The US studies are limited, but my understanding is that where the balloon has been used longer (ex: Europe and Australia), they have seen better results (probably just because they have more data points). I'm not even half way through my six months with Orbera and I have lost 33 pounds. I also know of two men who lost more in that same amount of time (one Orbera and one ReShape). As with most things, a lot of it depends on how much you put into it. It's not a cure, it's a tool. You still have to do a lot of work, counting calories and Protein, exercising, etc.. If you use it to assist you with behavioral modification, six months is more than enough time to establish healthy habits that can last you a lifetime. Best wishes!
