Diet in Prediabetes: Tips for a Healthier Lifestyle

What is prediabetes?

Prediabetes is a silent precursor to possible diabetes and represents a serious condition that often goes unnoticed. Medically, this refers to a condition in which blood sugar levels are persistently above the normal range, but not yet high enough to diagnose type 2 diabetes. The medical term for this condition is diabetes mellitus. Typical signs of prediabetes are often absent, although non-specific warning signs such as increased thirst or fatigue may occur. Blood glucose is measured for diagnosis, with values given in milligrams per deciliter (mg/dl).

Prediabetes therefore means: sugar metabolism is already impaired, and it is a serious condition. This phase is an important opportunity to actively counteract it and protect your health in the long term. With targeted adjustments in diet, exercise, and lifestyle, prediabetes can often be reversed.

Causes and risk factors

Why does prediabetes develop in the first place? There are several reasons:
The risks of untreated prediabetes are significant for many people, as it can lead to serious complications.

Overweight, especially abdominal fat, is one of the biggest risk factors. Fat tissue in the abdomen releases pro-inflammatory substances that weaken the effects of insulin.
Lack of exercise reduces the sensitivity of muscle cells to insulin. Those who exercise little are more likely to have elevated blood sugar.
Unhealthy diet, rich in sugar, white flour, and saturated fats, throws sugar metabolism out of balance.
Family history: If parents or siblings have type 2 diabetes, the risk increases.
Age: The probability of prediabetes increases from around age 45.
Chronic stress and certain ethnic backgrounds can also increase the risk.

Certain people, especially adults, are more frequently affected by prediabetes. Prediabetes usually develops gradually and often goes unnoticed until a diabetes diagnosis is made during a routine check-up. The risk of developing type 2 diabetes from prediabetes is significantly increased without timely prevention.

People with prediabetes: Challenges and opportunities

For many people, a prediabetes diagnosis is initially a shock – after all, it is a precursor to type 2 diabetes and signals an increased risk of developing diabetes. But for people with prediabetes, this message also holds a great opportunity: they have the power to actively counteract it and sustainably improve their health.

One of the biggest challenges for people with prediabetes is to honestly question their own lifestyle and establish new, healthier habits. This means taking a close look at your own diet, keeping an eye on your blood sugar levels, and exercising regularly. Especially in a hectic daily life, it is often difficult to break old patterns and consistently work on preventing type 2 diabetes. Dealing with stress and the uncertainty of how great the personal risk really is can also be stressful.

But the good news: prediabetes is not destiny, but a wake-up call. Those who take action now can significantly reduce the risk of type 2 diabetes – studies show that targeted measures can reduce the risk by up to 70 percent. Even small changes, such as consciously choosing whole foods, scheduling exercise sessions, or reducing stress, often quickly show positive effects on blood sugar levels.

It is important not to get discouraged and to take things step by step. No one has to change everything overnight. It helps to set realistic goals and consciously recognize successes – such as more stable blood sugar levels or more energy in everyday life. Exchanging ideas with other affected people or receiving support from professionals can also motivate and provide reassurance.

Regular check-ups with the doctor and monitoring your own blood sugar levels are valuable tools to see your own progress and receive the right recommendations for preventing type 2 diabetes. In this way, prediabetes becomes an opportunity to take your own health into your own hands and protect it in the long term.

With the right attitude, a little patience, and the right measures, people with prediabetes can not only reduce the risk of type 2 diabetes, but also significantly increase their overall well-being and quality of life.

Diet and exercise: The most important levers

A balanced diet is the key to stabilizing blood sugar and avoiding blood sugar spikes. Carbohydrates and carbohydrate-containing foods directly affect blood sugar levels – especially fast-digesting carbohydrates cause blood sugar levels to rise rapidly, while high-fiber carbohydrates ensure a slower rise. The following basic rules help with this:

Whole grains instead of white flour: Whole grain products provide fiber that causes blood sugar to rise more slowly.
Plenty of vegetables: Preferably a colorful mix. Vegetables provide important vitamins, minerals, and antioxidants that counteract inflammation.
High-quality protein sources such as fish, lean meat, eggs, legumes, or plant-based alternatives support metabolism and keep you full longer.
Healthy fats from nuts, seeds, olive oil, or avocado are beneficial for the heart and blood vessels.
Sugar and highly processed foods, on the other hand, should be the exception.

When choosing foods, it is important to pay attention to their impact on blood sugar, your own blood sugar level, and the development of blood sugar levels. A conscious dietary change and switching to a blood sugar-friendly diet are central measures to reduce the risk of type 2 diabetes. A tip: An example of a healthy meal is a salad with chickpeas, avocado, whole grain bread, and olive oil – this combination keeps blood sugar stable and supplies the body cells with important nutrients.

Regular exercise is at least as important. It improves the insulin sensitivity of the body cells and the entire body, which has a positive effect on the blood sugar level. Endurance training (e.g. jogging, walking, cycling) and moderate strength training, which strengthens the muscles and burns more sugar in the long term, are particularly effective.

A consistent lifestyle change, consisting of a dietary change and more exercise, is crucial to prevent or treat prediabetes. If these measures are not implemented, the consequences of untreated prediabetes can be serious – including damage to the kidneys, nerves, and blood vessels, as well as an increased risk of further illnesses.

Stress reduction and sleep: Often underestimated

Stress releases the hormone cortisol, which raises blood sugar. Chronic stress can thus promote the development of prediabetes in the long term. This is why stress management is a central building block:

Relaxation techniques such as yoga, meditation, or breathing exercises help lower cortisol levels.
Regular sleep is also important: Less than 6 hours of sleep per night is proven to increase the risk of insulin resistance.

