What are the rules for plane food?

Hi everyone! I'm new here and have a question so hopefully there will be some good tips out there...

I'm leaving Brisbane Australia and flying to London on Friday. It's a long journey (30 hours from LHR to BNE!) and I'm a little worried about managing my food intake while on the plane and at the stopover. Does anybody know where I can find calorie info about Qantas inflight meals? Should I eat fewer calories because I'm moving less? Any other tips for travel-eating would be much appreciated.

Thanks!
