I was diagnosed with IBS-C in 2001. The intermitting years have been very painful: mostly severe abdominal spasms, often accompanied by nausea/sometimes dry heaves. Along the way I discovered the IBS diet as described by Heather von Vorous on her website. I am grateful to this diet for the help it provided along the way. However, recently I decided to try accompanying my husband on his Ketogenic diet, even though it is practically the opposite of the IBS diet I had been trying to stick to. My IBS diet: low-fat; high soluble carbs. My new Ketogenic (Keto) diet: high-fat; low carbs (cut out sugar and white flour). To my surprise and delight the keto diet, as long as I stick to it, has put my IBS in remission! Feel free to contact me with any questions.
