Pistachio Shell Offers Visual Cue
In Dr. Painter’s second study, in-shell pistachios were consumed over an 8-hour shift. On the first day the empty shells were left on the desks as a visual “reminder” of consumption and on the second day the shells were removed. Results showed that when the shells were left on the desk as a visual cue subjects consumed 23% fewer calories.
Interestingly, despite the reduction in calories, they reported feeling equally as satisfied as the control group that consumed more calories.
