What is the recommended daily caloric intake per kilogram for older adults?

• A. 25-30 kcal/kg
• B. 20-25 kcal/kg
• C. 30-35 kcal/kg
• D. 35-40 kcal/kg

Answer: (C)

Older adults typically have slower metabolism and often lower activity levels, so their total daily energy needs are reduced. Expressing energy needs per kilogram helps tailor intake to body size while aiming to preserve lean mass and overall health. For most older adults, about 30 to 35 kcal per kilogram per day provides enough energy to maintain weight and support basic bodily functions without suggesting excess intake. This range balances the risk of undernutrition—common in aging—with the desire to avoid excess calories that can contribute to weight gain or metabolic strain in this population. Options with lower values could risk energy shortfalls for many older adults, while higher values are often unnecessary given typical activity levels and can be harder to sustain. Thus, the recommended range is 30-35 kcal/kg/day.
