I was hoping anyone with military (or even not) experience can throw out some ideas for what to do. I'm an army reservist and am taking off today for 3 days, than next month for 6 days - all out in the field. We'll be eating rations and/or assorted crap.
What would be good to preserve my muscle mass while doing all this hard work with insufficient calories? I was thinking of bringing lots of protein bars and some glutamine tablets. Suggestions?
