answer:Of course! In fact, working out will boost metabolism and burn fat. IBS is a condition with the stomach organ and not so much the actual stomach. People can reverse IBS with a conscious diet as well. People with IBS generally can’t handle processed foods, gluten, dairies, alcohol, highly acidic foods/juices/drinks, or spicy things. I’ve battled IBS, sometimes I win, but other times I cave into spicy, and processed foods :X
