                                Studies suggest that longer periods without food, such as 24-, 36-, 48- and 72-hour fasting periods, are not necessarily better for you and can even be dangerous. Knowing exactly how many hours of fasting is unhealthy depends on various factors, including individual health and the presence of underlying conditions. Learning the difference between safe and unhealthy fasting is crucial for anyone considering this practice.
