What does weight-based dosing refer to in nutrition support?

• A. Using body weight (kg) to calculate nutrition targets, such as g/kg/day of protein and kcal/kg/day of energy.
• B. Using room-based portion sizes.
• C. Using metabolic rate measurements to set calories.
• D. Calculating energy only by age.

Answer: (A)

Weight-based dosing means tying daily nutrition targets directly to a person’s body weight, expressed as grams of protein per kilogram per day and calories per kilogram per day. This approach scales intake to how big the person is, helping ensure enough protein for tissue repair while matching energy needs to size. For example, a person weighing 70 kg might have protein targets around 1.2–2.0 g/kg/day and energy targets around 25–30 kcal/kg/day, with adjustments for factors like illness or obesity (sometimes using adjusted body weight). Other methods that don’t reflect body size—such as using room portions or relying on metabolic rate alone or age-based calculations—don’t tailor intake to how much the body weighs, so weight-based dosing is the best fit for setting accurate nutrition targets.
