with you being in the states and the meds coming from india, are you self-diagnosing all this? what are you eating now? why do you want t go low-carb? you're very active, so i don't think 100 gms of carbs is going to fuel you properly. you say your activities are "not intense", but you may want to consider swapping in some yoga or long slow walks instead for awhile -- especially if you suspect adrenal fatigue.
how are your sleep and stress?
magnesium citrate will help with your constipation. you may want to look into something like ashwagandha for your adrenal issues, depending on what else you are taking.
have you tried adding gelatin to your diet? either from bone broth or powdered? collagen helps build collagen, i.e., your gut. foods like oysters have lots of zinc which helps to build collagen too.
the quinoa and the rice are pretty empty, so i'd look more at lentils and other legumes. are there other tubers you can have -- yucca, tarro, sunchokes? what about plantains or green bananas?
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
