I bet you're referring to my thread in H&H, right? ('cause, you know, everything's always about ME.
I get this too, big time. I have a couple of ideas. I have severe adrenal fatigue. Sometimes I feel better, sometimes I feel worse. But my sensitivity to carbs/sugar seems to correlate with how I feel adrenal-wise.
The symptoms between carb-sensitivity & adrenal insufficiency overlap a bit, so it's hard to differentiate.
When my adrenals have tanked, I feel VERY dizzy upon standing, increased brain fog & more fatigue - more floaters too.
When I eat something carby, I get lightheaded (similar to an adrenal response, but slightly different), heart palps, sweaty & feel "out of my body" - very hard to explain.
The pathway goes like this - leptin is the king of all hormones, in charge of our metabolism. Next down is adrenals, then thyroid, sex hormones, etc.
Leptin & insulin apparently work similarly, leptin-resistance preceding insulin- resistance.
From what I'm reading lately (which has been like putting more pieces in the puzzle), we need to fix our leptin levels wich will also fix our insulin response, which will help our blood sugar which will help our adrenals, which will help our blood sugar (big circle here), which will help our thyroids, etc, etc.
I started a thread on leptin
today. TL posted a good link to a blog & here
are his (10) posts on leptin.
Apparently certain things will block our leptin receptors, like lectins in grains (especially wheat, barley & rye), soy & other legumes like peas, beans & peanut butter. (This is fairly new to me, so my knowledge is REALLY limited. And I don't know much about lectins, either.)
That's my 2 cents for now! BBL.
