What I would like to explain in this post are the basic principles of the diet we use to balance glucose and insulin levels, to improve insulin sensitivity, hormonal status, fertility, etc. We often refer to it as Insulin Resistance Diet or IR-Diet, but it is also known as the „160g carbs diet„, because we focus on carbs and in the beginning (!) we aim for a daily total intake of 160 gramms. Which of course is only a general starting point and needs to be personalized in each case.

This form of the diet was developed in Hungary by a team of endocrinologists and dietitians, and has a history of about 10 years now with follow-up, documentation and statistics. During these years it has helped numerous patients to improve their carbohydrate metabolism, hormonal imbalances – such as PCOS – and has supported hundreds of women on their journey to become a mother. It is also applied with great results in gestational diabetes mellitus – a medical condition women with insulin resistance or PCOS has elevated risk to develop. This diet is actually part of the lifestyle change to which the study A comparative study between myo-inositol and metformin in the treatment of insulin-resistant women – published in 2017 in the European Review for Medical and Pharmacological Sciences – refers.

I myself have been following this diet since 2012, and do not plan to stop.


Learning this diet is quite similar to learning a new language (I like to use this metaphor): a lot of new info to remember in the beginning, but with time and practice it just becomes natural, a skill. So it might seem complicated at first, but don’t give up. Once you understand the rules, everything will make sense. 🙂 (Yes it actually does. Yes, it works. Yes, there are studies behind it.)

Points to remember:

  1. This diet is based on the WHO’s recommendations on healthy eating – so it will not harm you even if you do not have insulin-resistance.
  2. Aim is to get a healthy, balanced diet, not to exclude food or have too much of some nutrients
  3. Health comes first. Losing or gaining weight and getting fitt is the “side effect” of a healthy lifestyle. 
  4. Basic rules like aiming for 5 portion veggies/day, drinking enough water, having complex proteins at least for the main meals still apply.
  5. Your body needs carbs. Good carbs. Good carbs are the complex ones, which are elevating the glucose – and so the insulin – levels slowly. (This is not always correlating to the glycemic index!) We are not avoiding, but regulating carbs intake.
  6. We limit the intake of carbs – but also have to eat the given amount, otherwise (if we eat too little of them) our carbohydrate metabolism won’t like our diet. 
  7. Most important factors are to get those carbs from QUALITY sources, REGULARLY, and in the appropriate AMOUNT
  8. Meal time (so, eating) should have a start and then an end. Then pause. Do not snack all day long, your pancreas needs to rest between the meals.
  9. We are timing our meals so that there are min 2 hours and max 4 hours between them. This allows your pancreas to rest, but also ensures that you get energy supply regularly. It will boost your metabolism and will help your body to keep glucose level in a normal range and to keep (only) a healthy reserve. Like a Just-in-Time management system.
  10. Things didn’t go wrong in a day – results will also take some time. Give yourself time.


This diet could rather be called „eating healthy„, than a „diet” – for this is not only for a limited period of time, but part of a lifestyle change. This also means that there are no (or very few) strict rules, the diet should become a flexible system which is able to adapt to the changes of life. Life is change itself and there are times when one is travelling, invited for a dinner, training harder, may become sick and can not eat, or one is pregnant, breastfeeding, etc – if the system we build is stable, these situations should not mess up the health results of the lifestyle change.


Choose the good carbs, swap ingredients 

Basically, what we avoid (does not mean that one can never ever eat these, but it’s better to have these only once in a while) are:

Instead of these we

When building up this system, the main focus is on carbs. Of course we won’t forget about proteins, fats, vitamins or calories, but choosing and timing the carbs you eat is in most cases the game changer. So, remember: 

WHAT you eat and WHEN you eat it is almost more important than HOW MUCH you eat. 


Let’s see the “what to eat” part

If the diet would be a language you just start to learn, this would be the “vocabulary”. We categorize food into 3 types: 

  1. Slow carbs
  2. Fast carbs
  3. Not counting as carbs 🙂 (Yes, we won’t count every leaf of lettuce. We just want to have a healthy life, not a nervous breakdown.)


1. Slow carbs

Foods in this category contain complex carbs to fuel your body, but – since they are high in fibre – it will take some time for your body to get energy from them. So your glucose and insulin levels will react slowly, allowing time for your body to balance – what is good for us since our aim is to keep those levels within a healthy range, without jumping too high or falling too low.

