The real impact of nutrition and physical activity on long-term health

From supplements and weight loss injections to daily routines and long-term behaviour change, the latest episode of amii’s Talking Health & Wellbeing Podcast cuts through the noise to explore what really makes a difference to health and wellbeing. Host Dave Middleton, Executive Chair of amii, was joined by Declan Doyle, Learning and Development Officer for Health@Work, part of the Medicash Group, to discuss the science behind nutrition, common misconceptions, and howindividuals and employers can take a more practical and sustainable approach to wellbeing. With over 20 years’ experience across elite sport, education and corporate wellbeing, Declan shared insights into howpeople often focus too heavily on small details, such as supplements or specific diets, while overlooking the bigger picture. The discussion explored how daily routines, activity levels, sleep patterns and broader lifestyle behaviours have a far greater influence on health outcomes. During the episode, Declan highlighted that many people prioritise the ‘micro’ over the ‘macro’, becoming fixated onindividual supplements or quick fixes, rather than addressing foundational habits. He explained that, while supplements can have a role, they are often the least impactful factor if underlying behaviours around movement, nutrition and recovery are not addressed first. The conversation also examined current trends, including weight-loss medication, with Declan emphasising the importance of supporting individuals to understand and adapt their lifestyle behaviours alongside any clinical intervention to achieve sustainable, long-term results.
