Ok, I'm checking out leptin, mainly because of a possible link with the fibromyalgia and weight gain issues.
The immediate searches produced things about a "Leptin diet". So I hopped over to WebMD (hey, when in doubt, I hit that, Harvard, APA, government and other known sources!) and discovered connections with diabetes, cholesterol counts, weight....
All in all, once again I'm looking at hormonal and brain issues that affect how food is processed, perceived...and when all fails; how it just sort of lands and sits on us.
"high calorie foods may be especially tempting" when leptin's lacking:
"fat hormone leptin may control diabetes"...:
And here is the crucial article:
Leptin FaQ's... with focus on how this hormone affect weight/obesity:
Harvard has many studies, reports, and articles on various aspects of leptin. One which takes time to read but is loaded:
As for fibromyalgia? My thought on this is that the fms link coincides with other links. Saw no indication of how having fms would interact or be especially affected by change in leptin presence in the body. Ah someday... someday!... fms will be reclassified; once a labratory diagnostic can definitively reveal this 'syndrome' it will lose the syndrome classification, be termed an illness... and be closer to effective treatment if not prevention and cures!
Meanwhile, I continue to forage for all that can make me healthier, because when you have fms being as healthy as you can be reduces the symptoms.
