But it's also true that most methods of weight loss also have some if not total weight gain when those methods become unsustainable again.
And they can easily become unsustainable. People get new jobs all the time that take up more time and energy, longer commutes, more children, less energy, injury, chronic pain, illness, boredom, the community we keep around us and their influences, and so on.
This is why obesity is a lifelong disease and needs to be treated as such.
I haven't pushed the OP towards WLI, in fact I've been very respectful of her desires not to try them, but I also understand that other obese people are finally grateful that there is a medication to help them with their disease.
I have tried the medications myself, loved them, but wasn't losing weight as fast as many other people, and it was still impacting my mobility, and ability to actually cook food, play with my little boy, and do sustained activities even walking for an hour.
I'm over 16 stone with a BMI of 46, I'm very short, and when I was religiously calorie counting I found it hard to eat over 800 calories and lose weight. That was with the injections that still curbed my appetite. I did get my BMI down on the WLI but it kept creeping back up.
I have been referred and approved for weight loss surgery now, which is the last resort, and an irreversible step towards recovery for obesity.
I applaud the OP for wanting to try everything she can now before it gets to medication or surgery because I don't think any one should get to this point and have to make these sorts of choices lightly.
It is dismissive though to slate these weight loss injections because the cessation of them means that you're likely to regain the weight. Many people have accepted they'd need these medications for life in the same way diabetics would need medication for life because the reality is you can't just cure a disease through willpower alone, willpower has it's limits and isn't entirely reliable.
