With regards to the thread question, to be honest I'm probably similar. At the weekend I rarely eat much at all. I'll have some toast and an egg for breakfast, don't really do dinner (or lunch as some call it) and then the only real eating event is the evening tea. Normally at the weekend we're either out walking or I'm working on something -- eating just becomes something done out of habit when I don't really feel I need it. That's why I cannot stand driving to eateries, having a huge two or three course meal and driving home. Don't feel I've earnt it at all...
I found I ate a lot more when I was furloughed in 2020, when I absolutely didn't 'need' it. I imagine those stuck at home economically inactive may have poorer eating habits because they may not have the type of routine brought about through a job. It sounds harsh but - I think - a reasonable assumption.
I was actually taught at school by my biology teacher to eat five small meals a day. Little and more often was the rule she taught us.
