Wmr if you are feeling light headed, cold etc it might be worth while going to your Doctor and having some blood work done. Checking you iron, thyroid function (TSH), and serum biochemistry if your doctor thinks it needs to be checked.

If you are indeed anaemic you will proably need a supplement as it is almost impossible to catch up with your iron levels if they are very low just by eating more meat.

For me, my weight goals have been set by Dr recommendation as I need to be at the lower end of healthy for a chance that my ovarian cysts will go away.
