I'm still on it.
I've been stuck weight wise since April, after losing 16 kg, but at least my joints are better now, so I can actually excercise again.
I finally had time to repair my bicycle, and did some shortish training trips of half an hour each (which is the minimum I want to do each day).
But I have to admit, I've tried to change my food intake in a way I can keep up in the future. That means: I eat cake on birthdays (March was real bad: 5 birthdays within 10 days), I don't decline food when I'm invited. I won't eat much of it either, and if there is a choice I'll take the leaner stuff.
Of course that slows down the process, but I'm confident I can keep my weight afterwards. I might be a bit paranoid, but I've seen so many people losing weight, and losing a lot of it, and then putting it on again. I don't want that.
So I'm still motivated ...
