6. Pistachios Can Help You Manage Your Weight
It’s not hard to eat too many pistachios at one sitting, and you’ve got to watch yourself even though they’re in low calories. However, opting for pistachios in their shells seems to help with weight control.
According to a study, those who had to open shells to eat the pistachios ate less than those who were fed them de-shelled. They ate about 40% fewer calories overall. All those shells accumulating seemed to be a kind of psychological or evolutionary hint to stop eating.
It also takes more effort and time to open those shells. Most people are lazy and would rather just eat them de-shelled.
