In case you haven’t noticed, intermittent fasting is hot right now. Fueled by recent research, it’s being touted by many popular health and fitness magazines, websites and blogs. But is intermittent fasting a good strategy for 50+ adults? We explore that question here.
What is intermittent fasting?
The term intermittent fasting (IF) can apply to any number of very different dietary protocols. Unlike “true” fasting, where no calories are consumed for a sustained period, intermittent fasting often allows some calories even on “fast” days, and those days are interspersed with normal-calorie “feed” days.
Alternate-day fasting (ADF) involves consuming from 0 to 25% of daily calorie needs on alternate days, with normal feeding in between. The 5:2 IF diet is similar, except that 25% of calories are consumed on just two nonconsecutive “fast” days a week, with normal feeding on the other five days.
