Is intermittent fasting actually healthy?

It can improve weight and metabolic markers for many adults when done safely, but it is not appropriate for everyone.

For most healthy adults it improves metabolic markers and aids weight control without requiring special foods, as long as it's not used to mask disordered eating.

It improves insulin sensitivity, supports weight management, and promotes cellular repair processes in healthy adults.

For most healthy adults, evidence shows it can improve weight control and metabolic health when eating is balanced and the approach fits the person.
