Adjusted body weight is about 75.6 kg.

  • Your ideal body weight is about 65.9 kg, and your adjusted body weight is 75.6 kg (136% of ideal).
  • Adjusted body weight sits between ideal and actual weight because only part of the excess tissue in obesity is metabolically active and needs dosing or nutrition support.
  • Because your actual weight is more than 20% above ideal, clinicians often use adjusted body weight for drug dosing and calorie estimates rather than your full weight.

Next stepConfirm with your clinician which body weight (actual, ideal, adjusted or nutritional) is appropriate for your specific medication or nutrition plan.
