Thanks for the informative article which I found from @chekohler's entry for the Pay it Forward Curation contest.

One of the things I've learned over the years is that kcal in +/- kcal out doesn't necessarily = weight gain/loss. For me, that sort of broke when I started struggling with my thyroid - which, of course, is directly related to metabolism. I have managed to correct it now through diet, but due to genetics, I think I will always struggle with my weight.

Thanks again for your informative post - I hope you will write many more.
