The Tenth Doctor dies and regenerates into the Eleventh Doctor
No, the Master survived, and in the new years special of Doctor Who, 2009/2010, they all return only to die again.
well, First off, his name is "The Doctor" and no, he doesn't die, he regenerates. in the last Christmas special, the 11th doctor (who was on his last regeneration) was granted another set of regenerations, so we can expect many more seasons of the show ;)
Presuming you mean David Tennant, there isn't a set date. But in the 2009 specials of Doctor Who, David Tennant will appear in all of them so therefore the last shall be his regeneration. It is assumed that December is the most likely time. Possibly Christmas Day. Possibly New Year's Day. Or maybe even in January. So winter is the only definite answer I can give.
Did you mean a special diet? If so, yes there is a special diet for gastric bypass surgery candidates. Speak with your doctor who can give you all the information you may need.
No, Chris Brown does not die in This Christmas.
At some point, the Doctor will regenerate again. This is a device to allow different actors to play the same character over several decades. Regeneration causes not only a different physical appearance, but a new emotional outlook and new personality. Look for Matt Smith's Doctor to regenerate some time after the fiftieth anniversary season begins in 2013.
