> the "underlying issue" is fundamentally just being too hungry for how they live

operative phrase in that sentence "how they live". They need to live more active lives. And that's better than a weight loss drug because inactivity causes systemic disease beyond weight gain.

GLP-1 drugs do to hunger what pain meds do to pain, but if you're overweight and your back is aching because you're sedentary the solution isn't a cocktail of drugs, it's to get off your ass, because that lifestyle is going to cause you biomechanical, metabolic and even cognitive issues down the road.

There's disease you can't do anything about and need to treat with medicine, but if you're experiencing symptoms because your lifestyle is abusing your body change your life. There'll come a moment where there's no wonder pill to fix your issues and in that moment you're better of if you know how to actually get control of yourself. Which most import of all is going to give you the confidence that you can change. You don't want to be 50 years old and your only cope in life is praying that a pharma company mutes whatever symptoms plague you.

for many people the underlying issue is serious lack of education when it comes to nutrition.

Not understanding calorie balance, not understanding calorie density of the food they eat.

How many people know 1kg fat = 7700kcal that if they could create deficit of 7700kcal they could potentially lose 1kg bodyfat? Ofc, i know the relationship isn't that simple but for most people this roughly holds true.

If you are eating granolas in breakfast, it may come across as a shock how many calories they pack, go ahead look it up many people believe that's a low calorie health breakfast option.

Many people don't know

1g of carb or protein = 4kcal

1g of fats = 9kcal.

Right so it would seem increased physical exertion would be the answer.

Yeah, humans should have more free time and do enough work or exercise each day to keep their body in shape.
