I haven't ever said people are jealous. If you want them, you can get them, so it's not envy in that sense. My issue is that people seem to think fat people shouldn't use them as they should suffer for thinness.
Regaining weight if you return to your initial state is obvious, surely. And a reminder to all that they aren't a magic cure. If you take blood pressure medication and come off it and your blood pressure rockets, no one (sane) is surprised, are they? I know that I need the medication to suppress my overwhelming urge to eat. Without it, I will return to bingeing, which is what got me here.
It's not a substitute for healthy eating is it? If you don't eat healthily, you won't lose weight. You can't override the suppression, gorge on cake and then expect to lose weight. Perhaps that's where the misunderstanding comes from? I don't know.
Personally, I lost 7 stone in 2020/21 and developed an incredibly unhealthy relationship with food from being so afraid to eat anything if I couldn't know the exact calories. I regained all the weight (and more) over the following few years before starting WLI's in 2025. This time, I can eat until I'm full, I crave healthy foods and water and have no desire to eat junk. I don't have to spend all day obsessing over what I eat (or what I can't eat), so yes it's 'easy' in that sense, but that doesn't mean my diet isn't better.
Smokers and drug addicts could both overcome their addictions without medication, but you'll be hard pushed to find a Mumsnet thread on the dangers of varenicline or methodone.
