Sparkles, so happy for you that you're at target, well done!!! I remember your posts from early on and now you're at goal, big congrats for all you have achieved hun. Yes, as Lelly says a small gain can be part of the steps, but this should even out within the first week so don't panic. You cannot gain fat while eating 1000 cals, just not possible! I think totm may be a big part of it...
Are you going to start a maintainers diary over here? This is the hardest bit in many ways, as you say, without the safety net of SS or 810, and no ketosis to keep you on the straight and narrow. There are many lessons to be learned (and I seem to take my time learning them!) but the people over on this forum are the MOST amazing, warm and supportive people ever. Without their support I don't think I'd have made it this far.
So... if you do start a thread, you'd be very welcome.
Chin up and enjoy the steps, and here's to a slim, happy, healthy future!
