A new
discovery suggests it may also aid with weight loss, possibly by making the more
efficient at switching from using food for energy to using stored fat.
In
February 2026, a review of existing research concluded that intermittent fasting –
such as the 5:2 diet, where you eat as normal on five days a week
and restrict calories on the other two – is probably no more effective for
weight loss than doing nothing at all. But fasting can also involve eating no,
or very little, food for a single, continuous stretch of time, which is
sometimes done for religious reasons.
