I saw my buddy I havent seen in a few months and he gained about 15 pounds as well as become pretty ripped. I asked him what he did and he basically said he ate alot. I asked him what his diet was like and he said whatever he wanted which included alot of junk food. How is this possible? I have kept reading about eating healthy fats and now I see this guy who eats more junk food than the average guy and is ripped as hell. He did take some protein and weight gaining supplements but still. Any reason how this is possible?
