Food intolerance

In 2016 I wrote a post in which I mentioned that I have been diagnosed as a fructose intolerant. It was quite a journey to get to the point of the diagnosis.

Before the diagnosis

Back in 2004 I followed a diet where I lost so much weight that I was really skinny, and even now still when I see the photos, I don’t like my face. It was just too thin. The diet I followed allowed you to eat all foods, but there were specific combinations you had to make, and you always had to weigh your food. I went to a club to be weighed, and they called it a lifestyle, but in the end it was nothing more than a diet.

One part of the diet was to eat brown bread for lunch, and a piece of fruit. Obviously, also to eat breakfast. Eating breakfast is the only good thing I have taken from the diet, as before that I never did it. Once I stopped with the diet, and already had started to gain weight again, I kept on eating bread during lunch, and one or two pieces of fruit.

It must have been in 2007 or 2008 that I had a couple of weeks where I felt nauseous, until one day I realized it must be the cappuccino I was drinking that came from the coffee machine. I stopped drinking it, and the nausea disappeared. Then I noticed that whenever I drink Cup-a-soup, I was nauseous again, so I stopped drinking that. For some time it went okay, but then I started bloating after lunch. Every. Single. Day. I had no idea where it came from, as I was really eating healthy. I tried different combinations, but to no avail.

By now we were somewhere in 2011 or 2012 and I was still trying to figure out what was wrong. Internet was my friend, and somewhere towards the end of 2012 I sat at the doctor and told him that I think I am lactose intolerant. He said that he didn’t agree, but to ease my mind he would send me through for a test.

It was negative.

I went back to him, as I still didn’t feel well, and since he knew my mental state (I had just returned to work after a burnout), he said he thought it was more stress-related than anything else, and he sent me through to a dietitian to figure out which foods I can eat and which not. One of the first tasks the lady gave me was to keep a diary of what I eat, and how I feel after eating. From this we discovered that my bloating and tummy ache always started after the lunch.

That’s when she decided to send me through for a fructose intolerance test.

The diagnosis and what it meant

Just like with the lactose intolerance test, I had to drink a cup of very sweet stuff, and then had to stay at the hospital for the four hours after. Every hour they took my blood pressure and listened to my heart, and they asked me how I felt. Not even an hour after I drank the stuff, I was nauseous, and into the second hour, my tummy was majorly upset, to the point of diarrhea. The test was positive. I was fructose intolerant.

The result of the test meant that I had to be careful with the amount of fruit that I eat. That’s what the dietitian told me. Now she is an old-school dietitian, following the rules that the national nutrition center has set, which meant my diet would include everything, and yes, fruit too. She tried to push me in the direction of losing weight, and soon I was so done with all her patronizing words, that I stopped going to her. I would figure this out on my own.

Changes I made

I stopped drinking coffee, because milk made me nauseous. I stopped eating fruit, because it made my tummy ache. I still ate carbs, because I had no idea that it was bad for me. Through all this, I gained weight, and I felt increasingly bad about myself. But the main thing was that I could just not figure out what changes I had to make, other than no more coffee and no more fruit, to stop the bloating I had every afternoon. Seriously, the ladies on the other side of the office could hear my tummy rumble, every single day.

Then I heard about the LCHF lifestyle.


Low Carb, High Fat. Eat more fat? That went against everything and anything I have ever learned during the previous diet I followed, and what people around me believed. It took quite some time to figure out how to do it, as in the beginning I still ate too many carbs, and at the same time I ate more fat, which meant I gained more weight. I joined a Facebook group that had extensive writings about the LCHF lifestyle, and started changing my ways.

Within the first week my tummy ache was gone. The bloating was gone. This was such a relief! It seemed I have finally found a way to stop the bloating, and at the same time, I started losing weight. I was so very ready to lose weight.

I never was hungry. Seriously, never. Yes, there were times I craved some things I wasn’t supposed to eat, but this was why I made sure that I had one cheat day every week. Mostly on Saturdays, but when I knew I would go to the spa with my friend, like I am going to do tomorrow, then that is my cheat day, and the Saturday will be strictly LCHF. This works for me, not only to make me feel better, but also to lose weight.

Golden rule

A golden rule I follow — and which I have learned from the Facebook group — is that all food that have 5 grams of carbs and less per 100 grams, fit perfectly in the LCHF lifestyle. The only exception is veggies, as those are good carbs.

If you search the Internet, there are more than enough lists telling you which foods to avoid when you want to follow this lifestyle.


I am in no way an expert in the LCHF lifestyle, but I can always try to help if you have any questions regarding this way of living. Just leave them in the comments section, and I will get back to you!

  1. This is really interesting, thanks for sharing. I guess that once you know you are intolerant you can work to try to eliminate the fructose.

    As I’ve mentioned before I believe the way for me to lose weight now is through a lower carb diet. I don’t however want (if I can help it) to count calories or indeed carbs. So for now, I am trying to follow something close to LCHF but without counting everything. If my weight loss stalls I may think again.

  2. I am so glad you wrote about intolerance – I have suffered from them too and will write about it latter in the month. Very interesting how you managed to figure out so much by listening to your body – makes a lot of sense. I am not a fan of the low fat diets – it tends to mess with the system as we need fats for our brains to function among other things. And if you eat enough good fats they will balance out the bad fats, so your body stays in control of them – Thanks so much for writing this Marie and linking it up

  3. I actually haven’t heard much about fructose intolerance. It is really good that you were able to find out that is what it was through. I have tried most of the different sorts of diets – crackpot ones I made up myself as well as low far, high fat, low carb, no sugar, fasting etc. I find that most work to begin with but then seem to stop. I guess different things work for different people and it is really good you have found one that you feel good on. It always surprises me with topics such as this how many people are affected and to what extent. Thank you for sharing ?

  4. What percent of your daily intake is carbs, fats, and proteins? My husband is doing keto, and taking me along for the ride. I’m not as strict as he is…I’ve been averaging about 20% or less carbs and 60% or more fats. Yesterday I had 61 grams of carbs/19%, which is way lower for me than usual. What works for you?

    1. I have my goals set at 1200 calories (I had to put it in there to be able to put in the rest), 30g carbs (10%), 75g protein (25%) and 87g fat (65%) and it seems to work the best for me. Back in 2016 my carbs were set to a maximum of 20grams, which was 5%. Does this help?
