1, lifelong dependency that's just another form of addiction and everything that comes with it.
WLI are not addictive. If you are meaning a psychological reliance, rather than a true addiction, then you are ignoring the fact that people can choose to remain on Mounjaro for maintenance, it is approved for that. So it is no more an "addiction" than using any other long term medication.
2, you need to be morbidly obese to get it on the NHS, leading to people not trying to lose weight the conventional way.
Huh? The two parts of this sentence don't seem to be connected to each other. Are you maybe suggesting that there a lots of people who don't try to lose weight in order to become morbidly obese so they can access medication on the NHS?? If so, that seems unlikely. To access Mounjaro, you need to also have 4 out of 5 specific weight related health conditions, so you'd need to "hope" you also acquired those as well as being morbidly obese. Would anyone really do that?? As for Wegovy, that's only available via specialised weight loss services, in some areas , instead of being offered bariatric surgery. You need to be on Tier 3, which means waiting for a referral sometimes for 18 plus months, and then working through the process which includes things like coaching and dietician support.
3, self funding I really wonder why? Is there is something we are not told and healthcare providers do not want the responsibility? Or is it simply costs & the morality of lining big pharma companies pockets.
WLI are available privately because they are approved by the MHRA, that's all. They are available also on the NHS, but that is currently rationed as described above and that decision to ration was due to cost and ability to manage numbers practically. The rollout plan is over 12 years in order to handle this.
4, secondary impact on the food industry- they still get away with selling junk as healthy while decent fruit & veg costs an absolute fortune!
What has this to do with WLI? Nothing stopping anyone for campaigning about junk food and cost of fresh food. People taking WLI are usually all eating healthy food as a result, not just less junk food.
5, it's new and we have no idea about the long term health implications.
There are many new medications. Each one goes through clinical trials, lengthy ones, that establish the known side effects. WLI are no different, and have been through these trials. Some of the earlier ones have been around for decades, and no serious long term health implications have been identified. There is no rationale for avoiding WLI based on this as an "issue".
6, for some people, it takes away accountability for their own health.
Again, huh? How so? I am totally accountable for my own health, I'm paying around £50 a week to do so, and have committed to a long term weight loss process. Anyone who takes WLI is doing the same. What is the reason that you think people become unaccountable for their own health? What evidence do you see of this that concerns you?
7, my own observation: FIL (78) was put on them for his diabetes... he's lost weight and aged beyond recognition in the space of 3 months. Now this could be a natural occurrence but I would like to see some research into this.
Losing weight is an known side effect of Mounjaro, which I presume your FIL is taking? If it's too much then his diabetes team should be reducing his dose, or using a different medication. This is really specific to your FIL's personal circumstances, and is irrelevant to any discussion about WLI in general. Ditto for the "aged beyond recognition" comment. No idea what you mean by this - do you mean in terms of appearance, or in terms of health? I would point out that at 78, you might expect to age....
