    I just finished reading the Fast Tract IBS book. While the theory relating carbohydrate fermentation to SIBO seems like a logical extension from the FODMAPS diet I’ve been following for a while, I feel like some other common IBS irritants have been glossed over without discussion.

    First, an intolerance to fat. Fat may not contribute to SIBO, but it certainly appears to affect a lot of people with IBS! It seems irresponsible to point so many IBS sufferers to a diet plan that includes high fat foods without at least warning of its potential to cause spasms, cramping, and diarrhea in some people! Is there a link between these symptoms and SIBO? With reduction in SIBO, can one expect to better tolerate and absorb fat?

    Vegetables, especially raw, are commonly linked to gas and other IBS symptoms. Again, low FP vegetables may not lead to SIBO, but they lead to gastric distress in a lot of us! A leafy salad is the last thing I could imagine eating at a meal, especially on an empty stomach.

    I think a wide reaching IBS solution needs to acknowledge ALL of these potential dietary problems. There is mention in the book of underlying physical problems that can contribute to SIBO, but most of us with IBS have been told we don’t have anything physically wrong with us. If I’m not suffering from another medical issue, then why do fats and raw vegetables still bother my stomach on this diet? The problem with every IBS treatment strategy I’ve read about is that it clings too dogmatically to its own novel solution without admitting that it doesn’t actually address all of the potential dietary causes of symptoms. The SCD, GAPS, FODMAPS, and Fast Tract diets all have merit, but they’re also not going to fix every IBS sufferer’s problems even though they’re all sold as the NEW CURE FOR IBS! Obviously we’re still trying to figure out what exactly “IBS” is, but until we do know, people shouldn’t claim to have THE cure. Mr. Robillard’s theory seems like a great leap forward for squashing SIBO, but SIBO doesn’t seem to be the whole equation for a lot of us with IBS.

    If you can, please comment on the relationship between IBS and an intolerance to fats and “rough” vegetables (e.g. leafy greens and raw vegetables) and whether eliminating SIBO has the potential to alter a person’s response to these foods. Thanks.

    Oh, and there is also little warning of the harm that consuming a lot of high GI foods can cause! Promoting the consumption of high GI foods without explicit mention of balancing them with lower GI foods seems a little reckless.

    Hi, Wontstopeating!
    I don’t expect perfection from any diet or theory! As a result, I use a combination of what makes the most sense to me: I like the Fast Track theory and fp charts & calculations, I like GAPS and others that urge bone broths, and I’m finding some of the other suggestions re: supplements very helpful. Everyone is different, everyone needs to take into account their own individual bodies and reactions/sensitivities.
    Fast Track doesn’t recommend a lot of high glycemic foods, but recommends keeping total carb consumption down. It also says diabetics need to be very careful with the high glycemic foods.

    Agree with 49Barefoot that Dr. Robillard recommends keeping carb counts at 75 grams or less (I believe) per day, which is very conservative when compared even to standard guidelines for diabetics. He also advises if people have blood sugar issues, to avoid the higher GI foods and replace them with options that are safer. The intro diet has 1/2 cup of jasmine rice (and NOT even every day!). And the other higher GI foods are not that frequent.

    You are right that fat does not cause SIBO. I can’t answer completely why some people have a much harder time with fats. There could be several underlying physiologic reasons. One of them however does have to do with SIBO itself, as I am sure you have read that the overgrown bacteria are known to deconjugate bile acids which are needed to digest fats. So it would follow that as the SIBO is better managed, there is more bile available to do its job. I certainly have seen my digestion slowly improving. Digestion of any fiber in a gut that is malabsorbing its food is going to be tricky, regardless of the diet you follow. The intro diet in this book does include raw salads. However, it is not a stone tablet but a guideline. I personally looked at the allowable foods and portions of foods (this is key) for the first two weeks in order to build my own intro diet.

    Yes, veggies can drive gas symptoms, which is exactly why Dr. Robillard suggests controlling the amounts of low FP veggies that one consumes in a day. More than a cup of cabbage will create gas for me, but less than a one cup serving will not, especially if I calculate it in to my total FP for the day.

    My concern since following some of the SIBO forums, is that many people expect a quick fix or perfect diet to manage a digestive scenario that took a lifetime to create. There are a lot of things that need to be in play to rebuild one’s gut health. Diet should be central to this, and could take quite some time to have the desired effect. I was impressed with the dramatic symptom relief I first acheived when following this diet, and further improvements are happening, but now at a slower pace. I think it is difficult to try to compare FODMAP, SCD and the Fast Track Approach, as they are quite different since FODMAP and SCD are qualitative, and Fast Track Diet is quantitative. Both might be usefull, but I find Fast Track Diet more inclusive.

    FTD is also much more flexible than other diets. Most say “don’t eat X”. FTD gives you the information to figure out how much X you can have. It may be only 1-2 oz, but if you want X bad enough you could eat a little with other foods.
