Body Mass Index (BMI) is an inadequate and potentially misleading metric for assessing individual cardiometabolic risk because it fails to account for regional fat distribution and ectopic lipid deposition, which are the true drivers of disease.
Stop using BMI as your primary health metric. Instead, focus on waist circumference and metabolic markers (blood pressure, lipids, glucose). If you have a high BMI but a small waist and good metabolic markers, your risk may be low. Conversely, if you have a normal BMI but a large waist, your risk may be high. Prioritize lifestyle habits (diet quality, physical activity) that reduce visceral fat rather than just total weight.
BMI... only provides a crude assessment of the amount of body fat... this anthropometric index is of no use to assess individual variation in the regional distribution of body fat... results of genetic association studies linking BMI to cardiometabolic diseases suggest that most if not all of the contribution of BMI to cardiometabolic diseases is driven by central body fat distribution and not via a high BMI per se.
Why this rating
Supported by observational, genetic (Mendelian randomization), and mechanistic evidence from large cohorts (UK Biobank, Framingham).

- Visceral Adipose Tissue (VAT) and ectopic fat deposition are causal drivers of cardiometabolic disease, whereas subcutaneous fat (specifically gluteofemoral adipose tissue, GFAT) is protective, independent of total body weight.Strong
- Lifestyle interventions (diet and physical activity) improve cardiometabolic risk through mechanisms independent of weight loss, primarily by reducing visceral and ectopic fat and improving metabolic markers.Good

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
