Wow, some very misinformed and really quite old fashioned views being trolled out here.
I do understand the sceptiscm. The diet industry has been promising quick fixes and miracle solutions to weight loss for ever, and we are all just part of that hamster wheel. The idea that there is something that can disrupt that is actually quite subversive.
These "new" drugs are not that new. They have been around and used for 18 years in different ways.
They are NOT a quick fix. People still need to watch what they eat and exercise for them to be effective (contrast with the ridiculous amphetamine type ones of the 70s)
They seem to work by quieting that part of the brain that leads to impulsive eating. Unless you have experienced what is often referred to as "food noise" you will find this hard to relate to. It is a very separate feeling to normal hunger - and almost physiologically hard to resist.
This "food noise" can be triggered by different things - undiagnosed ADHD (sensory and dopamine seeking), adverse childhood experiences, traumatic life events etc)
Once you become "fat" it is almost impossible to lose the weight again. (Post weight loss your daily calorie needs drop by about 20% lower than someone who has never dieted), combine that with the "food noise" and you end up with yo-yo weight.
There is some emerging evidence to show that those who use these semaglutides and able to maintain weight loss - suggesting that they are also helping to reset the bodies set points and metabolism.
But there is also an argument that these will become a long term treatment for some people (not unlike statins or the use of steroid inhalers for asthma)
They are truly going to revolutionise weight loss for many people - and with that the burden on the NHS in terms of future health problems.
We need to see obesity as a medical problem, not a moral failing, and treat accordingly.
