That is why I suggested that any pharma approach rather than conventional changing of eating habits might be difficult to sustain
@Itcostshowmuchnow how much have you tried to learn about the way WLIs work and how much do you understand about other existing diets aka 'conventional changing of eating habits'?
Firstly, how do you think people on the drugs lose weight? They change their eating habits. The drugs facilitate that change. Someone on the drugs will eat differently for the time it takes to lose the weight. They will eat less than before because the drugs affect appetite and satiety. Anyone prescribed the drugs is advised to follow healthy eating guidelines, and many people find that if they do attempt to eat very processed, sugary or fatty foods that it causes side effects. So someone taking the drugs for say, six months, will have the experience of eating differently for that period of time. Coming off the drugs, they can continue that way of eating or not - just like any other diet.
Do you think these injections are likely to be most obese people's first attempt to lose weight? The drugs cost around £150 per month and can cause some unpleasant side effects. They are also newly available. Most obese people have tried to lose weight in the past through other routes. If you've done that, then you understand the principles of eg Slimming World, low carb, intermittent fasting, Weight Watchers, Noom, tracking calories etc. What you might not understand, OP, is that 95% of people who lose weight through these methods regain all the weight they lose plus more within a few years of losing it. You can read high quality studies about this; the research and conclusions are freely available online. So when you look at an obese person, you are likely to be looking at someone who has experience of losing weight and an understanding of how it works. But they haven't been successful at maintaining it. Most people who lose weight are not successful at maintaining it.
The injections might turn out to be the same as those other weight-loss methods; people might regain the weight plus more when they come off. But maybe the pharmaceutical element will change the outcome. Maybe it won't. Maybe people will stay on them for life and maintain their weight loss. Maybe people will be able to come off them and do it without the drugs. I imagine it will vary from person to person. But I don't think the injections can have a worse success rate than current 'conventional changing of eating habits' which see 95% of people regaining more weight than they lost. And if they do, what does it matter to you, OP?
People are taking these injections because they don't want to be obese anymore. Paying the cost, accepting the side effects, because they want to lose the weight. No one has satisfactory answers to the 'obesity crisis' and stating what is true or not 'in your book', OP, isn't all that helpful to most people. People taking these drugs may or may not regain the weight. The same is true for anyone on the calorie-counting boards, the fasting boards, the low-carb boards etc. Anyone on these forums is trying, and I can't see what you think you're contributing when you come on and tell these people that they're stupid (don't understand anything about nutrition) and doomed to failure (will put the weight back on).
If you want to understand more, then you need to let go of your existing assumptions and prejudices. You need to accept that what you think you know about obesity might not be a well-informed and knowledgeable perspective and that it might be more complicated than you believe, and that your personal experience in life might not be the same as everyone else's. That's if you actually do want to learn something rather than just tell obese people they're getting it wrong.
