A recent study found that some of the biggest changes during fasting happened after about 72 hours, including shifts linked to metabolism, inflammation, immune function, and brain health.
It's a fascinating reminder that the body is constantly adapting behind the scenes.
That said, longer fasts are not for everyone, and more is not always better. Extended fasting can carry risks and should be approached carefully and intentionally.
The real goal is supporting metabolic flexibility and long-term health, not pushing the body to extremes.
