NUMBER ONE on my flying rules is DRINK A LOT OF WATER. Ask for an extra bottle. Drink some when you've landed and are waiting for a connector. Drink water. The flights can be dehydrating and sometimes we have to wait for food when we're hungry. Water water water.
I fly this way at least 2 or more times a year. I try to eat a good healthy meal before I get to the airport because on the plane as the food can contain a lot of sodium.
Like Farie says above DRINK A LOT of WATER and if you are prone to leg swelling try to find some support panty hose or compression socks. They will help with that problem. I have a big issue with that happening when I fly from Seoul to NYC.
As far as eating on the plane....I see you ordered a kosher meal. The special meals although it is still airplane food usually come a out a little more well prepared. I would do as the others say here and choose to bring some healthy snacks.
I am not sure if you are in economy or business but when I fly business the airline I use sets up a snack buffet with some healthy choices. This helps a lot as well.
You may be sleeping for some of it or maybe not but bring some things to entertain yourself as well.
I hardly sleep unless I am utterly exhausted. I just can't do it unless I pass out. So I bring a book that is a pretty quick read and listen to the music stations...(I am also not much for watching the movies on the flights.)
You will not be in too bad a way as far as food chocies and staying on plan and like Nelie says you will probably have a lay over in an airport where something to eat will be available although not all terminals have a lot of choice. Narita in Japan for the airline I fly is VERY limited in choices. Just think portion and look for what you can as far as healthy goes.
