What is gluten, and who needs a gluten-free diet?
Gluten is a group of proteins found in wheat, barley and rye; it is what gives bread its elasticity and dough its stickiness. A gluten-free diet concerns three groups. For coeliac patients it is compulsory: the immune system reacts to gluten and the small intestine is damaged; even the smallest amount causes problems. People with gluten sensitivity do not have coeliac disease, but gluten causes symptoms such as bloating, abdominal pain and tiredness; they feel better when they eat gluten-free. The third group is people who choose to eat gluten-free without any diagnosis; for this group a gluten-free diet does not cause weight loss by itself, but it can bring indirect benefit by reducing processed food. If coeliac disease is suspected, you need to see a doctor and be tested before starting a gluten-free diet; once the diet has started, test results lose their reliability.
What is eaten and what is not?
- Naturally gluten-free: Rice, corn, buckwheat, quinoa, millet, potatoes, legumes, all vegetables and fruit, meat, chicken, fish, eggs, dairy, nuts, seeds, olive oil.
- Needs attention: Oats (can be contaminated with wheat in production; must be labelled "gluten-free"), ready sauces, stock cubes, processed meat, ready soups, some spice mixes and chocolates; reading labels is essential.
- Not eaten: Wheat, barley, rye and bread, pasta, bulgur, semolina, couscous and pastries made from them, beer, products containing malt.
Because bread and bulgur are central in many cuisines, gluten-free eating looks difficult at first glance; yet rice pilaf, cornmeal recipes, buckwheat, potatoes, legume dishes, vegetables in olive oil, grilled dishes and vegetable fritters fill the list more than enough.
Can you lose weight on a gluten-free diet?
Being gluten-free does not make a food low in calories; gluten-free cakes, biscuits and breads often contain more sugar and fat than their normal equivalents. For weight management, a gluten-free diet is followed together with the rules of a balanced diet: the calorie target is calculated from personal need, protein is present at every meal, vegetables take the largest share and gluten-free grains are used in measured amounts. A programme built this way both eases digestion and brings healthy weight loss.
A sample day
- Breakfast: A two-egg vegetable omelette, white cheese, tomato and cucumber, olives, 1 slice of gluten-free or corn bread.
- Snack: 1 bowl of yoghurt and a handful of walnuts.
- Lunch: Lentil soup (without flour), grilled chicken, 3 tablespoons of rice pilaf, salad.
- Snack: 1 piece of fruit and 5 almonds.
- Dinner: Baked fish or meatballs (with cornmeal instead of breadcrumbs), vegetables in olive oil, buckwheat salad.
- Evening: 1 glass of ayran or herbal tea.
Points to watch when eating gluten-free
- Read labels. Gluten is found in the most unexpected products: soy sauce, ready soup, processed meat, some ice creams.
- Cross-contamination. For coeliac patients, the same toaster, the same frying oil or even the same chopping board can be a problem.
- Fibre and B vitamins. When whole wheat goes, fibre and B vitamin intake can fall; legumes, vegetables, quinoa and buckwheat cover this.
- Do not rely on packaged gluten-free products. Packaged gluten-free snacks are often loaded with sugar and fat; naturally gluten-free foods are the basis.
The 5 most common mistakes
- Starting the diet without being tested. If coeliac disease is suspected, test first; once the diet starts, results mislead.
- Living on packaged gluten-free products. Loaded with sugar and fat; they cause weight gain. Naturally gluten-free foods are the basis.
- Not reading labels. Soy sauce, stock cubes, ready soup and processed meat are hidden sources of gluten.
- Neglecting fibre. Fibre falls when whole wheat goes; it should be replaced with legumes, vegetables and buckwheat.
- Ignoring cross-contamination. For coeliac patients even a shared toaster or frying oil is a risk.
How is the gluten-free programme applied on Diet Prof?
After the free analysis you state at the start that you eat gluten-free (because of coeliac disease, sensitivity or by choice), or send it from Dietitian Support. Your list is built without any dish containing wheat, barley or rye; based on rice, buckwheat, corn, potatoes and legumes, and this preference is kept in later periods too. The ingredients of every recipe are written clearly on the meal card; your shopping list is generated with gluten-free ingredients. With Change Meal you switch only between gluten-free options. If you have a coeliac diagnosis, be sure to report it; the dietitian team removes recipes with a cross-contamination risk from your list. Details are on the How Does Diet Prof Work? page.
Frequently asked questions
I am not coeliac. Is eating gluten-free good for me?
If you have no symptoms, it is not necessary. The benefit usually comes not from gluten itself but from reducing pastries and processed food; the same benefit is obtained with a balanced diet.
Is bulgur gluten-free?
No; bulgur is made from wheat and contains gluten. Rice, buckwheat and quinoa are used instead.
Can I eat oats?
Only oats labelled "gluten-free"; ordinary oats may have been contaminated with wheat during production. Coeliac patients should discuss this with their doctor.
