You have probably felt more sluggish than energetic after a lunch break. Your stomach bloats, your eyelids grow heavy, and focusing on work becomes extremely difficult. Buckwheat with a cutlet seems like proper food, but somehow it turns into a stone in the stomach. Gastroenterologist and nutritionist Yulia Gorozhankina is certain: it is not about the amount eaten, but about which specific products end up on the plate. She explains what kind of lunch will lead to neither bloating nor drowsiness.

Avoid sweetened drinks at lunchtime to reduce bloating and drowsiness.

Why you feel like lying down after «healthy» food
According to the expert, the reason lunch leads to unpleasant consequences lies in short-chain carbohydrates, which are found in many healthy products. They are poorly absorbed in the small intestine and become food for bacteria in the large intestine, causing vigorous gas formation.
Yulia suggests paying attention to the low-FODMAP approach — a diet that excludes those same «problematic» carbohydrates. This is not a strict restriction, but a conscious choice of products that do not cause fermentation.
The doctor notes that many people believe any raw vegetables do not cause bloating, but in reality it all depends on the specific type.
«Here are which fresh vegetables and greens almost never cause discomfort (low-FODMAP champions): carrots, cucumbers, tomatoes, bell peppers (especially green), iceberg lettuce, arugula, spinach (baby leaves), leaf lettuce. Zucchini in small amounts are also acceptable raw, for example as slices. Avocado — a portion up to 30 grams (about 1/5–1/4 of the fruit) is usually tolerated perfectly,» lists Yulia Gorozhankina.
But white cabbage, broccoli, onion, garlic, asparagus, and celery are best not eaten raw — they often «explode» the stomach. According to the medic, if you want to eat them at lunch, it is better to choose them cooked or replace them altogether.
The ideal lunch: what it looks like
The simplest and most effective way to assemble a lunch that will not put you to sleep or cause bloating is to use the 25-50-25 rule. According to this principle, half of the plate should be vegetables from the safe list, a quarter — light protein, and the remaining part — proper carbohydrates.
«For light protein, fish, turkey, chicken, eggs, and tofu are suitable. No fried food or fatty meat — they slow down the stomach for 5–6 hours. Half of the plate is vegetables. You can take baked zucchini and asparagus, or a mix of fresh cucumbers, tomatoes, and arugula with olive oil. If you want crunch — carrot sticks and green pepper slices will save the day. Proper carbohydrates are buckwheat, quinoa, brown rice, sweet potato. They provide energy without sharp spikes in sugar and drowsiness,» advises the expert.
But even with the right set of products, there are several «pitfalls» that can nullify all efforts. As the expert notes, to prevent the lunch from «sitting like a stone» and causing drowsiness, it is important to follow several rules.
«Do not wash down your food with fizzy drinks. Season correctly: turmeric, fennel, cumin, oregano reduce gas formation, while garlic and onion are provocateurs. Fruits — separately. An apple, pear, or watermelon eaten right after a cutlet guarantee fermentation. Berries or citrus fruits are better left for a snack 1.5–2 hours later. Movement is always an activator of the gastrointestinal tract. Even 5–10 minutes of walking after lunch works wonders. Alcohol at lunch reduces performance and causes drowsiness. I strongly advise against it,» warns the doctor.
Yulia also shared a specific example of an ideal lunch that meets all the rules.
«Grilled or baked turkey fillet with paprika and oregano, a salad of fresh cucumbers, tomatoes, and arugula (dressing: lemon juice + olive oil). Side dish: quinoa with turmeric and a drop of ghee. Afterwards: mint tea or water with lemon,» suggests the specialist.
The medic notes that such a meal will not cause heaviness, will provide energy to finish the workday, and will not harm the figure.
