So - especially considering that your hypothyroidism is more subtle and thus possibly more reactive to environmental factors - maybe increasing your carbs somewhat isn't such a crazy idea.

I know nothing about it - but it's possible that's some of what she's going for.
For some women, very low carb doesn't work well (nor does intermittent fasting), and by low carb I mean <60 grams per day. There are other good nutrition-dense carb vegetable sources than grains however, so those are worthy of exploring if you want to avoid them. I don't eat grains of any kind, and I've no problem consuming enough carbs to fuel my energy needs for my activities. I no longer do endurance cycling however, I don't know how well that would have worked for me.
