To see how your body reacts when you temporarily stop eating, you do not necessarily need sophisticated medical equipment, complex tests or medical staff. In some situations, you can observe your own body’s reactions – as long as you pay attention and remain objective about how you feel.
How to do this assessment
A simple way to observe your body’s reactions is to skip one or two consecutive meals in a day, or to take a break from food of about 24 hours. During this time, you can notice any symptoms that appear when the body is not used to going without food.
What you may notice
a) If, after skipping a single main meal – without eating food or snacks between the previous meal and the skipped one (and the previous meal was moderate) – you get a headache, this may indicate that your body is not used to breaks from eating or that there is a metabolic imbalance.
b) If, after skipping two consecutive meals or after about 24 hours without food, one of the symptoms below appears, your body may be reacting to the release of metabolic substances or to a change in the way it produces energy.
Possible symptoms
- headache
- general discomfort
- dizziness or apathy
- marked weakness
These symptoms do not appear in everyone and are not inevitable. In some cases, they may appear because the body is not used to periods without food, or because it is going through a phase of metabolic adjustment.
What happens in the body
When you stop eating as usual, the body begins to use its internal energy reserves. In this process, various metabolic products may be released from the tissues, and this temporary change can sometimes cause discomfort.
Feeling hungry in the first hours of a break from food is a normal reaction. Cravings or mild irritability may also appear, especially in people who are not used to fasting.
Steps to reduce the load on the body
To support the body’s natural balancing processes and improve your general health, you can take several gradual steps. Water fasting is usually an intermediate stage in a broader process of changing your lifestyle.
1. Awareness and the intention to change
The first step is becoming aware of your lifestyle, your eating habits and the factors that may affect your health, together with a real wish to make beneficial changes.
2. Adjusting your eating habits
You can gradually:
- reduce meat and meat products;
- avoid fried foods and fast food;
- cut down on refined flour products, sugar and very salty foods;
- reduce coffee and alcohol.
3. Supporting the body’s natural processes
Various methods can support the normal functioning of the body, such as:
- hydrotherapy or other procedures that stimulate circulation;
- moderate physical activity, such as walking;
- massage or lymphatic drainage;
- gradual exposure to cold water or lower temperatures.
4. Practising water fasting
After these preparatory steps, you can practise water fasting for short periods, to support metabolic regulation and improve your general well-being.
A new lifestyle
After these stages comes an essential phase: adopting a balanced lifestyle. This means keeping healthy eating habits, balancing activity and rest, and cultivating harmony between body and mind.
