Fasting diets are healthier as well as making us slimmer, according to research by US and Italian scientists.

After finding that mice lived longer when fed a calorie-restricted diet, researchers also discovered that doing the equivalent in humans had a positive impact on health and ageing-related risk factors.

In a study published in the journal Cell Metabolism, researchers discovered that feeding mice a calorie-restricted diet which mimics fasting for just eight days a month promoted regeneration in multiple systems and extended longevity.

Then they monitored the health of a diverse group of nineteen people adhering to a similar five-day low-calorie/low-protein diet once per month for three months.

The diet, meant to mimic fasting, had a positive impact on health and ageing-related risk factors. Larger clinical trials will be needed to support the results.
