Fasting is becoming more popular—not just for detoxification, but also as a way to shed extra pounds. One of the favorites is the 7-day fast. But how much weight can you really lose in a week? And what exactly happens in your body during this time? Let me take you on a gentle journey through a week without solid food—honest, compassionate, and with a focus on the bigger picture.
Why do so many people fast in the first place?
Fasting takes many forms: some do it with medical guidance, others for spiritual reasons, or simply because they want to give their bodies a break. The classic approach is therapeutic fasting according to Buchinger, where you avoid solid food for a week and only drink fluids—like vegetable broth, diluted juices, water, and herbal teas.
A common side effect—and sometimes the main motivation—is weight loss. But is it really that simple?
7 days of fasting = 3–5 kilos less?
Most people actually lose between 3 and 5 kilograms during a week of fasting—sometimes even more. The reason is that your body doesn't just tap into fat reserves; it also loses water and glycogen stores at first, which quickly shows up on the scale.
It's important to know:
- The initial weight loss is often not just fat reduction.
- If you go back to your usual eating habits afterwards, you'll quickly regain the weight.
- The effect is lasting only if you use fasting as a starting point for a more mindful lifestyle.
What happens in your body during fasting?
When you fast, your body switches from burning glucose to burning fat after about 24–48 hours—a process called ketosis. This leads to:
- Reduction of body fat
- Lower blood sugar levels
- Relief for your liver and gut
- Activation of your body’s self-cleaning processes (autophagy)
Many people also notice sharper perception, a deeper sense of inner calm, and better sleep—weight loss often feels like just a side effect.
Experiences: What do others say about 7-day fasting?
Many who fast find the first half of the week challenging—headaches, tiredness, or irritability are common. But by day 3 at the latest, most people experience a sense of lightness and clarity. Some say they’ve never slept better or felt so in tune with their bodies.
Weight loss is appreciated, but it’s often seen as less important than the boost in energy and well-being.
Is fasting a good way to lose weight?
Fasting can be a great kick-off—a kind of reset. But just going without food for 7 days won’t bring lasting change. If you eat more mindfully, move more, and treat yourself with care afterwards, you can benefit from fasting in the long run—both physically and emotionally.
But be careful:
- Fasting is not suitable for everyone – for example, if you are underweight, have eating disorders, are pregnant, or have chronic illnesses.
- Medical supervision is especially recommended if it's your first time.
- After fasting, the rebuilding phase is crucial – take it slowly and gently.
Conclusion:
Yes, you will lose weight during a 7-day fast – often even several kilos. But the real benefit goes deeper: it's the sense of clarity, lightness, and a renewed connection with your own body. Fasting can be so much more than just a diet – it can be a fresh start 🌿
