I've always eaten "healthy" (as in whole grains & veggies), and never had much of a sweet tooth. Sad that starch is so killer on me now, because I loved my grains! I'd love a nice slice of homemade bread, while candy or soda don't appeal.
I read that article, but I've never been obese or even overweight so I'm not sure it applies to my situation. However, perhaps it's possible that there may be thin people with the same genetic issue--just manifesting as lack of BS control rather than weight gain?
Some years ago, I was investigating diet, relating to a post-viral, poly-arthritic condition affecting me at that time. As I preferred to keep meds to the minimum, I saw a herbalist, who suggested I look at some of the acidic things I was eating. My knee-jerk reaction was "but they're my favourites"; things like oranges, tomatoes as examples. Her suggestion was that sometimes our dietary preferences are actually driven by intolerances, and we can increasingly favour some foods because rejecting them leads to a form of withdrawal. Thus, whilst x food might make us "feel great", it could be we are compelled to eat it, to keep the "fix" up.
Now, I'm not sure I've explained that at all eloquently, but the more I rerad about carb addiction, and carb flu, the more it makes sense.
For completeness, at the time, I eliminates those acidic foods (and drinks) from my diet and matters eased. Of course, being virus related, they may have eased over time anyway, but I'll never know.
Thinking back to that theory helped my focus on my testing when I started off, taking particular interest in my favoured foods. It held up to quite a large degree, but like all intolerances, sometimes we can tolerate a little bit, but a bigger bit seem to tip the balance.
Sadly, it's all a game with no easy answer, aside from testing, testing, testing, recording results and lots of experimentation, over a period.
Good luck with it all.
