Why You're Always Hungry – And How to Get Your Natural Appetite Control Back

Hunger - more than just an empty stomach

Whether we feel hungry or not is largely determined in the hypothalamus. This is where the control center for our energy balance and thus our hunger regulation is located. A key factor in this process are special brain cells that act as signal stations and constantly evaluate data from the body: How much energy is available? What is the blood sugar level? Which hormones are currently circulating in the blood?

There are two main actors who control this system:

1. Ghrelin - the "hunger hormone": It is produced in the stomach and signals the brain that it is time to eat something. Ghrelin increases when the stomach is empty or when we need a meal.

2. Leptin - the "satiety hormone": This hormone is released by fat cells and signals to the brain "I am full". Sufficient levels of leptin reduce hunger.

This finely tuned system is extremely sensitive. Stress, poor sleep, bad nutrition, or a disrupted gut microbiome can impair regulation and trigger hunger, regardless of our body's actual needs.

Study shows: Lack of sleep increases hunger.

A study¹ at Uppsala University showed that just one night of insufficient sleep can increase activity in brain regions that trigger cravings for high-calorie foods.

Our brain reacts more strongly to visual food cues when sleep deprived - especially high-fat and high-sugar snacks suddenly appear particularly tempting. At the same time, the ghrelin level rises while leptin decreases. The result: we feel constant hunger and less satiety, even though the body actually does not have any additional energy requirement.

A good night's sleep is therefore an important key to preventing cravings.

Appetite is not a coincidence - it's biochemistry.

Modern science clearly shows: Constant hunger is not a sign of "weak willpower" or always a lack of energy, but often an expression of hormonal imbalance or nutrient deficiency. And this imbalance can be restored with the right measures.

How to stabilize your hunger regulation - 5 simple steps:

1. Eat nutrient-rich, unprocessed foods.

A balanced diet rich in vegetables, whole grains, legumes, healthy fats, and sufficient protein stabilizes blood sugar levels and supports the balance of hunger hormones.

Pay attention to having enough:

• Dietary fibers that promote satiety and regulate blood sugar.

• Omega-3 fatty acids, which have anti-inflammatory effects and improve leptin sensitivity.

• Plant-based bitter substances that activate satiety signals via the vagus nerve.

2. Keeping the intestines healthy

A diverse microbiome helps regulate appetite. Prebiotic fibers, fermented foods like yogurt, sauerkraut, or kefir, as well as a colorful plant-based diet promote a healthy gut balance - and thus also appetite regulation.

3. Take breaks for meals.

A regular eating rhythm - for example a 12:12 time window - helps the body to develop natural hunger and satiety rhythms again. Constant snacking keeps the hormones constantly active and disrupts the natural regulation.

4. Optimize micronutrient supply

Certain micronutrients that support metabolic processes also help regulate hunger in a healthy way.

• Zinc contributes to a normal carbohydrate and fatty acid metabolism.

• Chromium contributes to maintaining a normal blood sugar level - stable blood sugar helps reduce cravings.

• Magnesium supports normal energy metabolism and contributes to the normal functioning of the nervous system.

• Vitamin B6, B12, and folate support normal homocysteine metabolism and the function of the nervous system.

• Vitamin B6 supports the regulation of hormone activity.

5. Reduce stress - sleep better

Stress and poor sleep promote the release of ghrelin and lower the satiety hormone leptin. Even small changes such as going to bed earlier or having regular bedtime routines and consciously relaxing (e.g. going for walks, meditation, or breathing exercises) help in maintaining the natural balance of appetite regulation.