Even small adjustments – such as an evening walk or consciously switching off your phone before going to sleep – can help.

Symptoms and diagnosis: Often unnoticed

The insidious side of prediabetes: It usually causes no symptoms. This is why many affected people are unaware of their increased risk for a long time. Typical signs that may indicate prediabetes are often overlooked or dismissed as harmless.

Some people notice non-specific symptoms such as:

Fatigue, lack of energy
increased thirst
frequent urination
occasional blurred vision

Regular preventive check-ups and blood sugar measurements are therefore important – especially if risk factors are present. An early diabetes diagnosis makes it possible to take timely measures and prevent the progression of the disease.

Prevention and treatment: Taking action pays off

A targeted dietary change and lifestyle change are crucial to improve blood sugar levels and reduce the risk of type 2 diabetes. In some cases, however, the use of medication may also be necessary if lifestyle changes alone are not enough. If prediabetes remains untreated, serious consequences such as damage to the kidneys, nerves, and blood vessels can occur.

A healthy diet with less sugar and more fiber improves insulin action. A tip: Replace white bread with whole grain bread – this makes the dietary change easier in everyday life.
Regular exercise helps transport excess sugar from the blood into the muscles. Exercise also increases the insulin sensitivity of the body cells and improves the metabolic health of the entire body.
Even weight reduction of just 5-10% can be enough to bring blood sugar back into the normal range. An example: Those who walk for 30 minutes every day and avoid sugary drinks can already notice positive changes after a few weeks.
Stress management and sufficient sleep stabilize the hormone balance.

All of this is not only useful for people with prediabetes. Those who take care of their health early also reduce their risk of cardiovascular diseases and other lifestyle diseases.

Collagen and porridge: What can they contribute?

Collagen – more than just good for skin & joints

Collagen is a structural protein found in skin, bones, and cartilage.

Collagen provides high-quality protein that causes blood sugar to rise more slowly at breakfast – e.g. when stirred into porridge – This can have a positive effect on satiety and reduce cravings.

Collagen fits perfectly into a prediabetes-friendly diet. A spoonful of collagen powder in breakfast porridge can therefore support not only skin and joints, but also metabolism.

Porridge – the perfect start to the day

Oatmeal porridge is a great option for people with prediabetes:

Oats contain beta-glucans, soluble fibers that can delay the absorption of sugar into the blood and thus mitigate blood sugar spikes after meals.
Porridge can be wonderfully combined with cinnamon (blood sugar lowering), nuts (healthy fats), and fresh berries (antioxidants).
It also provides long-lasting energy for sports and everyday life.

Diabetes risk: Why take prediabetes seriously?

Prediabetes is more than just a “slightly elevated” blood sugar. Damage to blood vessels, kidneys, and nerves often begins at this stage, even if no symptoms occur yet. Prediabetes is a serious condition and disease that is considered a precursor to type 2 diabetes, also called diabetes mellitus. Untreated prediabetes can lead to serious consequences and risks such as permanent damage to organs and an increased risk of further illnesses. Every year, about one in ten people with prediabetes develops manifest type 2 diabetes. The risk of developing type 2 diabetes from prediabetes is significantly increased.

Type 1 and Type 2: The differences

While type 2 diabetes, also referred to as diabetes mellitus, is caused by lifestyle and insulin resistance, type 1 diabetes is an autoimmune disease in which the pancreas no longer produces insulin. Type 2 diabetes is a serious condition and disease characterized by specific risk factors and physiological changes. The diagnosis of this condition is made based on blood glucose levels, which are measured in mg/dl. Type 1 diabetes cannot be prevented through diet.

Type 2 diabetes, on the other hand, is often preventable and directly linked to overweight, lack of exercise, and diet. Abdominal fat is considered particularly risky here because it releases pro-inflammatory messenger substances that inhibit the effects of insulin. Over time, prediabetes can develop into type 2 diabetes if no countermeasures are taken.

Sugar substitutes and sweeteners: An alternative?

For many people with prediabetes, it is initially difficult to reduce sugar. Natural sugar substitutes can help here:

Stevia, erythritol, and xylitol offer a sweet taste with almost no calories.
They have little effect on blood sugar and are tooth-friendly.
Nevertheless: Sugar substitutes should also be used sparingly. Otherwise, the preference for “sweet” will persist.

Conclusion: Small steps, big impact

Prediabetes affects about one in ten people worldwide and is present in around 20% of adults in Germany. However, many people do not know that they are affected, as prediabetes usually remains undetected for a long time – yet it is a valuable warning signal.

Even small changes in diet, exercise, and stress management can improve blood sugar levels. A tip: Daily walks after meals help regulate blood sugar.
Patience and consistency are important here: Those who stick with it for weeks and months can often significantly lower their HbA1c level and fasting blood sugar. An example: People who consistently avoid sugary drinks often report a noticeable improvement in their levels.
Porridge, collagen, and an overall nutrient-rich diet are delicious companions that can promote well-being.

Final tips for everyday life

Incorporate some exercise every day – 30 minutes of walking is enough.
Tip: A small dietary change can make a big difference. Example: Replace white bread with whole grain bread in the evening and add fresh vegetables – this makes the change easy in everyday life.
Prepare porridge in the morning that keeps you full for a long time and can stabilize blood sugar.
Supplement your diet with high-quality protein, e.g. from fish, eggs, or collagen.
Try to reduce stress through small breaks, yoga, or conscious breathing.
Tip: Schedule regular meal times to avoid cravings.
And: Regular blood sugar checks help you make your successes visible.
