Cheddar my fuse is a bit short today, (I mean shorter than usual) I rolled my eyes at your colleague who is horrified you're considering skipping breakfast. 
Since 5:2 is almost mainstream (at least in people's knowledge, if not experience) the whole starvation mode myth and 'breakfast is the most important meal' has been challenged often enough. Same with "lots of small meals throughout the day". (We're all here because that one works well, right?!)
You could perhaps try 2 plates a few times a week or every other day before 'committing' to see how you feel, then you could also experiment which works better for you, breakfast&lunch or lunch&dinner and how your exercise fits in. And if neither of these seem to work after their trial periods, you still have the option of 3 smaller meals.
I only do intermittent fasting once a week at the moment, would like to build up to more (maybe a version of 5:2 and No-S) but for now I'll focus more on practicing No-S, I'm still a newbie with lots to learn.
Good luck, let us know how you get on!
