A careful observation of the animal world can help understand the importance of this natural and timeless practice.

Numerous wild animals experience periods of fasting naturally, going through phases of abundance and scarcity of food.

These periods can be influenced by factors such as seasons, food availability, evolutionary adaptations of species, and reproductive needs.

Animals fast when they are injured, ill, during hibernation or torpor, some during mating or nursing periods, during droughts, snowfalls, intense cold, or food shortages. Some birds fast during egg incubation, others immediately after birth.

Fasting during reproductive phases allows animals to concentrate energy resources for reproductive success, thanks to the cleansing that reduces the chance of transferring diseases to offspring.

Some animals hibernate for many months during winter, sustaining themselves only on their body reserves.
