Some people have very low carb diets and still really struggle with insulin / blood sugar problems.
If this is the case for your, consider addressing inflammation and sleep instead of diet. I sometimes see lean, active women with insulin dependent conditions like fatigue and Polycystic ovarian syndrome.
The surprising reason their diets don’t work? Usually either insomnia or chronic inflammation. If your diet isn’t working, [info]try focusing on reducing inflammation[/info].
