suggestions for class:
why can't you pack anything... lazy ass... do it the night before, get one of those lunchbag cooler to carry around and load it up with things that you probably wont be able to get, or that are too expensive on campus (chicken breasts (2-3), sweet potato (cooked), steamed veggies .. a dish of leftovers from yesterday...) if you eat your breakfast at home and two meals in the evening (one meal, one shake), you should be able to carry 3 meals with you... if you don't have a microwave, you'll have to eat it cold... and you'll get a workout just lugging those things around... put a couple ice packs or even some ice cubes in baggie in it to keep it cool...
my meals away from home, actually even at home are generally eaten out of a single bowl... i take a salad (romaine, red peppers, tomatoes) add chicken breast, add chunks of sweet potato or asparagus or some other veggie and eat away... saves time and dishes... quite easy to do on the road and you can eat meals like this in most lectures (maybe not in labs)
if you buy a hand blender (about $20 US) you can make mrp shakes during your breaks (use the ice cubes from the cooler and some water from a fountain) that'll keep 'em cold while you sip on it... i did this during that training course i was on a couple weeks ago.... worked great!)
there should be healthy type foods you can eat on campus if you need to... use your imagination... get a 6'' sub on whole wheat, extra veggies, no cheese, double meat and only eat half the bread... that's a pretty good meal there... (i like the roast beef, although the processed meat does have a lot of sodium, its better than nothing)
bring a fresh bottle of water and sip at it a bit through the class, about 20 min before its done, chug half and you should be good to go on the break, but sit by the door, just in case...
this whole thing aint easy and it aint fun (and its also a real bitch when you spend most spare seconds you have during the day preparing/eating food), but after awhile it does become a lot easier, like any other routine... but it is a big commitment... this whole lifestyle is...
