"...meta-analysis in sample of 82 864 individuals... In age- and sex-adjusted models only, BMI was related to [cardiovascular disease] mortality but not in any other analyses... In conclusion, [waist circumference and waist-to-hip ratio], but not BMI, were related to an increased risk of [cardiovascular disease] mortality.

"...metabolically healthy, but obese (MHO), despite having large amounts of fat mass compared with at risk obese individuals shows a normal metabolic profile, but remarkably normal to high levels of insulin sensitivity. Preliminary evidence suggests that this could be due at least in part to lower visceral fat levels and earlier onset of obesity. A second subset, termed the metabolically obese, but normal weight (MONW), present with normal body mass index, but have significant risk factors for diabetes, metabolic syndrome, and cardiovascular disease, which could be due to higher fat mass and plasma triglycerides as well as higher visceral fat and liver content..."
