Happens to me all the time when traveling. This is why I have fitday loaded on my laptop so I can track macros & calories and adjust when I can eat right.
Short answer is: no starving is never good unless you are on a planned fasting diet.
Here's my answer to traveling (tho I suspect the simple volume of food that you vs what I eat might present some challenges for you):
- I always pack good travel stuff that will cover me in a pinch if I'm stuck in an airport, worse yet, stuck on a plane on delayed take-off, stuck at an airport overnight or just caught starving w/ no immediate options:
-- pouches of tuna
-- protein bars
-- baggie of protein mix+ scoop
-- baggie of oatmeal
-- baggie of almonds or cashews
^^ that stuff is PERFECT to have with you. I also keep a small collection of plastic silverware.
I always try to get a hotel room w/ a mini-fridge and a microwave.
If I can, I'll find a nearby grocery store and get enough stuff to cover most of my meals - if its salad, a tupperware bowl, precooked chicken cuts, some fruit, some water, etc.
I can't stand going into restaurants alone and usually feel sick after eating fast food so I avoid those situations where I can. If you're stuck w/ McDonalds or something, you should still usually be able to find a "clean" meal. I'm more likely to go to a sandwich shop than burger joint if I have a choice, because at least I know what is going into my food. Greasy burgers just make me feel sick and frankly leaves my skin so greasy that I have to go clean my contact lenses.
A perfect example of a foodless situation - I was in Chicago for work, staying in a hotel downtown. Apparently the hotels in Chicago don't have stuff like you'd find at a Marriott Courtyard or something. No fridge, no microwave, not even a coffee maker. (I've been known to make oatmeal in the coffee pot!) Further, because I was downtown, most everything closed, including the Walgreens on the corner, by 6 pm and nothing was open over the weekend except the expensive restaurant next to the hotel. The one breakfast I had in that restaurant, I got my hand slapped when I submitted my travel expenses for spending too much, and it was the cheapest item on the menu. So, to that end, I hit a drug store that was open near my office during the day and picked up some fruit. I made oatmeal + protein mix + cut fruit for breakfast in my room for most of the 6 days I was in Chicago and then picked up some coffee on the way into work. I got lunch at work / wherever. Dinner, several times ended up being a pouch of tuna and more fruit because the choices were spend $$ at the restaurant or nothing, because stuff had already closed. Once I realized how early the places were closing, I also made a point to pick up a good sandwich during the day so I'd have something more than tuna for dinner. But either way, I was covered for all my meals and didn't break the bank, and didn't get caught having the choice of eating shit or not eating.
I'm not saying you need to travel w/ an extra suitcase of food, and I've never really been caught in this situation before because I don't typically go to locations that are in the middle of big cities, but I managed very well. At a min, I carry enough for a couple food emergencies - I always assume the stupid shit is going to happen going to or coming from my destination - caught somewhere in the airport or on a plane. But I can also be comfortable when I do get hungry - even if its a meeting that runs too long or whatever. I'm a miserable bitch on wheels when I get hungry, so I just make damn sure I never get caught w/o something decent to eat.
