Feast or Fast?

Feast or Fast?

On Thursdays so-and-so only eats walnuts, and what’s-his-name hasn’t eaten anything but goji berries all day. The 5:2 diet has come in with such a bang that some of us feel we’re coaxing death by sticking to the 7:0. Fasting, everyone’s at it – even microscopic worms. A new study has found that when the tiny nematode worm C. elegans (pictured with red-coloured sex cells and green-labelled muscle cells) is deprived of food, its cells and organs enter an ageless state of arrested development. When food becomes plentiful again, the worm develops normally, but lives twice as long as its free-feeding counterparts. Starvation doubles its two-week lifespan. Food deprivation can also extend the lifespan of rats, mice, flies, spiders, fish and monkeys by 30 to 200 per cent. This study has implications not only for ageing, but also for explaining how cancer cells lie dormant for years before reawakening.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
