Leo Pruimboom ‘Intermittent Living’ is about going ‘back to basics’ – it is about the reintroduction of mild environmentally-based short lasting stress, like cold, heat, hunger, thirst which were once part of an ancient lifestyle.  Dr Leo Pruimboom’s will highlight his research where participants engaged in a 10 day hunter-gather style trip through the Pyrenees where they were exposed to intermittent fasting and drinking, the alternation of cold-heat, and endurance training-high intensity.  He found that coping with ‘ancient mild stress factors’ showed improved metabolic functioning and when combined with forest bathing has also been shown to reduce stress.
