The term 'green exercise' was coined by researchers at the University of Essex to describe physical activity in natural environments. A decade of research has since confirmed what many people intuitively sense: exercise outdoors, particularly in green or blue spaces, has measurable psychological benefits beyond those of equivalent indoor exercise.
Two main theories: Attention Restoration Theory suggests that nature provides 'effortless attention' that rests the directed attention systems required for focused work, reducing mental fatigue. Stress Recovery Theory suggests that natural environments trigger an evolved relaxation response, as our nervous systems are calibrated for natural settings as 'safe'.
Parks, urban green spaces, waterways, coastal paths, and even tree-lined streets have demonstrable green exercise effects. Access to wilderness is ideal but not required. Studies show benefits from urban parks. Even a view of trees from a window during indoor exercise produces some enhancement of mood and concentration.
Getting 100g+ of protein daily on a reduced appetite is hard. Strategic timing makes it more achievable — and more effective for muscle preservation.
Medication helps with appetite. But the mental skills for sustainable weight management — resilience, flexibility, self-compassion — must be built intentionally.
