What I love about this way of eating (I don't want to call it a diet, cause I always feel a 'diet' is something with an end date in sight) is that we can adjust it based on our current goal. Between AFD, 5:2 and 16:8 there's always a way to either lose fast, lose slow or maintain and easy to switch between it. Unlike a conventional diet, where people go back to their old ways of eating when the 'diet' is done, and undo the good they have done.
With fasting, it's easier to 'fix' something with a slight change in eating pattern for a couple of days - before it gets out of hand and you're back where you started.
