EFAs may be your problem.
You sound like you're having a very hard time.
Here's a couple of questions for you.
Do the EFAs you're taking contain evening primrose oil, borage oil or any other form of GLA?
Excess of these can cause a wide variety of health symptoms and most supplements are dangerously high in GLA.
The Zone diet is probably the best out there but you do have to read the books and follow it properly - most people don't.
Generally speaking they eat red meat etc which are warned off if you read the book.
Also one and a half hours of strenous exercise every night could cause the excess production of the stress hormone cortisol which can increase insulin resistance making your problem worse.
Negative emotions and stress can also increase levels of the stress hormone cortisol sabotaging your weight loss efforts.
Poor sleep can also cause the same problem.
I may be able to give you more specific information if you reply to this post and let me know what you're doing now and how you're getting on.
Kindest regards,
