In this 2-phase randomized controlled study, we examined whether consuming a higher-protein (HP) diet would attenuate fat-free mass (FFM) loss during energy deficit (ED) at high altitude (HA) in 17 healthy males (mean ± sd: 23 ± 6 yr; 82 ± 14 kg). During phase 1 at sea level (SL, 55 m), participants consumed a eucaloric diet providing standard prot...

... High-protein diets have been used to improve skeletal muscle anabolism during eucaloric feeding and preserve lean mass during hypocaloric feeding (Morales et al., 2017;Pasiakos et al., 2015). However, these diets lack efficacy during the severe energy deficits often experienced by military personnel (Margolis et al., 2014(Margolis et al., , 2016Berryman et al., 2018), and alternative solutions are needed. Testosterone administration is one potential solution as the hormone acts in a dose-dependent fashion to increase anabolic balance, lean muscle mass, and muscular strength in healthy men (Bhasin et al., 1996(Bhasin et al., , 2001. ...
