Study identifies multi-organ response to seven days without food. New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.

The study, published in Nature Metabolism, advances our understanding of what’s happening across the body after prolonged periods without food.

By identifying the potential health benefits from fasting and their underlying molecular basis, researchers from Queen Mary University of London’s Precision Healthcare University Research Institute (PHURI) and the Norwegian School of S...

Fasting triggers autophagy in our body. The body switches on the waste disposal system in the cells and gains new energy. Researchers at the Max Planck Institute for Metabolism Research in Cologne have now shown in mice that the brain plays a decisive role in this process.

Even after a short period of fasting, the brain triggers the release of the hormone corticosterone and thus initiates autophagy in the liver...

Existing drugs may offer effective treatment. Prevailing theories posit plaques in the brain cause Alzheimer’s disease. New UC Riverside research points to cells’ slowing ability to clean themselves as the likely cause of unhealthy brain buildup.

Along with signs of dementia, doctors make a definitive Alzheimer’s diagnosis if they find a combination of two things in the brain: amyloid plaques and neurofibrillary tangles. The plaques are a buildup of amyloid peptides, and the tangles are mostly made of a protein called tau.

“Roughly 20% of people have the plaques, but no signs of dementia,” said UCR Chemistry Professor Ryan Julian. “This makes it seem as though the plaques themselves are not the cause.”

For this reason, Julian and his colleagues investigated understudied aspec...

Fasting may help people lose weight, but new research suggests going without food may also boost human metabolic activity, generate antioxidants, and help reverse some effects of aging. Scientists at the Okinawa Institute of Science and Technology Graduate University (OIST) and Kyoto University identified 30 previously-unreported substances whose quantity increases during fasting and indicate a variety of health benefits.

“We have been researching aging and metabolism for many years and decided to search for unknown health effects in human ...
