Healthy obesity

All unapproved Citizendium articles may contain errors of fact, bias, grammar etc. A version of an article is unapproved unless it is marked as citable with a dedicated green template at the top of the page, as in this version of the 'Biology' article. Citable articles are intended to be of reasonably high quality. The participants in the Citizendium project make no representations about the reliability of Citizendium articles or, generally, their suitability for any purpose. This article is currently being developed as part of an Eduzendium student project in the framework of a course entitled Appetite and Obesity at Edinburgh University. The course homepage can be found at CZ:UoE Appetite and Obesity 2011. For the course duration, the article is closed to outside editing. Of course you can always leave comments on the discussion page. The anticipated date of course completion is 01 April 2012. One month after that date at the latest, this notice shall be removed. Besides, many other Citizendium articles welcome your collaboration!

Although obesity is a major risk factor for cardiovascular disease and type 2 diabetes mellitus, about a third of obese individuals maintain healthy cardiometabolic profiles; this phenotype of healthy obesity may be linked to the location of adipose tissue and the metabolic characteristics of the fat. Some data also suggest that weight loss by healthy obese subjects may have an adverse impact on their favorable cardiometabolic profile.

Evidence for the existence of the healthy obese category:

Conflicting findings of meta-analyses from NEJM and American heart journal etc. the impact of adjusting for physical activity and the role of other parameters. eg. lack of any the metabolic syndrome criteria & no insulin resistance counts as healthy. non metabolic morbidity.

or if that overlaps too much with someone else's section I could cover:

the role of ethnicity: A higher proportion of black healthy obese? Possible underlying mechanism?
