The study also found that being overweight or obese did not have a significant impact on mental well-being levels, contradicting the 'jolly fat' hypothesis.
Consuming tree nuts like pistachios is associated with lower risk factors for metabolic syndrome, including abdominal obesity, hypertension, and elevated fasting glucose. Pistachios are also high in fiber, vitamin B6, manganese, and copper, making them a healthy snack option that can aid in weight management and support heart health.

A synthetic compound with the same effect has been developed, offering hope for a new drug to boost tumour suppressors or improve nutrient metabolism.
A recent study published in Obesity by Rutgers University researchers found a link between genetic variation in CD36 and the ability to perceive fatty acids. Those with this variation were more sensitive to fat texture but preferred high-fat foods, highlighting a potential genetic basis for obesity development.
