This is personal to me, and right now, too:

I was a great success on Atkins, but a few years ago my health took an endocrine downturn and (proof of concept!) I gained back some of what I lost.

I finally got a grip on it all, which means I can now start losing weight again. None of this is my fault; none of this has anything to do with who I am as a person; and it sheds no disservice on low carb.

In fact, without low carb and what I have learned about health and nutrition here... I wouldn't be here on Earth at all.
