The yeast free diet (feast without Yeast):

on the other hand warns against low carb diets, suggesting that excessive meat results in a more debilitating and pathogenic intestinal flora long term. They do recommend restricting certain starchy carbs depending on the level of the diet followed (with gluten and dairy restricted in one of the more advanced levels if no benefit is felt earlier).
The diet was developed by a psychiatrist and a National Cancer Institute researcher with access to US army germ warfare labs. They developed it to help their autistic son.
The four most important things to eliminate early on are:
Vinegar
Barley malt
Alcohol
Coffee (often mold contaminated and it excites the intestinal track disrupting normal function which includes inhibiting various pathogenic species)
Also, according to this study, drinking coffee was associated with an increased prevalence of active H pylori infection:

This works for most people (I think 90%).
Other foods eliminated in later stages include aged cheese, chocolate (dried with fungus), many nuts, peanut products and corn and anything made with corn.
Beef is recommended over chicken because chicken fat often has mold related toxins in it from chickens eating cottonseed and other often mold contaminated foods.
The book recommends nystatin to help eliminate yeast, but oil of oregano might even be better.
