The purpose of this commentary is to highlight four ways in which the practice of fasting can nourish a rewilding perspective for the fasting person. By freeing the faster for a time from the many social injunctions around food and meals, fasting offers a space for reflection to rethink one’s food practices, and by extension, one’s consumption practices in general. The experience of lack and hunger can also allow a new awareness of the issues of food insecurity in the world. Finally, the fact that contemporary fasting is usually practiced in natural settings reinforces the inclusion of these reflections in an ecological thought and approach, encompassing environmental protection, social justice and better ways for production and consumption. Fasting can thus be seen as a rewilding process, a technique to reach a better being in the world, also resourceful in wild times such as the Covid-19 pandemic.
