A common misunderstanding concerning the low FODMAP diet is that it is lifetime diet (similar to the strict gluten-free diet that individuals with coeliac disease must adhere to for life).
Well, this is far from true. A strict low FODMAP diet should be trialed under the guidance of a dietitian, for a period of only 2-6 weeks. People who experience symptomatic improvement during this strict phase (our research suggests that around 75% will) should then enter a re-challenge phase, during which a dietitian assists the reintroduction of FODMAP containing foods, in a systematic manner, to determine your individual level of tolerance to the various FODMAP subgroups.
