Lastly, consider carnivore or alternate day fasting. You can get there, if you want to.
While I'm sure you mean well, but "just try harder for longer" isn't new advice and certainly not good advice. All evidence we have is that you are entirely unlikely to stick it through. Dopamine is the most powerful mechanism in our existence.
My point is that "there" is a miserable place, and so I don't stay "there".
BTW, I have (controlled) hypertension, (controlled) high cholesterol, high triglycerides, low HDLs, and a large beer belly gut (just like my dad, but unlike my brother)... but I have hba1c on the low end and high insulin sensitivity. Doctors used to insist I was on the path to diabetes (25 years ago), but now they are mystified. I chalk it up in part to fasting and drinking a lot of coffee, and my revulsion towards sweet tasting food (I love fat, starch and salt... but not sweet).
So I have a lot of doubt about insulin-related explanations given my well controlled blood sugar. But I still think hyper low-carb might work.
As an aside, long-distance running works to a limited extent. I drop weight without trying and my hunger does not increase. Other forms of burning calories, however (e.g. bicycling), have not had the same effect.
Alternate day eating etc.

Your view is contradicted by the scientific evidence.
