But i am not attempting to eat very little. It is just my appetite that is low.

I supplement with methylb12, folinic acid, P5P. As well as magnesium, B vitamin Complex, manganese, molybdenum, zinc. I also have just started getting again Intravenous Vitamin C 30g with B vitamins and trace minerals and glutathione. I also use Hemp Seed Oil, evening primrose Oil and extra virgin coconut oil for EFA’s. + Use an Aminoplex freeform amino acid supplement + Acai berries powder in a concentrate. So i think my nutrition is decent.

I should also mention that i have a mild chronic gastritis for whatever reason.

Although In 2005 i went from really overweight about 125kgs to underweight at 70kgs. I then had struggled with inability to lose weight 2007 when i was about 105kgs and doing bodybuilding when i had high T.S.H, and significantly elevated thyroid peroxidase antibodies. I tired T4 100mcg which the endocrinologist gave me but after a week i felt even worse than before then i got off it.

Doesn’t low cortisol cause poor appetite?

and what other hormones influence BMR?

And why is it that we have those skinny people who eat 6 times a day fast food and don’t gain weight and a person similar to them but who eats 1 meal a day…. is it all hormones and diet or is it genetic
