The only way to tackle this is to be brutally honest.
Food noise is torture. And for the ones of us who have yo-yo dieted for most of our lives, food is a delicious reality, while being thin is a beautiful, but often unattainable dream. The thought of not being able to enjoy our tasty chocolate, cakes, snacks, whatever feeds your cravings... for years on end, is miserable. When I was on a diet I cried thinking of how my days were spent sad and miserable, and hungry, and still never managing to be thin. I never got any prizes for my efforts. And even when I managed to lose significant amounts of weight... I was always terrified of putting it back on, and dismayed when it then happened.
The weight loss injections allow us to get rid of that food noise, and take away the misery of dieting. And they give us our dream on a plate (excuse the pun). To the point that even the thought of being on the drug for life, even the thought of future side effects... pales in comparison to what most of us have gone through before the injections existed.
It is a vicious circle. Who on earth wants to spend their life being miserable, hungry and anxious, surrounded by tempting treats and judgmental stares at the same time? If we're fat we get the disgusted comments and stares. If we enjoy a tasty treat people think we're disgusting. If we're losing weight we can't enjoy it, because we can't fucking stop thinking of the food we're missing, and the weight loss is so slow and frustrating that it takes ages for anyone to even see the difference. Our only options are misery, in different packages.
How are we not going to love the injections? They offer us what we never thought we'd have! Rapid weight loss, no food noise, easy dieting. The body we never thought we'd see on the mirror. Of course, deep inside, we know this is too good to be true. But right NOW, it is so good, and so true, that our brain does not even want to consider the future.
I have no solution for this. I don't think there is any right now. If maintaining the weight using diet was possible, then we wouldn't need the injections to start with, right? Everyone would be just dieting. And succeeding. But we're not.
