The 4-Week Programme for a Healthy Gut
Imagine being able to set the course for your health in just a few weeks. Sounds ambitious? Research actually shows that our microbiome is far more adaptable than previously thought. Diet, exercise, sleep and lifestyle influence the composition of our gut flora day by day. And that is precisely where the opportunity lies: what can change can also be actively supported.
Our 4-Week Plan for Your Gut Reset
A healthy gut is far more than a smoothly functioning digestive organ – it influences the immune system, metabolism, mood and even energy levels in everyday life. Supporting your gut means doing something good for your entire body. That is precisely the goal of this 4-week plan.
It is divided into three phases – and each phase has its own purpose. First, it is about giving your gut space and allowing it to recover. Then comes the targeted build-up: the gut lining is strengthened and the microbiome receives its first valuable support. In the final phase, variety takes centre stage – because the more diverse the microbiome, the more resilient the gut in the long run. You don't need radical changes for this – just the right steps at the right time.
Here is how the reset works:
Gut Reset Plan:
Days 1–7: Making Space for Something New
The first days are all about giving your gut a break. Before new, beneficial bacteria can settle in, your gut needs space – and you create that space by cutting out foods that put it under strain: sugar, artificial sweeteners, processed foods and industrial vegetable oils. Depending on your tolerance, you may also want to reduce or temporarily avoid gluten-containing grains and dairy products, with the exception of fermented dairy such as yoghurt, kefir or buttermilk.
Instead, focus on warm, cooked meals, plenty of steamed vegetables and sufficient fluids. Fennel, caraway or ginger tea offer additional digestive support. If you want to go one step further: a longer overnight fasting window of around 12 hours – for example from 7 pm to 7 am – gives your gut valuable time to rest and recover.
Good for your Gut | Better to avoid |
Warm, cooked meals – soups and stews | Sugar and artificial sweeteners |
Plenty of steamed vegetables, fruit as tolerated | Alcohol |
Stay well hydrated – still water, fennel, ginger or caraway tea | Industrial vegetable oils such as sunflower or corn oil |
Regular movement – even a short walk after meals helps | Gluten-containing grains and dairy products – reduce temporarily depending on tolerance |
Plan digestive breaks – e.g. an overnight fasting window from 7 pm to 7 am | Heavily processed foods and ready meals |
Days 8–14: Building Up Your Gut from Within
Your gut has had time to settle – now it is time to nourish and regenerate it. Keep your diet gentle and nutrient-rich: soups, stews, plenty of cooked vegetables and easily digestible grains such as spelt, oats or millet provide soft energy without putting strain on the gut.
Now an important building block comes into play: fermented foods. Just one tablespoon of sauerkraut, fermented carrots or kimchi a day is enough to support the microbiome in a targeted way without overwhelming the gut. Also add one tablespoon of psyllium husks, oat bran or ground flaxseeds daily – simply sprinkled over your food or stirred into a glass of water. Certain micronutrients such as vitamin A, B2, niacin and biotin support the regeneration of the gut lining.
Good for your gut | Better to avoid |
1 tbsp fermented foods daily – sauerkraut, kimchi or fermented carrots | Large amounts of raw food – this can still put strain on the gut at this stage. Not drinking enough |
1 tbsp psyllium husks soaked in yoghurt or water daily – alternatively oat bran or ground flaxseeds | Continue to avoid sugar, sweeteners, processed foods, heavily processed products and alcohol |
Easily digestible, fibre-rich grains such as oats, millet or spelt | Continue with plenty of vegetables, soups and stews, and fruit that you tolerate well |
Maintain regular movement and digestive breaks | |
Vitamin A, B2, niacin and biotin support the maintenance of normal gut mucous membranes |
Days 15–30: Promoting Bacterial Diversity
The final phase is about enriching the microbiome with as many diverse bacterial strains as possible. The greater the variety, the more resilient the gut becomes in the long run. The favourite food of gut bacteria is fibre – also known as prebiotics. Bring variety to your plate every day: sourdough bread, einkorn, emmer, barley, buckwheat, lentils, edamame or chickpeas are ideal companions during this phase and can replace white pasta, rice and white bread.
Bitter compounds also make an often underestimated contribution: they stimulate the production of digestive juices and support the liver. Particularly recommended are chicory, rocket, artichokes as well as dandelion or ginger tea.
Good for your gut | Better to avoid |
Increase fermented foods – try different varieties every day | A one-sided diet – variety is particularly important in this phase |
Prebiotic fibre from emmer, einkorn, sourdough bread, barley, buckwheat, lentils, edamame or chickpeas | Continue to consistently avoid sugar, sweeteners and alcohol |
Resistant starch from cooked and cooled potatoes – ideal as potato salad | Heavily processed foods |
Prebiotic foods such as Jerusalem artichoke, apples and berries | Not drinking enough – fibre needs sufficient fluid to work effectively |
Bitter compounds from chicory, rocket, artichokes and bitter salad leaves as well as dandelion or ginger tea |
What Comes Next After the 4 Weeks
After 30 days, you will have noticeably relieved and regenerated your gut. Your digestion has stabilised and your microbiome has been built up in a targeted way. But the end of the plan is no reason to fall back into old habits – quite the opposite. The past weeks have shown how easily a gut-friendly diet can be integrated into everyday life. Simply keep the best of what you have learned.
