That's not what I said.

You seem to have implied it:

You could also read my comment as "severe calorie restriction didn't work for me that long, not even for weight loss". If I couldn't keep it up longer than a couple of weeks even when I had excess fat, it's unlikely I would be able to keep it up when thin.

I took that to mean that you engaged in calorie restriction sufficient to result in weight loss but were psychologically unable to stick with it. i.e. you were unable to control your eating.

Perhaps you're right. I'll not bother you further.

It's up to you, but we need to be clear about what we are discussing. There's a difference between calorie restriction -- as I have defined it -- and dieting.
