Intermittent Fasting: Is Eating in an 8 Hour Window Actually Beneficial?

You've heard of the potential health benefits of intermittent fasting: advocates of the 5:2 diet – in which you have five days of eating normally and two days on 500-600 calories – have made some pretty bold claims about it's possible outcomes, including enhanced cognitive function and protection against conditions such as dementia and Alzheimer’s disease.

(To note: there is not scientific consensus on this – and the jury is very much still out.)

But the latest incarnation of this idea is somewhat simpler.

The 16:8 entails consuming all of your food in an eight hour window. If you are looking to lose weight in a safe, sustainable way, then it's been suggested that this could be one way of doing it.

To see how compatible it is with real life, one writer tried intermittent fasting out.

Here's the results.

Intermittent fasting results: I tried eating in an 8 hour window

It’s 9pm and my boyfriend is sitting opposite me devouring dinner. I, on the other hand, am clutching a glass of water, my last meal a distant memory at 5.45pm and my next not till 10am tomorrow.

I’m on week four of trying 16:8 intermittent fasting. I can eat anything and everything, as long as I consume it all within one eight-hour window per day, then give my body 16 hours off food.
