Fasting – more than a diet
Celebrities, influencers and sportspeople alike swear by fasting. Fasting for a specific period of time has an incredible effect on the body. But if you want to give it a go, you have to be prepared.
It may sound like a short-lived trend, but fasting has been around for centuries. So how does fasting work? One of the best-known methods is traditional therapeutic fasting. This is similar to a starvation diet (see infobox). With intermittent fasting, you abstain from solid food only for a certain period of time. The 16:8 method, for example, involves fasting for 16 hours and only eating within an eight-hour window each day. The 5:2 diet is also popular, where you eat normally for five days and reduce your calorie intake to a quarter of your daily needs for two.
Fasting improves cell function and strengthens the immune system.
Over the years, many researchers have investigated whether fasting is beneficial. It has been proven that voluntary fasting shocks the body in a positive way and triggers a series of biochemical reactions.
Current research results show that intermittent fasting, for example, could be an effective way to prevent type 2 diabetes. Studies with mice have also shown that alternate day fast, i.e. Fast one day and eating the next, can prolong the animals’ lives. What’s more, intermittent fasting trained the mice’s metabolism so effectively that even latent type 2 diabetes could be avoided.
The key to fasting: preparation and follow-up
To get fasting off to a good start, it’s a good idea to avoid heavy and fatty food a few days before you’re due to begin and to eat mainly light foods. You musn’t drink alcohol or smoke during this phase. Emptying your bowels reduces the feeling of hunger. It’s always a good idea to discuss fasting with your doctor, particularly if you have a pre-existing condition for which fasting may be unsuitable.
Once you’ve finished fasting, your body has to slowly adapt to eating normally again. You should eat light, low-fat foods, such as vegetables and fruit. However, you should also stay away from sugar, fats, alcohol and caffeine during this phase, because your body needs time to adjust to solid food again.
A typical day during a therapeutic fast
With therapeutic fasting, your daily nutrient requirements are covered only by fluids containing minerals.
Example daily menu:
- Morning: herbal tea
- Lunch: vegetable or rice broth and water
- Afternoon: herbal tea and water
