I’m 10 stone (61kg approx) and about 5’ 10"  
I cycle to amd from work - 20 minues each way and stay reasonably thin.

I’m gaining weight around my midriff, probably because I’m eating more than I’m burning.  
How many calories do I burn per average day at room temerature sitting at a PC (lunch 5 mins walk)  
I have to do a lot of thinking, does that help?

Lunch is an hour btw, work starts 9:30, ends 7pm.  
Sorry for typos, am hard at work and didn’t proof-read.

About 70-80 cals per hour when you are really lazy and your bum is going numb from being motionless. Much like my sorry job.

Really that low?

How many calories are there in a greasy bowl of sweet n’ sour chicken with noodles?

Probably not as many as you burn over the course of a day, but maybe half that much. If there’s a rich sauce…
