Researchers from the Baylor College of Medicine, publishing their findings in the journal Nature, have found a molecule produced by the body during exercise that can reduce appetite and obesity.
The research team analysed blood samples from mice who had run on a treadmill and found a modified amino acid called Lac-Phe was produced from lactate and phenylalanine. When obese mice on a high-fat diet were then given Lac-Phe, it reduced food intake by approximately 50 per cent over 12 hours.
If we can harness this molecule and put it in pill form, could we at some point get all the benefits of exercise from simply taking a tablet? This is an exciting idea, as it may offer a way to improve the health of people who struggle to exercise due to various conditions or illnesses.
As this study demonstrates, in our world there is a lot of focus on the physical health benefits of exercise, but not so much attention on the mental and emotional benefits an active lifestyle can offer. Exercise has an impact on our self-esteem and confidence, our cognition, our sense of purpose, our ability for connection, and our sense of achievement in reaching bespoke and personalised goals.
