You have probably felt more sluggish than energetic after your lunch break. Your stomach bloats, your eyelids grow heavy, and concentrating on work becomes extremely difficult. It seems that buckwheat with a cutlet is proper food, but somehow it feels like a rock in your stomach. Gastroenterologist and nutritionist Yulia Gorozhankina is sure: the problem is not the amount you eat, but which specific products end up on your plate. She explained what kind of lunch will not cause bloating or drowsiness.

Why «Healthy» Food Makes You Want to Lie Down

According to the expert, the reason lunch leads to unpleasant consequences is short-chain carbohydrates, which are found in many healthy foods. 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 very «problematic» carbohydrates. It is not a strict restriction but a conscious choice of foods that do not cause fermentation.

The doctor notes that many are sure that 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/courgettes in small amounts are acceptable raw, for example as slices. Avocado — a serving of up to 30 grams (about 1/5–1/4 of a fruit) is usually well tolerated,» lists Yulia Gorozhankina.

But white cabbage, broccoli, onions, garlic, asparagus, and celery are better not eaten raw — they often «explode» the stomach. According to the doctor, if you want to eat them at lunch, it is better to choose them heat-treated 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 the plate should be filled with vegetables from the safe list, a quarter with light protein, and the remaining quarter with proper carbohydrates.

«For light protein, fish, turkey, chicken, eggs, or tofu work well. No frying or fatty meat — they slow down the stomach for 5–6 hours. Half 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 and green pepper slices will save the day. Proper carbohydrates are buckwheat, quinoa, brown rice, or sweet potato. They provide energy without sharp spikes in blood sugar and drowsiness,» advises the expert.

But even with a correct set of products, there are several «pitfalls» that can negate all efforts. As the expert notes, to make sure lunch does not «sit like a log» and does not cause drowsiness, it is important to follow several rules.

«Do not wash down your food with carbonated drinks. Season properly: turmeric, fennel, cumin, oregano reduce gas formation, while garlic and onions are provocateurs. Fruits are separate. 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 always activates the digestive tract. Even 5–10 minutes of walking after lunch work wonders. Alcohol at lunch reduces performance and causes drowsiness. I strongly do not recommend it,» warns the doctor.

Yulia also shared a concrete example of an ideal lunch that follows all the rules.

«Turkey fillet on the grill/in the oven 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 doctor notes that such a meal will not cause heaviness, will provide energy to finish the workday, and will not harm your figure.
