Project FODMAP Elimination Blog 1

Jane Cessford – The Fat Foodie

What the project is:

Last weekend I visited the Allergy and FreeFrom Show in Glasgow and I had the pleasure of meeting Lesley Reid, a registered dietitian who specializes in FODMAPs. Lesley was giving a talk at the show on recent developments in the FODMAP world and I’d arranged to have a chat with her afterwards.

Lesley’s talk was a brilliant whistle-stop tour through the basics of the FODMAP diet and I saw a lot of people taking photos of her slides and writing down notes of what foods were low/high FODMAP. However, another thing I noticed which made my heart sink was that when Lesley asked how many people were on or had tried the FODMAP diet and then asked how many had successfully gone through the reintroduction phase (I’m paraphrasing a little bit here, but it’s hard to remember the exact words), there were significantly fewer hands up for those who had reintroduced.

this mirrors a concern I’ve had for quite some time now, that far too many
people are going into the exclusion phase of the low FODMAP diet, feeling the
benefits of cutting out high FODMAP foods, but aren’t going through the reintroduction
phase to identify their own FODMAP tolerance levels.

As a
blogger, I’m in a huge number of groups and channels on social media and I’ve
noticed that a huge amount of people won’t try the reintroduction phase because
they’re frightened that their IBS symptoms will come back.

I can sympathize
with this, I really can, but the problem with staying in the exclusion phase is
that it diminishes the number of foods people will eat which, as a result, has
a detrimental effect on their gut bacteria and can lead to nutritional deficiencies
in the long-term.

When I met Lesley I approached her with an idea I’d had for a while – that she, as a FODMAP trained dietitian, guide me through the elimination and reintroduction phases so that I can identify my new FODMAP tolerance levels while under the assistance of a trained dietitian, all the while documenting my experience of the whole project on my blog. Thankfully, Lesley empathizes with and understands my concerns about the number of people who won’t reintroduce and happily agreed to the project.

Why I’m doing it:

been a couple of years since I put myself through the elimination and
reintroduction phases and I’m noticing that foods I’d previously thought safe to
eat are now sometimes causing me discomfort. Equally, there are foods I’d
previously excluded from my diet in the belief that they were a FODMAP group I
couldn’t tolerate, which I’m now able to eat. As a result, I think my gut
microbiome has changed over time and I strongly believe that doing the
elimination phase again, however difficult it might be, is the best way
forward. Trust me, I’m not doing this lightly!

other reason I’m doing this project is that when I first started the low FODMAP
diet I did not consult a dietitian. This was for a number of reasons:

1.) I
couldn’t afford to see a private dietitian.

2.) The
waiting list to see a dietitian on the NHS is long and it would have taken a
long time to get an appointment.

3.) I
wanted to start ASAP because I was in so much discomfort.

4.) I’m
a qualified researcher, so I knew I could educate myself in how the FODMAP diet
in all of its phases worked before I began the diet.

The main reason I want to go through the elimination diet a second time under the tutelage of a FODMAP trained dietitian, such as Lesley, is so that I can live the experience and communicate to others the importance of going through the elimination and reintroduction phases.

Why I chose to do the elimination and reintroduction phases with Lesley:

Lesley Reid, King’s College Professional FODMAP Qualified Dietitian

I asked Lesley Reid if she would be open to doing the project with me because she trained in the Low FODMAP diet at King’s College London, so she’s entirely qualified as a dietitian to take someone through the intricacies of the FODMAP diet.

also very passionate about the importance of the reintroduction phase of the
low FODMAP diet and shares my concern about the number of people living in the
exclusion phase.

She’s also local (I live in Stirling and she’s got two office locations in Glasgow), so it made sense to use someone close by.

What I aim to achieve:

I want
to emphasise to everyone who follows the low FODMAP diet the importance of
properly going through the elimination and reintroduction phases, so that a
proper understanding of our own FODMAP tolerance levels can be understood with
the long-term aim of being able to incorporate higher FODMAP foods within our
diets to encourage good bacteria growth in the gut microbiome.

What’s happened so far:

This morning Lesley said that she’d be sending me documents to fill out, so that our project can proceed just like it usually would for any of her professional consultations and we’ll have our first telephone consultation on Friday.

I have
to say, she’s so friendly and approachable that I already feel reassured that
she’s going to be the dietitian taking me through this process.

elimination phase is restrictive, so I’d be lying if I said I wasn’t nervous
about going back through it, but I know that it’ll benefit me in the long run
by informing me of my new tolerance levels and improving my gut health.

keep you posted!

    What timing to read your blog. I completed elimination and went Re-introduction. But due to stress over the last few months, and a recent hernia surgery, my IBS has flared up terribly. I thought about beginning illumination again. And wondered if this was wise or not. I will follow along with your journey and begin illumination along with you tomorrow. Good luck.

      Hi Judy,
      I would always recommend consulting a trained dietitian because they’ll be able to look at what you’ve went through and help tailor-make a plan for you, but if you feel you have the skills to take yourself through elimination then perhaps it would benefit you. However, you probably wouldn’t need to stay in the elimination phase for long. Just until your gut calms down.
      I’d heartily recommend arranging a telephone consultation with the FODMAP trained dietitian I’m seeing at the moment, Lesley Reid, because she’s absolutely brilliant! Here are her details: Telephone: (044) 07777640035 Email:
