Also, be sure you are well supplemented with Vitamins A D E K. If for example you are deficient in Vitamin A, and the higher metabolism exhausts Vitamin A, then you may run into some deficiency crisis. Ditto with the B Vitains. I'll have B-complex vitamin supplementation as well. Zinc too. I just don't know what you're eating and what you're deficient in, so it's best to be prepared and have these vitamins and minerals on hand
