Tom Clifford interviews Registered Dietitian Diana Davis, R.D. on nutrition pitfalls during COVID-19 lockdown, weight gain, and how to boost the immune system to fight off infection and recover better. We also discuss the effects of alcohol, the best way to supplement for runners, IRON, and some tips on periodizing eating when training increases and decreases. Diana has been a registered dietitian nutritionist since 1983 and has been a Without Limits athlete since 2010. She started running to keep up with her husband, Phillip and their two children. She began as a walker at age 50 and qualified for Boston for the first time in 2019. She is an amazing inspiration on how to start from ground zero and break through limits!
