This study assessed whether individuals with dementia who observe aquariums increase the amount of food they consume and maintain body weight. The sample included 70 residents in dementia units within 3 extended care facilities in 2 states. The intervention included the introduction of an aquarium into each common dining area. A total increase of 196.9 g of daily food intake (25.0%) was noted from baseline to the end of the 10-week study. Resident body weight increased an average of 2.2 pounds during the study. Eight of 70 residents experienced a weight loss ((Equation is included in full-text article.)=1.89 lbs). People with advanced dementia responded to aquariums in their environment documenting that attraction to the natural environment is so innate that it survives dementia.;
