Stop all the supplements and stick with real foods. What helped me is this.
I am 5'11" and was 114lbs and went to 155 lbs in a year or so partaking in the raw milk diet and consumed plenty of fresh raw colostrum (not that powdered crap). Guess what, it stuck and there is no way I can or will go back to being that emaciated.
Raw milk diet provides the calories, fat and beneficial bacteria to fix whatever may be ailing you.
