If you want to lose weight in a healthy and sustainable way, you will sooner or later come across intermittent fasting as a nutritional concept. Unlike traditional diets, it does without prohibitions and extreme calorie deficits, which is probably one of the reasons why it is so popular.
Here we report on what intermittent fasting actually is and how it works. You will also learn how to get rid of unwanted kilos and which breakfast is particularly suitable. Let's go!
Intermittent fasting – what is it?
Intermittent fasting, also known as intermittent fasting, is a diet that alternates between eating normally and fasting at regular intervals. The concept is becoming increasingly popular, primarily because it is said to have numerous health benefits.
For example, animal models show that type 1 diabetes occurs less frequently in experimental animals when fed according to the method of intermittent fasting compared to a conventional diet. (1)
In addition, the popular diet has a stress- and cancer-reducing effect and is associated with a longer life expectancy. (2)
Now that you know roughly what intermittent fasting is, let's take a closer look at the methods and rules of the diet below. Read in detail what intermittent fasting is.
Losing weight with intermittent fasting – how to do it
Studies show that intermittent fasting is an effective way to get rid of unwanted hip fat. Fasting according to the clock has proven to be particularly effective for people who are overweight. (3)

You can easily find out whether you are considered overweight with the help of our BMI calculator . It is calculated based on gender, height, and weight. If the result exceeds a value of 24.9, one speaks of being overweight according to BMI. However, different levels are distinguished here, which is why there is still no reason to worry if you are slightly overweight.
Now that you know your BMI, you're probably wondering how to lose weight with intermittent fasting. We have written down the most important tips for you:
Tip 1: Find out which variant is right for you
Whether 16:8 or 5:2 is better for you depends on how long you can go without food. Is it very easy for you to give up food for a long time, or is it more difficult for you? After a settling-in period of about 10 days, you will notice whether the chosen variant suits you.
Tip 2: No solid food during a fasting period
In order for your body to access your fat reserves as an energy source during fasting periods, you should completely refrain from solid food during your fasting window. Especially with the 16:8 method, only water, unsweetened tea, and black coffee are allowed.
If you choose a different method, you should consume a maximum of 500 kcal as a woman and a maximum of 600 kcal as a man during a fasting day. These calories are best obtained from light soups or juices.
Tip 3: Eat healthy and balanced
During the meal periods, you can eat normally. Nevertheless, you should keep an eye on your daily calorie requirements so as not to exceed them. Because it is only with a calorie deficit that the kilos drop. How much you can eat to still lose weight, you can easily find out with our calorie calculator .
So that intermittent fasting does not lead to nasty cravings or energy losses, you should also eat as healthy and balanced as possible. A high-protein and high-fiber diet will help you achieve long-term success. Therefore, be sure to include foods such as whole grains, legumes, vegetables, and fruits in your diet.
