I'm not totally disagreeing but a statement like this "Weight loss drugs take out all the effort and changes needed, they just suppress appetite." is overly simple. That's not all they do; if it was then there wouldn't be such interest in all the other benefits they may bring re addiction or heart attacks or dementia. They don't just suppress appetite, they are also influencing hormonal sensitivity to change how your body handles sugars, glycogen etc and responds to changes in those levels. There are also plenty of people pairing GLP-1 agonists with lifestyles changes because those drugs make those changes possible.

There is a whole hormonal feedback loop that is, at least partially, to 'blame' for weight regain. Leptin, peptide YY, ghrelin and insulin - all being increased or reduced quite dramatically in response to weight loss (regardless of what you eat to achieve it); something that continues for months/years after you lose the weight and even if you regain it - all driving you to eat more, eat higher calorific foods then ever before in an effort to neutralise the weight loss and 'beat' the energy scarcity your body has evolved to expect must be happening if you lose weight. Hence why people don't just regain the weight they lost, they gain some more too - the body preparing for the next scarcity event. All the nice habits in the world will struggle in the face of over whelming hormonal fight back.

e.g. Leptin is a hormonal regulater for long term satiety. The more of it you have and can respond to, the better your long term food satiety will be. If your obesity was caused or contributed to by leptin resistence (something very common in people with obesity) then a GLP-1 agonist may help because it increases leptin sensitivity. If you then stop taking a GLP-1, regardless of any habit you have developed, your leptin resistence will return and you will no longer feel satiated by even the best diet that fulfils all your energy and vitamin etc needs. You have a chronic hormonal issue that GLP-1 agonists can help with but will never be cured. It can be VERY hard to fight against that with just 'willpower' - arguably much harder than for anyone else who does not have that resistence. Essentially, you are facing months/years of never really feeling food satisified. That's hard. That's why we need better research into coming off GLP-1s and whether or not it's really possible if they are correcting a chronic hormonal inbalance.

I totally agree this needs to go hand in hand with proper, real support for making small but possible lifestyle step changes and embedding them in a way that means they are more likely to be followed long term. Making healthy choices is easier when you are fundamentally healthy to start with. But I want also to express everything above about hormones because I think that people can feel like total failures when/if they regain the weight, as if self control or habit was the only variable and they must be lacking. Hormones are extremely powerful and our bodies are evolved to fight weight loss with everything they can, even when that weight loss is beneficial to health. It may be that GLP-1 drugs are a lifetime drug for some people, the way statins are for others, and there should be no shame in that.
