Summary

This project is feasibility study looking at extreme exercise and possible diet intervention study to counter muscle and weight loss during a 2 person Greenland Ski Traverse in April 2023. By increasing energy intake to above the currently theoretical capacity (2.5 x RMR) the aim is to test a method to find out if there is a maximum to energy intake and whether energy deficit can be minimised; weight loss attenuated, and whether muscle can be preserved. If not, what are the likely adaptive mechanisms and use this to inform future work on dietary interventions
