Yes, although it took a good 50 + years to get to the lovely stable gut I have today.
Over the years I have tried everything and although some things caused temporary relief, they just didn't work long term.
I eat predominantly fruit and vegetables, with a small quantity of fish (2-3 servings) each week and alternative protien sources such a quinoa, lentils etc. I eat cheese, but again only in small quantities and take a daily probiotic drink. I drink 1-2 coffees a day and the rest of the time just have water. I also have a square or two of 85% Chocolate if I want it, but eat no other processed sugar at all.
The breakthrough for me came when I was feeling particularly ill after a bout of gut issues. I did masses of research, read the book 'Gut' and realised that I had to do something to resolve my gut problems. They were beginning to dominate my life.
The first things I eliminated were processed sugar and carbs (bread, cake, biscuits etc) I felt immediately much better. I also stopped getting the constant food cravings I had lived with for years.
I then challenged whether I needed the quantities of protien I was eating at each meal and my overall portion sizes. I also reduced my dairy intake.
Finally I tackled other processed foods and eliminated everything that caused issues. I can eat Pesto, tomato / pepper pastes and things like Marmite, but struggle with Hummus and many canned / jars of sauce etc.
In all it took about two years to get to where I am now. Things like the removal of carbs / sugar had immediate effects, but it took me ages to works out that Hummus and some other processed foods caused me problems.
I am not a food bore, rarely talk about what I have done, doubt if friends even notice when I eat out and use Pinterest as a source of fab recipes if I am entertaining. In my head nothing is off limits, but I just have to accept that if I eat bread or a large ice cream, I will not feel so great the next day.
Friends do comment on how well I look, one side effect has been a gradual reduction in my belly fat, and I have masses of energy. I have also impressed my cardiologist. I have heart issues and have seen a reduction in Cholesterol and blood pressure since I made these changes.
