paastoaminen

Paastoaminen is the Finnish term for fasting, the practice of voluntarily abstaining from food and sometimes drink for a period of time. The concept is ancient and appears in many faith traditions, including Christianity, Islam, Buddhism, Hinduism and Judaism, where it serves spiritual, ritualistic, or penitential purposes. In Finnish culture, paasto has also been part of secular health movements and is endorsed by some medical professionals for its potential metabolic benefits.

Typical fasting regimens in Finland range from short daily intervals, such as the 16/8 method (16 hours of fasting, an 8‑hour eating window), to longer periods like 24‑hour or 36‑hour fasts repeated weekly. Intermittent fasting has gained popularity as a weight‑loss strategy, with studies suggesting improvements in insulin sensitivity, lipid profiles, and inflammatory markers. However, research remains limited and outcomes vary among individuals.

Health risks exist, particularly for people with chronic illnesses, pregnant or nursing women, and those on certain medications. Common side effects include headaches, dizziness, fatigue and, in extreme cases, electrolyte imbalance. Medical guidance is advisable before embarking on extended or repeated fasts.

Paastoaminen is also a cultural practice during Finnish holidays such as Lent (Lentusta) or the period between Christmas and New Year, when many people abstain from rich foods to observe a period of reflection. In contemporary Finland, the practice is widely discussed in nutrition circles, media, and wellness communities, reflecting an ongoing dialogue between tradition, science and personal choice.
