Whereas helpful in sure medical settings and for broad information units in epidemiologic (population-level) analysis, BMI shouldn’t be as helpful on the particular person degree in case your objective is a complete and personalised method to optimize metabolic well being.
BMI is insensitive to physique composition nuance (e.g., a muscular and extremely match athlete could register within the “chubby” or “overweight” classes), gender, and racial uniqueness. As mbg Collective member and the daddy of purposeful drugs Jeffrey Bland, Ph.D., beforehand shared with mbg: “The BMI normal was developed for an idealized Caucasian male, and the thresholds stay moderately oblivious to essential discrepancies warranted by gender and ethnicity.”
