According to nutritional medicine specialist Dr. Lohse, a homemade porridge made from oats or oat bran, topped with nuts and seeds, is an excellent morning option.

Oats, organic eggs, or whole grain bread? Nutritional medicine specialist Dr. Constanze Lohse explains which breakfast keeps blood sugar as stable as possible — and why porridge can still be a healthy choice.
Eggs instead of oats, vinegar before meals, or going savory at breakfast: countless tips circulate on social media promising to keep blood sugar stable. Oats in particular keep coming up in the debate. Are they really as healthy as their reputation suggests — or are they just
With the claim that "a bowl of oats is like a plate of pasta and oat milk in coffee is like pasta milk," Jessie Inchauspé — better known as the "Glucose Goddess" — ignited a fierce debate on social media. The French biochemist and bestselling author firmly believes breakfast should be as savory, protein-rich, and wholesome as possible. Her own morning meal? Often scrambled eggs made from six organic eggs.
Yet for decades, porridge was considered the gold standard of a healthy start to the day. Is this breakfast classic truly overrated — or is the hype around savory meals largely a misunderstanding? We look at the current research alongside nutritional medicine specialist Dr. Constanze Lohse.
One thing is clear: according to most nutrition experts, a balanced breakfast sets the tone for the rest of the day. But what exactly should that first meal contain if the goal is stable blood sugar and lasting energy? After all, nobody sits down to a plate of pasta with sauce at eight in the morning.
"Nutrition is individual," explains Dr. Constanze Lohse , a specialist in general medicine with a focus on preventive and nutritional medicine. "What works well for one person isn't necessarily the right choice for another."
While some people thrive on a savory breakfast that is low in carbohydrates and high in protein, others find that porridge gives them just as much energy. That said, Dr. Lohse recommends prioritizing protein and healthy fats over carbohydrate-heavy foods, even filling ones.
According to Dr. Lohse, the classic German breakfast of bread rolls with jam or chocolate spread is a "diabetes starter kit." On an empty stomach in particular, this kind of meal causes a rapid spike in blood sugar that then crashes sharply, often leading to cravings and fatigue for the rest of the day.
Compared to bread and spreads, a homemade oat porridge is already a meaningful step up — though it is not the right fit for everyone.

Walking is one of the healthiest forms of exercise, but small everyday habits can reduce its benefits. Here's why pace, posture, footwear, and smartphone use matter more than you might think.

"Oats are carbohydrate bombs," the nutritional medicine specialist acknowledges. Even so, she values oats for their valuable nutrients: "They contain important vitamins, minerals, and above all dietary fiber — including the special fiber beta-glucan, which has blood sugar-lowering and liver-defatting effects."
These nutrients alone set oats clearly apart from pasta or white bread, which offer little in the way of nutritional value and fall squarely into the category of so-called "empty calories."
Dr. Lohse recommends starting the day with something low in carbohydrates: "The first thing you eat in the morning should be as low-carb as possible, to keep insulin release to a minimum." Small salads, radishes, or olives are well suited to this — they ease you into the day gently, without spiking blood sugar.
Meals later in the day can be higher in carbohydrates. "Porridge or oats are perfectly fine in that context," says Dr. Lohse. What matters, however, is making the porridge yourself and combining it with nuts or seeds to get the best nutritional balance.
For anyone who finds a salad at breakfast a little too unconventional, classic egg dishes are a great alternative. "Scrambled eggs, fried eggs, or omelets are all excellent breakfast options," says Dr. Lohse. They pair beautifully with wholesome ingredients such as avocado, tomato, feta, or smoked salmon.
A topped nut-and-seed bread or homemade oat-quark rolls — finished with a boiled egg, cheese, herb quark, or cottage cheese — also make delicious, nutritious morning options that keep you full for hours.
A sweet breakfast can be just as healthy when done right. "A homemade porridge made from oats or oat bran, combined with nuts and seeds, is a great choice," explains the expert. A bowl of quark or yogurt with low-sugar berries such as blueberries works equally well.
One important caveat: "Fruit is not just fruit." "Dried fruits and canned fruit are real sugar traps, and even the classic banana or grapes shouldn't appear on the breakfast table every single day," says Dr. Lohse. For an extra dose of healthy fats and omega-3, she recommends toppings such as flaxseeds, chia seeds, walnuts, or high-quality flaxseed oil.
Although ready-made mueslis in supermarkets are often marketed as wholesome and nutritious, Dr. Lohse says they should generally be "treated just like a plate of pasta." These products tend to be high in sugar and low in meaningful nutrients.
Whether savory or sweet, whether with oats or eggs — what matters most is choosing the right ingredients and preparing your meals yourself. That way, you know exactly what you're eating, can keep things varied, and can truly pay attention to how your body and mind feel throughout the day.
