Obesity is an independent risk factor, even if otherwise active/healthy. It's worth getting under control for lifespan and healthspan.
- rootusrootus 11mo agoAcross the population as a whole, BMI 30 is basically negligible increase in all-cause mortality. For someone otherwise reasonably active I wouldn't stress about the number. Ideal is somewhere around 27.
- wotmatetherow 11mo agoWhere are you getting this number? Over 27% body fat is a health risk. For an active but not muscular individual, 30 BMI is at least 33% body fat, likely higher.
- rootusrootus 11mo agoFrom the multitude of studies, in particular the relatively recent huge multi-study analysis of all-cause mortality vs BMI.
- nradov 11mo agoBMI is useful for screening purposes but on an individual basis it's meaningless as a predictor of all-cause mortality. What really matters is body composition, or more specifically amount of visceral fat (subcutaneous fat doesn't matter nearly as much). https://my.clevelandclinic.org/health/diseases/24147-visceral-fat https://my.clevelandclinic.org/health/diseases/24147-viscera...
- andsoitis 11mo agoBMI over 25 is overweight. Obese is 30 or higher.
- lucyjojo 11mo agobmi doesn't mean much though. size, body composition, ethnicity will give very different meanings to the same bmi.
- rootusrootus 11mo agoYes, those are the definitions we have assigned to the number. However, independent of the arbitrary labels, the actual impact on health matters more to me.
- trjordan 11mo agoSure. I lost 20lbs in the last 12 months. I agree it’s worth working on, but not that it’s worth stressing about.
