Intermittent fasting can help improve immunity, potentiate detoxification, and also improve mental alertness and agility. This type of fasting consists of not eating solid foods between 16 and 32 hours a few times a week on a scheduled basis, returning to a usual diet, preferably based on foods low in sugar and fat.
To get the benefits, the most common strategy to start this fast is to go without food for 14 or 16 hours, just drinking liquids such as water, tea and coffee without sugar, but this lifestyle is only advisable for healthy people and, thus, the consent and support of a doctor, nurse or health professional who is aware of this type of fast is necessary to ensure that it is well done and works well for health.
Main types of intermittent fasting
There are different ways of being able to do this kind of deprivation, although in all of them a period of food restriction and a period in which one can eat is realized. The main ways are:
- Fasting of 16h, consisting of staying between 14 and 16 hours without eating, including the sleep period, and eating in the remaining 8 hours of the day. For example, dinner at 9 at night, and return to eat at 1 pm the next day.
- 24-hour fasting is done for an entire day, for 2 or 3 times a week.
- 36-hour fast, consisting of staying 1 full day and more half of the other day without eating. For example, eat at 9 at night, spend the next day without eating, and go back to eating at 9 in the morning the other day. This type should be done by people more accustomed to getting fasted, and under medical guidance.
- Eat 5 days and restrict 2 days, which means eating for 5 days of the week normally, and in 2 days reduce the amount of calories to about 500.
In the fasting period, water, teas and coffee are released, without the addition of sugar or sweeteners. It is common in the early days to feel very hungry and, in the days that follow, to get used to it. If the hunger is very strong, you should eat some light food, because no one should suffer or go wrong by adopting this habit.
