Fodmap and weight loss

Hello all, well i started to lose weight 4 months ago, put it down to my IBS, doctors not bothered. Well eventually started to gain weight and it levelled off. I never understood why i was losing as i had a hysterectomy some years ago and trying to keep my weight down was the big problem.

Now, been on Fodmap two weeks and despite eating virtually morrning, noon and night and eating more food my weight is still steadily decreasing although my ibs symptoms have massively improved which i am really pleased about as i am now scared of having BM because i have a massive caruncle which bleeds a little when i have a BM.

Has anyone else lost weight on Fodmap.?

  • Exactly the same. Am eating very well but have lost over 3 kilos over 4 months.

  • Yep been on it a month and have lost half a stone. Great news as the worse my IBS got the fatter I got - just hope it continues as now hopeful I'll get back to my normal weight over winter and that coupled with the difference FODMAPS has made to my life already I might feel like a normal human being again..................

  • What's the Fodmaps diet?

  • Salt and sashapet, thank you for replying, feel better now. Was in a panic because thought it was abnormal. After years of starvation diets and losing next to nothing to suddenly be eating continuously and lose weight is really weird.

    I have reduced sugar a lot and cut out additives so makes me think that they are the nasties. It is an amazing diet.

    If you havent already tried it please do. I got a lot of help on here when it was first suggested to me, there are people on here who are really knowledgeable about it and will really help you.

  • I too lost weight initially when I was doing FODMAPs. Managed to stabilise it by eating corn tortillas at lunchtime instead of crackers and always included potatoes in my evening meal.

  • I have been on the diet for a couple of weeks now and noticed the benefits very quickly (I was diagnosed with ibs following radical radiotherapy for cancer of the cervix six years ago) so the relief from symptoms has been a joy!

    However, I too have started to lose weight and it's weight I can't really afford to lose. I never really regained my normal weight following treatment despite eating 'normally'.

    I've made an appointment with my GP next week to hopefully be referred to a dietician, as I feel I need supervision when on the diet. Does anyone know what the approximate waiting time might be? I live in London.

  • The good news is that dieticians in London know about FODMAPS. You might be able to self-refer - I did (although I don't live anywhere near London). Phone up Guy's Hospital Nutrian and Dietetics dept and see what they say.

  • Thanks. I will give that a go :)

  • My attempt at the low FODMAPs regime has reduced the ab pain I get but not the constipation. Debating whether to eliminate wheat completely or dairy. I don't really want to. I've been referred to a nutritional doctor. I'll keep you posted. My low weight is giving me saggy skin and bony butt :( !

  • I was prescribed Macrogol sachets to help with C because i have slow movement through bowel. taking some medications may have caused C to get worse. Macrogol plus FODMAP diet - esp no wheat or gluten and definitely no foods raised by yeast. my weight has stabilised, no bloating and feel good.

  • List of FODMAP trained dietitians here

    I've lost a few pounds since I started FODMAP diet in July. Will be starting Challenge phase next week under supervision of my NHS dietitian. Highly recommend this book.

    I find red and yellow sweet peppers and cherry tomatoes help with the constipation. Although the NHS version of FODMAP diet allows spelt, I suspect it has been a problem for me so I have dropped it for the last few days and have seen further improvement. Will be speaking to dietitian about gluten sensitivity/intolerance.

  • I have lost loads of weight...didn't have much to lose in the first place so have been worried...still get flare ups ESP if I eat too many carbs like potato and rice...not sure what else to eat to keep up my weight! :-(

  • I hope to lose weight! So far I am putting on weight doing one week of the Fodmap diet... I think this has to do with the amount of cheese I am now eating which I never really used to.. also going to the gym 4-5 times a week I guess its muscle building.. but so far Ive put on weight. Heres a recipe you can try that is oh so tasty, packed with fodmap friendly veg 'n protein and high in calories! Hope that helps you guys who want to put on weight, good luck xx

    Gluten-Free Butternut Squash & Feta Pie

    Serves 4 - 6

    Shortcrust Pastry:

    275g gluten free flour (I used Doves Farm White Self Raising Blend)

    150g butter, room temperature

    2 large free range eggs, beaten

    Pinch of salt & pepper

    Extra egg for glazing pie


    1 butternut squash, cut into 8 pieces

    1 red bell pepper, de-seeded and sliced

    1 courgette, sliced into thin rounds

    1 clementine or 1/2 orange

    50g Feta cheese

    15g pine nuts

    20g sliced almonds

    2 - 3 tsp olive oil

    1 tbsp cumin seeds, partly ground

    1 tsp smoked paprika powder

    1 tsp cinnamon powder

    1/2 tsp garlic & coriander powder

    1/2 tsp ginger powder

    1 tsp dried thyme

    Salt / pepper

    Pie dish

    1/6 of pie = 510 cals


    1. Preheat oven to 180c. Cut squash into chunks and roast with little olive oil, salt, pepper and paprika in oven for 40 mins until soft and caramelised. Take out to cool once cooked.

    2. In the meantime make the pastry: Place all the ingredients into a food processor and blend until smooth. Bring the mixture together into 2 balls. Flatten into rounds and wrap in cling film. Chill in the fridge for 30 minutes.

    3. Pan fry courgette slices in a tsp olive oil and put aside. Pan fry sliced red pepper in another tsp oil adding partly ground cumin seeds for a minute, and then squeeze juice of a whole clementine and cook for another min or 2. Set aside.

    4. Dry roast pine nuts and almonds. Set aside.

    5. Mash the cooled squash having removed the skin and seeds. Add cinnamon, ginger powder and garlic n coriander powder, salt n pepper. (Optional: Gather the seeds and put back in the oily pan and in the oven to make pop corn tasting roasted seeds for a protein snack - yum!)

    6. Roll the pastry rounds between two sheets of clingfilm until fits size of pie tin - one slightly larger for the bottom crust and one smaller for the top crust. Cover the bottom of the pie dish with the bigger layer of pastry, trimming the edges and filling in any gaps or cracks.

    7. Fill the pie with the filling - first layer of courgette, then peppers, then sprinkle the nuts and crumbled feta, finally adding the spiced squash. Sprinkle the thyme on top.

    8. Put a little egg around the edges of the pastry and add the top pastry to cover the pie. Brush the pastry top with egg.

    9. Bake for about 35 minutes until golden and crispy (I put in top of oven for about 10 mins and bottom for the rest with foil over once I liked the colour of the top).

    *** Enjoy with a fresh green salad with balsamic vinegar dressing. :) ***

  • I was diagnosed with post infectious ibs about four months ago, after almost 12months of constant doctor and hospital admissions. I was told to stay on a low fodmap diet and maybe in two years id be back to normal. Well ive done exactly what ive been told to do and have gone from 57kilos to 43 kilos. I have only just come out of hospital again, this time with malnutrient. the stomach cramps and crippling pain and nausea are constant. Has anyone else out there had the same reaction to a fodmap diet?
