Well, I started 5:2 18 months ago, nice & easy to remember that I reached my target weight 6 months later, so that now makes 12 months on maintenance
My weight loss was a classic 1lb / week & achieved through a rigorous classic 5:2 with an occasional 16:8 if I needed it (due to excessive dining out or similar).
Maintenance started with roughly 1 5:2 a week & gradually moved towards a 16:8 instead as 5:2 was causing me to carry on losing weight which I didn't want.
I weigh EVERY DAY & know that without doing that I would not maintain. AS SOON AS I go anywhere over my target weight I 16:8 or 5:2 to get myself back in line, although it's now pretty rare as I am clearly naturally eating less & enjoying skipping an occasional meal just because I don't need it.
I am thrilled to have been at target for 1 WHOLE YEAR, something I have never achieved before in my life. I'm also very happy to know that I have the tools to stay there.
Couldn't have done it without 5:2 & this fabulous forum
