Though we understand exercise to be good for our wellbeing, there is a lot still to learn about the complex and varied ways physical activity drives positive health outcomes in humans.

Scientists digging into the molecular details of this relationship have made a significant discovery, pinpointing a modified amino acid that spikes in the blood following intense exercise, and travels to the brain to suppress hunger and in turn drive weight loss.

“We’re all generally aware that exercise is beneficial,” said Jonathan Long, an assistant professor of pathology at Stanford University, who led the research. “It’s good for body weight and glucose control. But we wanted to take a look at that concept in more detail – we wanted to see if we could dissect exercise in terms of molecules and pathways.”

To this end, Long and fellow study authors from University of California, Davis and Baylor College of Medicine turned to a technique called metabolomics. This meant leveraging mass spectrometry to track the concentration of different molecules in tissue and blood samples, and how exercise caused levels of certain ones to rise and fall.

Initially, this was put to use on mice who were made to carry out a short session on a treadmill, with the scientists able to pinpoint a large spike in a certain molecule after the workout. Analysis of blood from racehorses came next, with the team again seeing a spike in the same mysterious molecule after their exercise.

Everyone wants to live longer.

And we’re often told that the key to doing this is making healthier lifestyle choices, such as exercising, avoiding smoking, and not drinking too much alcohol. Studies have also shown that diet can increase lifespan.

A new study has found that eating healthier could extend lifespan by six to seven years in middle-aged age adults, and in young adults, could increase lifespan by about ten years.

The researchers brought together data from many studies that looked at diet and longevity, alongside data from the Global Burden of Disease study, which provides a summary of population health from many countries.
