And lack of obesity is not a protection. The study confirms that obesity and metabolic syndrome are most likely unrelated causually, although may be coincidentally correlated to some extent.
A new UK study is discussed here.
"People with good metabolic health are not at risk of future heart disease -- even if they are obese," Hamer told Reuters Health.
On the flip side, the non-obese in poor metabolic shape face as much risk as the unhealthy obese, the researchers concluded.
The findings, published in the Journal of Clinical Endocrinology & Metabolism, are based on more than 22,000 middle-aged participants in national health studies conducted in England and Scotland.
According to the researchers, the results suggest that metabolic factors may be more important in predicting a person's risk of cardiovascular disease than excess body weight in itself.
