How to control your hunger

What are appetite suppressants?

Appetite suppressants are substances that reduce the desire to eat by dampening the feeling of hunger. They can come as medications or dietary supplements and work in different ways. Some affect the central nervous system, particularly the hypothalamus, which plays an important role in appetite regulation. This can lead to a quicker feeling of fullness, resulting in reduced food intake and ultimately weight loss.

There are also products mistakenly called appetite suppressants even though they use other mechanisms. For example, some medications block fat absorption in the intestine and thus contribute to weight loss without directly affecting appetite.

How do appetite suppressants work?

Appetite suppressants influence appetite and satiety through various mechanisms. In many cases they affect the release of neurotransmitters in the brain such as serotonin and noradrenaline. These substances are important for regulating hunger and fullness. When their levels increase, our sense of fullness is enhanced, reducing food intake and supporting long-term weight loss.

Appetite suppressants can also affect the hormones ghrelin and leptin. Ghrelin stimulates appetite, while leptin signals satiety. By lowering ghrelin levels or increasing leptin sensitivity, hunger can be curbed.

In addition, some appetite suppressants slow down the digestive process so that hunger occurs later. This effect can also be achieved through a fibre-rich diet.

Can you lose weight with appetite suppressants?

Yes, appetite suppressants can help with weight loss by curbing hunger and reducing calorie intake. They can be especially helpful for cravings triggered by the desire for quickly available calories such as sugar. These products prolong the feeling of fullness so that less is eaten.

However, the effect of appetite suppressants is often temporary and ends after discontinuation. Long-term use can also cause unwanted effects, especially if reduced food intake leads to a lack of important nutrients. To avoid adverse effects, it is necessary to follow the recommended dosage exactly. Preparations containing bulking agents should be taken with sufficient fluid because they increase stomach volume and thereby enhance the feeling of fullness.

Appetite suppressants can help, but real, long-term weight loss requires a healthy diet and physical activity.

What are the possible side effects of appetite suppressants?

Appetite suppressants can assist with weight loss but are often associated with various side effects. Some products have even been withdrawn from the market for health reasons. The most common side effects include digestive problems such as constipation, nausea, diarrhoea, vomiting or bloating. These symptoms occur because the medications can affect the digestive process.

Headaches are also a common side effect, especially at the start of treatment when the body adjusts to the medicine. Some people may also experience mood changes such as irritability or anxiety, as certain appetite suppressants affect neurotransmitters in the brain. Another risk is possible dependence on appetite suppressants, particularly those with stimulating effects. Abrupt discontinuation can lead to withdrawal symptoms that increase appetite and may result in weight gain.

Palpitations and increased blood pressure are also potential adverse effects, particularly with preparations that promote the release of neurotransmitters like noradrenaline. This can be problematic for people with cardiovascular conditions or related risk. Sleep disturbances such as insomnia or restlessness may occur since some appetite suppressants stimulate the nervous system. Another possible side effect is dry mouth, which if untreated can lead to dental problems.

It should also be noted that taking appetite suppressants can cause interactions with other medications that may strengthen or weaken their effects. They should therefore only be used under medical supervision and after careful consideration of the risks.

Which foods act as appetite suppressants?

Certain foods are particularly effective at suppressing hunger and promoting a feeling of fullness. Nuts are rich in fibre and protein, which leads to long-lasting satiety and helps stabilise blood sugar. Eggs also suppress appetite because their high protein content promotes the release of a hormone that reduces hunger.

Vanilla has been shown to help reduce cravings. The scent of vanilla powder or a vanilla pod may stimulate the release of the feel-good hormone serotonin. Legumes such as beans, lentils and chickpeas are nutrient-rich and low in fat, making them a good choice for a filling diet. They improve blood sugar control and keep you full longer, an effect that chili can further enhance.

Both apples and citrus fruits like oranges contain pectin, a fibre that swells in the stomach and promotes satiety. Pectin binds excess fluid and slows digestion, which can help reduce cravings and stabilise blood sugar. Peppermint acts as an appetite suppressant through its essential oils and ginger, with its spiciness, can reduce cravings for sweet or salty snacks while stimulating metabolism and digestion.

Who are natural appetite suppressants suitable for?

Natural appetite suppressants in the form of minimally processed foods are generally suitable for most people and can be easily integrated into the daily diet. These foods offer health benefits and can be included in family meals without concern.

However, in cases of specific health issues or food intolerances, these foods should be avoided. Synthetic appetite suppressants, on the other hand, can be problematic for certain groups such as pregnant women, children or people with metabolic disorders and may carry health risks in addition to the usual side effects. Special caution is therefore advised when using synthetic products.

What to do about insatiable appetite: practical tips

• Fibre provides long-lasting satiety. Wholegrain products, legumes, vegetables and fruits like apples or carrots fill the stomach and slow digestion.
• Water can dampen the feeling of hunger by filling the stomach. A large glass of water 30 minutes before each meal helps you eat less and curbs hunger.
• Use nuts and seeds as a healthy snack. Almonds, walnuts or chia seeds are natural appetite suppressants. They swell in the stomach, make you feel full and supply valuable nutrients.
• Complement your meals with protein-rich foods. Eat eggs, lean meat or plant protein sources like lentils and tofu to satisfy your appetite.
• Eat slowly and pay attention to your body's signals so you feel full in time. This helps avoid overeating.
• Make sure to eat in a calm and pleasant environment. Avoid distractions such as watching TV, as this can easily lead to unconscious overeating.
• Season your dishes with spicy spices. Capsaicin in chili and cayenne pepper can boost metabolism and suppress appetite.  
• Vanilla flavours can reduce cravings for sweets. Use vanilla in yoghurt or baked goods to decrease your appetite.
• Treat yourself to a piece of dark chocolate; it can reduce the desire for sweets. Choose chocolate with a high cocoa content.
• Stress can trigger emotional eating. Practice techniques such as meditation or breathing exercises to reduce stress and control your eating behaviour.
• Lack of sleep can increase the hunger hormone ghrelin. Ensure you get enough sleep to better control your appetite.
• Plan your meals in advance. Structured meal planning can help avoid unnecessary snacks and cravings.
• Use satiety capsules with specific active ingredients to control your weight. Complement your dietary changes with important vitamins and active substances to optimise the effect.
• Use bitter foods to suppress appetite. Foods like grapefruit or bitter salads such as endive help regulate appetite and support digestion.

Appetite suppressants can help with weight loss, but they should always be used with caution. The key to lasting weight reduction lies in a balanced diet and regular exercise.
