“LIKE FODMAP BUT EASIER?” is the title of the “service evaluation” on the Fast Tract Diet conducted by Mike Sweeney, Registered Dietitian in Leicester, UK and his colleagues enrolling new IBS patients referred by general practitioners in their general dietitian clinics.

What Motivated Mike to Do the Evaluation

  • Patients had to wait at least six months and in many cases longer to see a FODMAP trained dietitian at the time
  • FODMAP can be difficult to follow for a lot of different patients
  • FODMAP training is expensive, which is why in the service there aren’t really a massive amount of FODMAP trained dietitians

What was the Idea behind It

  • If the Fast Tract Diet a viable option or a viable alternative to FODMAP?
  • To identify if a different approach (Fast Tract Diet) works for the same issue of fermentation in the digestive tract

The Big Question for Mike was…

Would the Fast Tract Diet work with a wider group of patients, above and beyond, experimenting on himself (Mike) and above and beyond the patients that he has seen in his own clinic?

The Tool Used for the Evaluation

A validated research tool from King’s College, London which was adopted for this evaluation.


  • After intervention, nobody reported any severe symptoms in any symptom category
  • The percentage of frequent symptoms shrunk
  • The percentage of patients that reported no symptoms grew fairly significantly, as did the percentage that reported only occasional symptoms
  • No one is reported any tolerance issues of any kind

Adherence rates to the Fast Tract Diet

  • 27% of the patients, or nine out of 33 reported sticking with a diet all of the time
  • 36% reported sticking with the diet most of the time
  • 27% reported sticking with the diet just half of the time
  • Only 9% reported sticking with the diet not at all
  • The Fast Tract Diet definitely seems to be well tolerated
