I weight train 5 days a week and my diet was mainly lean meats, fish, egg whites, fruits and veggies and I've been told to stay away from breads and pastas, all in which I'm now beeing told I need to eat because of IBS. Sometimes I am in so much pain I cannot go to work or to the gym. I have recently incorporated more bran and fruits in my diet, though am still constantly constipated and bloated, but found out to my surprise these are the wrong types of fibre anyway! For the last 3 weeks I look like I've been hiding a basketball under my shirt and none of my pants fit. I have switched my diet to more soluble fibres and followed other IBS diets to eliminate the pain but have gained weight. I want to maintain my mass from training, but shed this excess fat I've gained. I need to eat plenty of protein, but eating all that "starchy" foods contradicts everything I have been told in my years at the gym. What kind of meal plan can an IBS sufferer have who wants to build mass and stay lean without pain?
