He has hepatitis C and has a hard time gaining/keeping weight. He can`t do any anabolics type stuff that will stress his liver. He rarely has an appetite. I am looking for something to give him an appetite and I`m gonna send him(he lives a few states from me) samples of protein powder that I use and a few recipes(adding oatmeal, etc to shakes). He is not a weakling so don`t get the wrong idea that he is frail. He is a mechanic and strong for his size. He is currently about 155 at 6 feet. He would like to be a healthy 180 like he was in high school. Even heavier if possible. He won`t mind gaining a little fat. He is 44 years old.He will be starting a year long chemo type treatment that supposedly wipes out the Hep C but it is rough like chemo is and he needs to gain some weight to be able to handle the treatments. I`m sure the Dr will recommend something, I`m just trying to give him a headstart with any natural stuff that will not possibly hurt him. Any suggestions will be helpful.
