Tag: Fasting consistency

According to research from Johns Hopkins neuroscientist Mark Mattson, the human body evolved to go without food for long periods, suggesting an inherent metabolic flexibility. This provides a strong foundation for why many people wonder: can you skip intermittent fasting on weekends?

Research suggests that it takes most people two to four weeks for the body to fully acclimate to a new fasting schedule. During this adjustment period, it is especially crucial to have a plan for *how to stay consistent while fasting* to build a sustainable and long-term healthy habit.

According to Johns Hopkins neuroscientist Mark Mattson, the human body is more adaptable than we often assume, having evolved to endure periods without food. This innate flexibility is key when asking, **does fasting have to be at the same time every day?** The good news is that for many intermittent fasting methods, a rigid daily schedule is not a strict requirement for achieving results.
