I tried skipping breakfast (cos I'm often feeling very nauseous) but need something to stop the morning glucose dump, so now I'll usually have a yoghurt and some berries or nuts, or at this time of year oatmeal. I occasionally have a full grill up (I rarely fry stuff nowadays), I do this rarely because good quality bangers and stuff expensive. If I have breakfast I find I eat less the rest of the day, but if I start out hungry, I stay hungry it seems. I'm lucky in a way that I can eat what and when I want to as I cover it with insulin.
If you're T2 and not on insulin, eating at regular times (and incidentally taking your meds at regular intervals) can help stabilise numbers, but everyone knows life gets in the way so this is not always possible. It's worth making the effort though, as I'm told it really can help.
