Full definition
BMI is weight in kilograms divided by height in metres squared (kg/m²), used to classify overweight and obesity.

Indian guidelines often consider GLP-1 obesity therapy at BMI ≥27.5 or ≥25 with comorbidities. Waist circumference supplements BMI due to thin-fat phenotype in South Asians. In India, these concepts appear in RSSDI and ICMR guidance for type 2 diabetes and obesity care—always confirm details with your prescribing physician.
