far as daily weighing goes, I did find a couple of journals containing weight loss charts and they are good examples of how those little upward bobbles are bound to happen and mean NOTHING in the long run - in fact, they seem to be common right before a nice little drop in weight. Look up paleo charlie's journal and click on the little paper clip off to the side of the title. You'll see his weight loss charts/graphs. It's a great illustration of how true losses are not linear. It's also a good reminder for me not to change things up according to what's going on with the scale and to stick with the slow and steady route!
How's little Joey?
