Alkaline Interval Fasting

Healthy weight loss & regeneration

In contrast to diets or fasting, 16:8 Intermittent Fasting - one of the most popular forms of fasting - does not involve a complete change of diet. Instead, within 24 hours, food intake (8 hours) and food deprivation (16 hours) alternate at specific intervals, creating regular and longer breaks from eating. During these fasting breaks, the body switches to repair mode, cell cleansing and regeneration.

Positive health effects

  • More energy and well-being
  • Slowing down of the ageing processes
  • Positive impact on insulin levels, blood lipid and inflammation levels, blood pressure and the immune system
  • Constant metabolic change & prevention of heart problems, diabetes, fatty liver, among others
  • Better weight regulation & avoidance of the yo-yo effect
  • Breaking unhealthy eating habits

If you have any pre-existing conditions, please consult your doctor before starting interval fasting. Interval fasting is not suitable for pregnant or breastfeeding women, individuals with eating disorders or children.

For a great body and a strong immune system

The modern acidic diet, our preference for constant snacking as well as stress and a lack of exercise promote obesity and many lifestyle diseases as well as the weakening of our immune system. Our metabolism and particularly the intestine, our important immune organ, are greatly burdened by processing too many "empty calories" and by the "all-you-can-eat" mentality in modern industrialized countries.

Fasting in the modern era - how does that work?

Fasting is basically in our genes, because our bodies are evolutionarily well adapted to periods of hunger. The 16:8 method is particularly easy to integrate into everyday life. Either breakfast or dinner is omitted, so that you can eat during an 8 hour period and take a break from eating for 16 hours at a stretch. During these fasting breaks, the so-called autophagy process (Greek for "self-cleaning of our cells") begins, which can only take place when insulin production is low. Researchers call it an "all-purpose weapon against age-related diseases", such as diabetes, high blood pressure or dementia.

Intermittent fasting - even better the alkaline way

We spice up the method in an alkaline way. This provides the body with important vital substances and nutrients for strong immune defences. Our recipe ideas also take into account the acid-alkaline balance that is important for our health. Therefore, you can eat your fill with plenty of crunchy vegetables, salads, fruit and gluten-free plants as the mood takes you and enjoy your everyday life.

Think active, too! Regular exercise stimulates the metabolism, promotes detoxification processes, strengthens the muscles and promotes fat burning.


Is constant snacking the order of the day for you? To prepare yourself for the 16:8 method, you can first switch to three meals a day. There should always be a 4-5 hour break between meals.

Intermittent fasting can be done for one day at a time or over several weeks. Try it out whichever way suits you best. The 16:8 fast can also be a good introduction to a therapeutic fast. You can find more information on the Jentschura fasting method on our theme page on "Jentschura's alkaline treatment".
