Of course, solving our psychological issues, or finding the time or willpower to exercise, or making the money to buy healthy food or the time to cook it are all different problems. And those problems can be quite complex.

> I think fundamentally the problem of loosing weight is not particularly complex.
My point is that any definition of "fundamental" in this sentence that discards the essential humanity and cultural context of the person losing weight ends up with a "problem" that is in no meaningful, actionable way based in reality.
The fact that it is a real living breathing human who has a life and a day job who is trying to lose weight is essential complexity.
Arguing otherwise is akin to saying that putting an astronaut on the moon is simple: just fire a ballistic missile at it. Oh, what, the astronaut needs oxygen, hydration, and can only handle a certain amount of acceleration before turning into a reddish paste? Well, that's just "artificial" complexity and it's their fault for having a body that is so poorly engineered.
Every normal human understands that "how do I lose weight?" has an implied "while being a normal human with impulses, desires, limited time and willpower, who also has many other goals they are trying to simultaneously satisfy". That problem is fundamentally complex and literally shaming people ("then you have no one to blame for failure but yourself") for being a human in society is counterproductive and harmful.
Practically every overweight or underfinanced person in the world already has a rich fount of shame for those attributes because society keeps telling them it's their fault and that shame is a source of complexity when it comes to solving the problem.
