I've got to say, pretty frustrating seeing answers like this. It just completely ignores all the real, valid difficulty that people have in fighting obesity. If you "just" follow this diet, that requires discipline, strong will, buying correct supplies, 2h of cooking a day, measuring, counting, adhering to strict eating timeline, for months (years for some people), you'll be golden! There is plenty of research into behaviour changes with obesity and mechanisms that prevent good decision making etc - apart from just the practicality of all of the above in one's daily life with work, kids...

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.

This is about as useful as telling someone who's obese to just eat less. Factually yes, it might help them, but practically they're clearly unable to implement it, probably for a plethora of underlying reasons.

I read your experience and it is indeed pretty incredible and I'm happy for you. I've used ketosis strategically for athletic reasons, to cut weight. So we both had strong motivations to use it. But for your typical obese person, it is a tremendous challenge to stick with it and at the end of the day, it's adherence that matters.

Put simply, it's easier to adhere to a drug than to a specific, somewhat anti-social diet.

It is not easy on the mind and body as to just cut carbs.

This is true, but fat people have a hell of a time cutting out all carbs. For many of them, they'll eat the "low carb" option, and then have an occasional binge and it negates any benifits of low carb, and doesn't put them in ketosis, etc.

I strictly maintain my weight. If I catch it going over over 155# (I'm a 5'10" 61 year3 old male) I'll do a strict cut. And I know that either strictly counting calores OR going to as close to zero carbs will have the same net effect.

But a person who has obesity or is overweight will not be able to follow a diet. They are just incapable of doing so, or will lie to themselves or others about it and claim it's their "metabolism" or a medical condition, etc.

You can just cut ultra-refined foods i.e. junk foods. No one is getting obese from lentils, broccoli and apples. Even so, avoiding weight gain is one thing and losing weight is another. While it helps to increase ratio of protein and fiber intake for satiety, that in itself does not guarantee a caloric deficit, which is what is necessary for weight loss.
