We can play the word game of hunger too. Any claim of hunger that is not followed by eating when given the opportunity is suspect.
When a child complains of being hungry and pointing at the donuts, we offer them an apple and they storm off in a huff, we say "ha, you weren't really hungry". We reject the claim of hunger and instead suspect a desire for sugary stimulation.
Hunger is not a pure mental state but a case where physical sensations are labelled as hunger and we should often doubt that labelling. If you are on a diet there are common maxims like "are you hungry or just bored?" with advice to seek distraction because a momentary physical sensation will fade. We confuse many physical sensations for what we might want to strictly define as hunger especially when eating makes those sensations cease e.g. dyspepsia, low-mood, boredom etc. Initial assumptions of hunger can be relabelled just like the "I am excited not anxious" trick before public speaking.
The physical sensations driving the type of hunger from habitual anticipation of food are caused by observable changes in the body as it prepares itself (hormonal changes / stomach acid etc.). That gives some empirical baseline beyond qualia. So for this person on the sofa, too lazy to go eat, we should be suspicious of their labelling but can look at what their body is doing.
It's also notable that if you do any long term fasting (weeks) you find people talk about hitting "real hunger" and it's startling different experience from everyday hunger. I expect there are related physical changes but it's quite a different mental sensation - it's almost like fear - the feeling of an alarm cord being pulled and an "oh shit, I have to eat now".
