Obesity without metabolic syndrome ('metabolically healthy obesity') significantly increases the 5-year cumulative incidence of hypertension and diabetes compared to lean subjects without metabolic syndrome.

If you are overweight or obese, even if your current blood pressure and blood sugar are normal, you are at a significantly higher risk of developing hypertension and diabetes within five years compared to someone of normal weight. You should not assume 'normal labs' mean 'no risk.'

GoodSupportsHIGH confidence
Subjects with overweight/obesity but without metabolic syndrome carried increased cumulative incidence of hypertension (14.6% vs. 7.2%, P < 0.001) and diabetes (2.6% vs. 1.1%, P = 0.004) over 5 years compared to lean/normal subjects without metabolic syndrome.
