I can't say I agree with this analysis. In the first instance, the fact that both parents' obesity is a factor could be argued to point towards a stronger correlation. In a broad sense, it's also important to note that chronic diseases always have some behavioural and lifestyle component. For example, physical malformations can be caught early and given therapeutic redress -- Scoliosis correction might be a good example.

You're not condemned to be obese if your genetics give you the propensity for it, but it's also fair to say that the genetics mean that disease-like interventions are necessary. http://www.hsph.harvard.edu/obesity-prevention-source/obesit...
