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 yesterdays 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 newlyregistered account       Sounds like were doing the right thing then       Keeping it off   Keeping the weight off requires a personal touch httpjamaamaassnorgcgicontentabstractetoc      seen as a sign of lower socioeconomic status Obesity is often seen as a sign of lower socioeconomic 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 socioeconomic status is prejudice  Why mention the predjudice unless in a section on prejudice against the obsese    Antifat  made some pretty sweeping changes to the introduction and opening sections Edit summaries seem to indicate that the content was antifat but what came instead was a weaselword laden attempt at NPOV I dont 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 peerreviewed 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 its 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  alibis news item led to a pretty highprofile review of additional explanations for the obesity epidemic that is highly quotable      Units Units in first paragraph The mgkg should be kgm  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 valueneutral term like that
