    dietary supplements

    There are various dietary supplements that give the body a feeling of satiety and reduce the need for calories. They are available in natural form and purely plant-based. However, dietary supplements do not replace a meal. Artichokes and fruit in particular, or foods containing caffeine and L-carnitine, stimulate fat burning and help to lose weight and reduce calories.

    fitness drinks

    If you want to lose weight and reduce your calorie intake, you can skip meals and drink prepared drinks instead. They are precisely matched to the number of calories before consumption and can be individually adapted to the respective body. You can buy them online or stationary. If you enjoy cooking, you can make fitness drinks in the form of smoothies. Due to their liquid form, the food is easier to digest.


    To get rid of calories and burn them, the best way to get there is through exercise. It boosts the metabolism and, through combustion, reduces the calories that you have consumed. Sport also keeps you mentally fit and offers a great balance to everyday life. Nevertheless, caution is required here! A low-calorie diet combined with too much activity can have a negative impact on your own health, because the body needs the energy and strength to get through the day.


    Two to three liters of water a day is considered the ideal daily consumption. Water has zero calories, making it the lowest calorie food of all. If you don't like water, you can drink tea. Without sugar and without milk, it also has zero calories. Fluid saturates the body and fills the stomach. If you find it difficult to drink a lot, you can put a few bottles of water in different places at home, set an alarm clock for water intake, or use apps to remind you of your water consumption.


    All in all, it is easy to eat a balanced and healthy diet with low-calorie foods. Especially in Europe and explicitly Germany, we live in a variety of such foods. In the long run, however, you should refrain from an exclusively low-calorie diet, otherwise the body will lose an important source of energy: calories.

    Before regularly consuming low-calorie food, it is advisable to calculate your personal calorie consumption and the activity and rest times you have brought with you, such as sleeping and sitting, so that you do not end up in a deficit. If you stick to these guidelines, you can eat a balanced and varied diet with low-calorie foods. Gladly also once in combination with rice, potatoes or meat, so that the body is not nourished too one-sidedly.