Here we count:



2. Fast carbs

Foods in this category contain simple carbs, natural sugars (fructose, lactose). Your body will get energy from them quickly (which is sometimes really needed), but glucose and insulin levels will also react fast. This is true even if the glycemic index (GI) is low (e.g. blueberry) – although the change of glucose level won’t be big (and therefore GI is low), it will be quick and your insulin will (over)react the same way.

Here we count:


3. Not counted as carbs

Foods in this category are not counted as carbs as they contain either not much carbs and/or contain so much protein and fats (which will slow down the reaction to the carbs within) that they will not change glucose level significantly. This also means that if you are feeling unwell because your glucose level went too low, these foods will not really help you out. Watch out: they may be rich in calories, so not counting them as carbs does not mean that one can eat a lot of them! (unless your goal is actually to gain weight)

So, this was the WHAT to eat part. 

Now let’s see WHEN and HOW MUCH to eat

When deciding which carb type (slow or fast) to eat, we follow the natural rhythm of our body’s insulin sensitivity.  The reaction the insulin receptors give to carb intake varies throughout the day. The worst insulin reaction you will get in the morning hours – therefore it will be one of the cornerstones how you choose your breakfast –  and the best one around lunch time.  Following is the basically recommended schedule for the meals with an approximate timeframe – means: you should start your meal within this timeframe, does not mean you should eat this long -, amount and type of carbs they should contain, and a few examples. If you would learn a language, this would be the grammar part, learning how to apply the vocabulary in a correct way:


    1. 6dkg (about 2 slices) of wholegrain bread (in case of carbs content of 50g /100g)
    2. 3 slices of wholemeal toast bread (if 1 slice contains 10g of carbs)

    1. cold cuts / cheese / sausage / egg / cottage cheese / cottage cheese / canned fish / eggplant cream / egg cream
    2. vegetables whose 10dkg contains less than 5g of carbs, eg: paprika, cucumbers, lettuce, radishes. (max. 200g)                       
    3. tea (without sugar, honey)
    4. coffee (without sugar, with coffee cream or sugarfree coconut/almond milk)

    6. Sandwich with vegetables: 8dkg wholemeal bread (50g / 100g carbs) (40g CH) + ingredients that do not count as carbs + 10dkg carrots (8g CH) 


    1. Fruits, eg. 40dkg of raspberries / blackberries or
      • 30dkg apple / strawberry / grapefruit / currant or
      • 25dkg orange or 20dkg mandarin / kiwi / cherry / autumn, apricot, nectarine or
      • 15dkg cherries / plums / pears or
      • 8dkg bananas
    2. Smoothie
    3. 2dl milk / natural yoghurt (10g CH) + frutis containing 10g CH 
    4. Cappuccino without sugar (with 1 dl milk, 5g CH) + 3 Gullon Fibre biscuits


    1. Similar to breakfast 
    2. 2 salty pancakes stuffed with green spicy cottage cheese and salad

    4. Grilled chicken with potatoes + salad


    1. 2dkg of wholemeal bread
    2. 3 pcs of Korpovit biscuits or Finn Crisp
    3. 15dkg of carrots


So, this is the basic structure of the diet we usually start with. Knowing these rules are essential, but not necessarily enough.

The exact amount of carbs may (and will) vary, the needs of your body will change. Your diet should be revised and tailor-made by a dietitian regularly, following up on the changes in your body. The rules (carb types and timing) can be applied also if you are lactose intolerant, vegan, need to avoid gluten, etc. In these cases it needs to be checked if you get enough protein, vitamins, etc.

And do not forget about the other pillars of a healthy life, diet is only one of them. Training regularly, using your body in a way it was designed to – physical activity is actually why you have your muscles in your body – is essential also for your metabolism, hormones and wellbeing. Most of the insulin receptors are on the surface of your muscle cells, even if they are not functioning fully it is always good to have more of them. Still, sports and diet will not work to its fullest if you do not manage your mental and emotional balance. And there might be also a need for proper medical treatment – even if for a period of time – to support the results of the lifestyle change.

With diet you can come half of the way. It’s like filling up your expensive Porsche with quality fuel. The other half comes when you start to use “your machine”.
