When we look back at our evolutionary history, fasting was a natural part of life.
As hunter-gatherers, there were periods when food was scarce, and our bodies adapted to these circumstances by slowing down metabolism and increasing cortisol levels to release amino acids from muscle stores.
While this was a survival mechanism during times of famine, it’s important to recognize that these adaptations were designed for a different environment one where food scarcity was a part of daily life.
In today’s world, deliberately mimicking those survival conditions by fasting for extended periods may not always be the best approach, especially when we have access to food and proper nutrition that our bodies need to heal effectively.
