Okay so I know many foods high in protein, and many foods high in carbs, but I think I need to get in more calories. I have IBS so unfortunately I cannot always eat 6-7 times a day, I pretty much get sick once a day. Yeah it sucks, but i work my way around it. I'm looking for foods/drinks that are high in calories and will help me gain weight. Right now im 21 yo, 6'0'', 175 lbs. I'm looking to gain around 15 pounds to start. I'm always doing the 5x5 linear progression workout. I think my biggest problem is diet though. Any good food advice, especially quick foods, is greatly appreciated. Thanks guys/girls.
