12-Hour Fasting – A Key Strategy For A Longer, Healthier Life

You’d be hard pressed to find someone who didn’t know that if you want to be healthy, you should eat primarily healthy food. But what you might not know is, the timing of what you eat matters just as much as what you eat; and there is growing evidence that 12-hour fasting is so protective of health that it can even attenuate the effects of a high-fat diet. What Is 12-Hour Fasting? Also called time-restricted feeding (TRF), 12-hour fasting confines food consumption to a 12-hour window or – put another way – is the practice of, during a 24-hour period, maintaining a 12-hour window where no food is consumed. In practice this may mean that any and all meals/snacks are consumed between 7am and 7pm, with no food being consumed between 7pm and 7am (or 8am-8pm as another example). Some studies actually define time-restricted feeding as an 8-9 hour period, which also shows benefit although not as realistic or easy to achieve as 12 hours. But Why? There has been a lot of research done on many different types and variations of fasting, but I like this particular type of fasting for both what the evidence says, and the logic behind it. There was a time when, in all likelihood, humankind rose with the sun – and days effectively ended with sundown. With no electricity, and only flame for light, food preparation and consumption would have been mostly confined to daylight hours. Nowadays, with access to electricity, we can make meals in the dark well before dawn, and – especially given the long hours some of us keep – make dinner well...
