If they have a ‘normal’ body and no psychological issues they may be able to keep the weight off.
I have an abnormal body that unfortunately doesn’t work well (I can only eat 1000 calories a day without putting on weight) so I will be on them forever.
The injections make it possible to stick to 1000 calories, without them I have to fight (and am hungry all the time) to stick to 1300.
I have no problem staying on them forever.
They have been transformative for me, I’m on the go all the time and have very low inflammation now so I can run and exercise all the time. I have learned to trust the injections, some days when I’m very active I will eat as much as 1500 calories, other days when I’ve just had the injection or I’m working and sitting so much less active I’m only eating 600-800.
It averages over the week at 1000 calories a day so maintaining the weight. For decades I was at war with my body and was constantly fighting to consume less than 1400 calories, I was tearful + hungry and annoyed with myself all the time.
I could not frame it as my body being at fault when it WAS. The truth was I had MOUNTAINS of willpower, being able to ‘only’ put on 8 stone over 27 years showed that I ‘only’ overate by a couple of hundred calories every day.
No one can cheerfully eat that little without the injections, it’s unreasonably low.
I still have to ‘work’ at it. I do intermittent fasting every day, I eat very low UPF, I eat protein first, veggies next and don’t eat bread anymore. I also make sure I meet my activity goals on my Fitbit every day (move every hour) + do 3 exercise classes a week.
But the injections mean I enjoy doing the above ^^ none of it’s a chore or painful.
