Study: Weight isn't the real issue
Big Liberty has already covered this on her blog, but I wanted to add a note about it here, too.
HAES advocates keep saying over and over again that weight isn't the real issue. If you have an issue with cardiac risk factors, then it's best to address those risk factors by tweaking your habits and, if necessary, using drugs. The same is true if you have an issue with high blood sugar. Control the blood sugar, and let your weight do whatever it's going to do in response to any changes you make. The number on the scale isn't the main issue.
Now, there's a study that strongly supports that view. It's a high quality analysis of population level data.
Anthony Jerant, Peter Franks. “Body Mass Index, Diabetes, Hypertension, and Short-Term Mortality: A Population-Based Observational Study, 2000–2006″ J Am Board Fam Med July-August 2012 vol. 25 no. 4 422-431
If you follow the link above, you'll find that the entire text of the study is available for free.
In analyses not adjusted for diabetes or hypertension, only severe obesity was associated with mortality (adjusted hazard ratio, 1.26; 95% confidence interval, 1.00–1.59). After adjusting for diabetes and hypertension, severe obesity was no longer associated with mortality, and milder obesity (BMI 30-<35) was associated with decreased mortality (adjusted hazard ratio, 0.81; 95% confidence interval, 0.68–0.97). There was a significant interaction between diabetes (but not hypertension) and BMI (F [4, 235] = 2.71; P = .03), such that the mortality risk of diabetes was lower among mildly and severely obese persons than among those in lower BMI categories.
Yes, not only were even the highest BMIs only weakly associated with excess mortality, fat diabetics are less likely to die than thin diabetics. This study also found that people with BMIs under 35 do not have an elevated mortality risk at all, not even when diabetes and heart disease aren't controlled for.
