secondly obese people cause the nhs so much money
Nope. The NHS delays and misdiagnoses and doctor fobbing off culture costs people their health - including healthy weight - and as a consequence costs so much money.
Costs so much money, due to people being left waiting so long for diagnosis and treatment. So they're in worse health and in need of more (and more expensive) and longer term care, by the time they're actually correctly diagnosed and treated.
This includes the many people who gain weight because of limited mobility (so unable to exercise) due to pain. Or gain weight as a symptom of their health condition. Which then increases their risk of the conditions you mentioned, i.e. diabetes. All because of being left waiting too long for diagnosis and treatment
Like you say the need is to fix the cause, not the symptom. And in many cases (of course, not all cases) the weight loss jab is doing the opposite. It's fixing the symptom, not the cause.
And as you can see from the link I gave in my previous post, chronic stress can cause weight gain. And a major cause of chronic stress is poverty. Linked to that is housing.
Want to save the economy billions? Then address poverty and housing issues - including more council housing asap. (NB. As published in the British Medical Journal, bad or insecure housing harms health - so costs the economy a significant amount of money).
