Cutting carbs only helps to the extent you’ve reduced calorie intake.
People drop their calories too low, and then they take a cheat week after a year or so where they eat pasta, and suddenly they feel a lot better and they’re back to eating more calories and back to gaining weight, leading to yo-yo dieting, which may even be worse than just having a higher than healthy but static weight.
Friends doing it also had the same experience as I did.
Not saying it isn’t as advertised, but everyone on it I knew (n=14 or so) was getting results from fewer calories after we all decided to start carefully logging food intake.
It’s a great diet that works, but via other mechanisms for many vs ketosis.
It’s still a restriction diet that poses a lot of challenges for most to remain consistent with on a long term basis.
I see in other replies that you've had success in losing weight, and congratulations - but that doesn't mean it can work for everyone else.
I don't look at any kind of "pill solution" lightly, and absolutely think lifestyle changes should be made as well - but I can definitely see how medication like this can help get people on track and get back control. It's very encouraging to hear about psychological effects in terms of self-control, decision making etc. I'm just worried that we'll discover serious negative side-effects before too long, as with previous attempts.
