`         == exercise vs diet ==  The article currently says ``exercise combined with diet resulted in a greater weight reduction than diet alone``.  But that makes me wonder  are there any studies comparing exercise alone vs. diet alone? Is ``weight loss from exercise combined with diet`` an additive effect of ``weight loss due to exercise`` plus ``weight loss due to diet``, or is there a  synergetic effect?     ==Protection== Indefinite protection is not usually a good idea, but yesterday's unprotection of this page shows that it is a vandal magnet. I have yet to see a useful edit to this topic from an anon or newly-registered account.  |    : Sounds like we're doing the right thing then.      == Keeping it off ==  Keeping the weight off requires a personal touch: http://jama.ama-assn.org/cgi/content/abstract/299/10/1139?etoc  |    ==seen as a sign of lower socio-economic status== ``Obesity is often seen as a sign of lower socio-economic status`` sounds strange to me. Obesity correlates with low economic status. That is a fact and could be mentioned. But to see obese people as of lower socio-economic status is prejudice.  Why mention the predjudice unless in a section on prejudice against the obsese?    ==Anti-fat?==  made some pretty sweeping changes to the introduction and opening sections. Edit summaries seem to indicate that the content was ``anti-fat``, but what came instead was a weasel-word laden attempt at NPOV. I don't think that there are many experts who disagree that prevalence of obesity is increasing or that it predisposes to many medical conditions. The news article that was inserted in the intro replaces peer-reviewed evidence already cited with ``personal opinion`` by ``experts`` with a sniff of conflict of interest. That may technically belong somewhere in the article, but is really not suitable for the intro.  |    :For what it's worth, some of the additions lead to very interesting sources. I had heard of the UK twin study, but have now identified the actual reference and added it (in preferment over news articles that have the habit of dumbing down the data). The ``10 alibis`` news item led to a pretty high-profile review of additional explanations for the ``obesity epidemic`` that is highly quotable.  |    ==Units== Units in first paragraph The mg/kg2 should be kg/m2  —Preceding unsigned comment added by      ==Usage of the term ``healty weight``== Given that there is conflicting evidence about the health effects of obesity, I propose that the term ``healthy limits`` in the first paragraph be changed to ``established limits,`` or some other value-neutral term like that.   `
