When socialising, many people indulge in alcohol, sugar or meat – often in greater quantities than is good for them. A fasting cure is the ideal opportunity to consciously question your eating habits and break established patterns. Some do it for religious reasons, others to lose weight or to boost their wellbeing: there are many different reasons for fasting. A few simple basic tips can make it easier to get started – and both body and mind will reap lasting benefits.

Who should fast – and who shouldn't?

Basically it's okay for healthy adults to fast, but it's always advisable to seek medical advice beforehand. After all, a fasting regimen does put quite a strain on the body. That being said, the following people should avoid fasting:

Preparing for a fast

Good preparation makes it easier to get started and helps minimise side effects:

  • Ease in gradually: A few days before you start, reduce stimulants (alcohol, coffee and nicotine) and switch to light meals.
  • Prepare mentally: Consciously take time for yourself, cut down your commitments and create a calm environment.
  • Set goals: Clearly defined fasting goals (e.g. less sugar, alcohol or meat) boost your motivation and chances of success.

After fasting: the right way to ease back

After the fasting phase it's important to increase the amount of food you eat slowly. Start with easily digestible foods such as:

  • Rusks
  • Honey
  • Rice
  • Lean meat

It's important not to overburden your digestive system. This will help ensure a smooth return to normal.

Why fasting is good for body and mind

Fasting can support your body and mind in many ways. It helps the body to regenerate by easing the strain on metabolic processes and reducing inflammation. Avoiding certain food groups can have a positive effect on certain diseases such as rheumatism, gout and arthritis.

Many people also report more energy, better concentration and a noticeable improvement in body awareness. Fasting can also help you become more aware of your eating habits, break unhealthy patterns and achieve greater wellbeing and inner balance in the long term.

Fasting is much more than a religious ritual – it's an effective tool for promoting health, wellbeing and mindfulness. A combination of good preparation, clear objectives and effective implementation will significantly increase your chances of success. Recent findings also confirm that fasting can have profound positive effects on metabolism, inflammation and mental balance.
