At weigh in tonight, I've put on 2.5lbs over the last two weeks - pretty much in line with what I was expecting given that I've been off plan for some time now.
Looking back through past weigh ins shows that I've only lost 1.5lbs this year. The bigger reality check is that I am now the same weight as I was 9 months ago and that's pretty hard to take.
It's not a case of not believing in the plan - I know it works, because I lost 2.5 stones before slowly putting the majority of it back on. The issue is that I've got out of the food optimising mindset - I no longer question myself about what I'm eating, so it's very easy to veer miles away.
Nobody else can decide what I eat - I'm a (sometimes) rational, (hopefully) intelligent person with my own mind. I just need to get that mind back into the habit of thinking before eating. Easier said than done, but my weight and my health is in my own hands and I still want to get to my target weight - it's just going to take (a lot) longer than I originally hoped.
