When the body does not receive food for a few hours, something fascinating happens: insulin levels drop, cells utilize stored energy reserves, and begin to renew themselves.
This metabolic phase stabilizes blood sugar levels, promotes fat burning, and improves insulin sensitivity. Studies show that regular fasting periods activate cell regeneration, reduce inflammation, and support vital repair processes.
Fasting therefore works down to the deepest cellular levels. Through temporary abstinence, the body activates its ability to cleanse and regenerate itself. This process, known as autophagy, was awarded the Nobel Prize in Medicine in 2016 and is considered key to healthy cellular aging and inner balance.
"Autophagy is a fundamental process for degradation and recycling of cellular components. It plays an important role in maintaining cellular homeostasis.” – Yoshinori Ohsumi, Nobel Lecture, 2016
But fasting is more than biochemistry – it is also an attitude. Those who fast consciously sense more clearly when the body needs food and when it does not. This creates a new understanding of mindful nutrition: less automatism, more mindfulness.
What happens in the body during fasting
During fasting, the metabolism becomes more flexible. As insulin secretion drops, the body uses stored fats as an energy source. At the same time, damaged cell structures are broken down – this strengthens cellular health and counteracts inflammation.
“Knowledge of autophagy gives us insight into how the body maintains itself in the face of changing conditions.” – Yoshinori Ohsumi
Blood sugar levels remain more stable, which prevents cravings and keeps energy levels even. These effects occur with almost all forms of fasting – not just intermittent fasting.
Different types of fasting
• Intermittent fasting (e.g., 16:8 or 14:10): Alternating between eating and fasting phases. Supports digestion, blood sugar, and energy balance.
• OMAD (One Meal a Day): One meal per day – ideal for clear structure and mindful eating moments.
• Therapeutic fasting: A multi-day phase with broth or herbal tea – promotes detoxification and mental clarity.
• Alkaline fasting: Focuses on alkaline-forming foods – gentle and balancing.
• Juice or water fasting: Activates deeper cellular processes; should be prepared for mindfully. All forms support the metabolism, regulate insulin levels, and promote regeneration processes in the body.
Conscious nutrition as a key
Fasting and nutrition belong together. After a break from eating, the body is particularly receptive – therefore, what we give it should be nutrient-rich, fresh, and easy to digest. It is traditionally recommended to break a fast with a warm bone broth. It is rich in minerals, collagen, and amino acids, provides the body with energy, and supports the digestive tract in transitioning back to food intake.
Conscious nutrition is not a diet, but an attitude: listening to what the body needs and eating with gratitude instead of out of habit.
Fasting as a ritual – body and mind in harmony
I have been fasting for several years myself and have tried various forms. In my daily life, I usually practice OMAD (One Meal a Day). Shortly before my period, I switch to 16:8 because my body needs more stability then. This year, I tried a 72-hour fast for the first time – not out of ambition, but out of a need for rest and mental clarity. Every experience has shown me: fasting means connecting with one's own rhythm.
Fasting should not be a burden, but a liberation. It is a ritual of letting go – an invitation to feel your body and find the balance between activity and rest.
Conclusion
Fasting is not a diet, but a form of mindfulness. It provides regeneration, inner clarity, and a new awareness of nutrition and health. The focus is not on deprivation, but on what you gain – energy, well-being, and peace.
