has anyone been required to lose 10% of your weight ? My doctor never said anything about losing any. Is it not required by all docs ?

If I've learned anything on this forum it is that all docs are different! Mine has a lose 5% of your current weight policy...

Mine said 5% minimum, but aim for 10%.

Yes they want to see if you will loose wright on your own to see your commitment .

Yeah, I have a 5% requirement.

Mine doesn't require a weight loss pre-surgery, but it is encouraged because it will help with surgery by ridding your body of some of the internal fat they have to get through. And, of course, the commitment factor. My appt. with surgical dietitian yesterday was very helpful and she was encouraged by what I'm already doing to help myself be successful post surgery. Changing habits now will go a long way to help you adjust post surgery (at least that's what I'm reading and hearing).
